Enter your quote amount and zip code. We compare it to 2026 pricing data for your specific job, home, and location and tell you whether the price is fair, above average, or overpriced. You also get a line item scorecard, a company trust checklist, and word-for-word scripts for what to say if the price is too high.

How to Tell If Your Plumbing Quote Is Fair

A fair plumbing quote falls within the typical range for your service type, adjusted for four key factors: the specific work being done, the complexity and access difficulty, your geographic location, and whether the work is standard or emergency. Understanding these factors gives you a reliable framework for evaluating any quote you receive.

The Four Factors That Determine a Fair Price

Service type is the biggest price driver. A simple faucet cartridge replacement ($75 to $250) and a whole-house repipe ($3,000 to $10,000) are both "plumbing work," but the scope, materials, time, and skill required are entirely different. The quote analyzer above uses service-specific pricing data rather than generic averages, which is why it asks for the exact job type.

Complexity and access account for the second biggest variable. Fixing a leaking pipe under a kitchen sink (accessible, 30 minutes) costs $150 to $500. Fixing the same type of leak behind a tiled shower wall (requires demolition, 3+ hours) costs $300 to $1,500. The repair itself is similar; the labor to reach it is what drives the cost. Slab foundations add 10 to 20% for any below-floor work because the plumber must either tunnel under the slab, break through concrete, or reroute the line.

Location creates a 20 to 30% swing in pricing across the United States. A plumber's hourly rate in San Francisco or New York ($100 to $180/hour) is 40 to 60% higher than the same rate in Atlanta or Indianapolis ($70 to $130/hour). This is driven by cost of living, licensing requirements, and labor supply. The quote analyzer adjusts for your zip code automatically.

Urgency is the final factor. Emergency and after-hours plumbing calls carry a legitimate 40 to 80% premium over standard business hours pricing. A drain cleaning that costs $100 to $250 on a Tuesday morning costs $200 to $450 at 10 PM on a Saturday. This premium covers overtime labor, on-call availability, and the plumber leaving another commitment.

Why Do Plumbing Quotes Vary 30 to 50%?

It is common to get three quotes for the same job and see a 30 to 50% spread between the lowest and highest. This does not necessarily mean anyone is overcharging. Differences come from company overhead (a solo plumber vs. a company with an office and fleet), material quality (a 6-year water heater vs. a 12-year unit), scope differences (one plumber includes code upgrades, another does not), pricing model (flat rate vs. hourly), and seasonal demand.

The best value is not automatically the cheapest price. A $200 savings on a water heater installation means nothing if the plumber uses a lower-quality unit, skips the permit, and offers no warranty. Compare value: scope, materials, warranty, and licensing.

Quote vs. Estimate vs. "Not to Exceed"

These three terms have different legal meanings. A quote (also called a bid) is a fixed price the plumber commits to. The final bill should match the quote unless the scope changes. An estimate is an approximation that can change once the plumber sees the actual conditions. It is common for estimates to increase 10 to 30%, especially for phone estimates. A not-to-exceed price sets a ceiling: the final bill can be lower but never higher than the stated amount.

For any job over $500, request a written quote or a not-to-exceed estimate. For diagnostic-type work where the scope is truly unknown, a time-and-materials rate with a not-to-exceed cap protects you from runaway costs. For comprehensive pricing data, see the full plumbing cost guide.

The Service Call Fee Explained

Most plumbers charge $75 to $150 for a service call, also called a trip charge or diagnostic fee. This covers the plumber's drive time, vehicle costs, and initial assessment of the problem. The service call fee is charged regardless of whether you hire the plumber for the repair.

Many companies waive or credit the service call fee if you hire them for the work. This is a common and reasonable practice. Always ask before scheduling: "Is the service call fee applied toward the repair if I go with you?" Fees over $200 are above average for most markets and should prompt you to compare with other companies.

What Should Be Included in a Plumbing Quote?

A professional plumbing quote should contain specific elements that allow you to evaluate it properly and compare it against other quotes. If a plumber gives you a verbal number without a written breakdown, ask for a detailed written estimate before agreeing to any work. A complete quote protects both you and the plumber by setting clear expectations.

A complete plumbing quote should include:

1. Itemized labor charges. Either a flat rate for the job or an hourly rate with an estimated number of hours. If hourly, ask for a not-to-exceed price so you are protected if the job takes longer than expected.
2. Itemized materials. The specific parts, fixtures, and materials to be used, along with their cost. A quote that just says "materials: $600" without specifying what those materials are is not detailed enough.
3. Permit fees. If the work requires a permit (water heater installation, repiping, sewer work, gas line work), the permit fee should be listed separately. Typical permit fees range from $50 to $300.
4. Scope of work. A clear description of exactly what the plumber will do, including which fixtures, pipes, or systems are affected and what the end result will be.
5. What is NOT included. Common exclusions: drywall repair after accessing pipes, concrete patching after slab work, landscaping restoration, disposal fees for old equipment.
6. Warranty information. What is covered, for how long, and whether it includes labor, parts, or both. Get this in writing.
7. Timeline. When the work will start, how long it will take, and whether you will have water during the project.
8. Payment terms. When payment is due, accepted payment methods, and whether financing is available for larger jobs.
9. Discovery clause. For jobs where hidden conditions may exist (behind walls, under floors, in sewer lines), the quote should state what happens if additional problems are found. The plumber should stop, explain the issue, and provide a revised estimate before doing any additional work.

If a quote is missing most of these elements, request a more detailed written estimate. A plumber who is unwilling to put the details in writing is a plumber you should reconsider hiring.

Red Flags in Plumbing Quotes

Not all plumbing companies operate with the same level of integrity. Knowing the warning signs helps you avoid overcharges, shoddy work, and preventable headaches. The following red flags do not automatically mean a company is dishonest, but they warrant extra caution and additional verification.

Quote Delivery Red Flags

• No written estimate. A verbal-only price with no documentation is the biggest red flag. Verbal quotes have no legal standing and frequently change once the work begins. Always require a written quote before authorizing any work.
• Phone quotes presented as firm prices. A phone quote is an estimate based on your description of the problem. The plumber has not seen the actual conditions. Treat phone quotes as a starting point and expect them to change 10 to 30% after an in-person inspection.
• Pressure to decide immediately. "This price is only good today" is a sales tactic, not a legitimate pricing constraint. A fair price today will be a fair price tomorrow. Any plumber who will not give you time to consider the quote or get competing estimates is prioritizing their close rate over your interests.
• Dramatically low quotes. A quote that is 40 to 50% below the others may be a bait-and-switch: get in the door cheap, then "discover" additional problems that inflate the final bill. Or it may indicate corners being cut: cheaper materials, skipped permits, or less experienced labor.

Scope and Recommendation Red Flags

• "While I'm here" upsells. Some plumbers use the access they already have to recommend additional work. A shut-off valve replacement while the water is already off is reasonable. Recommending a full repipe when you called about one leaky joint is opportunistic. The test: would you have sought this repair independently within the next six months?
• Quoting replacement over repair. A dripping faucet may need a $20 cartridge, not a $300 new faucet. A running toilet may need a $5 flapper, not a $400 new toilet. Always ask: "Can this be repaired, and what is the cost difference compared to replacement?"
• Refusing to explain the diagnosis. A legitimate plumber can show you the problem and explain it in plain language. If they refuse to explain or show you what is wrong, they may be inflating the scope.
• Not mentioning permits. If the work requires a permit and the plumber does not mention it, either they do not know (inexperience) or they plan to skip it (cutting corners). Both are problems.

Business Practice Red Flags

• No license number on the quote or invoice. Licensed plumbers display their license number on business documents. If it is missing, ask for it and verify it with your state licensing board.
• Large deposit required upfront. A deposit over 50% before work begins is above industry norms. For most residential work, payment is due upon completion. For large projects (repiping, sewer replacement), a 10 to 30% deposit is reasonable.
• Charging for major work estimates. Diagnostic visits ($75 to $150) are standard, but charging a separate fee to provide a quote for major work (sewer replacement, repiping, water heater installation) is not. Most companies provide free estimates for jobs over $1,000.

The Most Commonly Overcharged Plumbing Repairs

Some plumbing repairs are overcharged more often than others, typically because they are simple jobs with low material costs where the homeowner does not know what the parts actually cost. Knowing the fair range for these common repairs helps you spot inflated quotes immediately.

Running Toilet

Fair range: $50 to $200. Reported overcharges: $250 to $400+. A running toilet is almost always caused by a worn flapper ($5 part) or a faulty fill valve ($15 part). The repair takes 15 to 30 minutes. If a plumber quotes over $200 for a running toilet repair, ask what specific part is failing and why the cost is above the typical range. If they recommend a full toilet replacement ($250 to $600) without first trying the $50 to $100 repair, get a second opinion.

Dripping Faucet

Fair range: $75 to $250. Reported overcharges: $300 to $500+. Most dripping faucets need a new cartridge, O-ring, or washer. The part costs $5 to $30 depending on the brand. Labor is 20 to 45 minutes. Some plumbers push full faucet replacement ($200 to $500 including the fixture) when a $100 repair would solve the problem. Brand-specific cartridges (Moen, Delta, Kohler) may require ordering the part, which can add a return visit fee.

Clogged Drain

Fair range: $100 to $250 for a single drain. Reported overcharges: $350 to $600+. A standard drain cleaning with a motorized snake takes 30 to 60 minutes. If the plumber jumps straight to hydro jetting ($350 to $600) without trying a snake first, ask why. Hydro jetting is appropriate for grease buildup, root intrusion, and recurring clogs, not for a one-time kitchen sink backup. Also watch for unnecessary camera inspections ($100 to $350) added to a simple single-drain clog.

Garbage Disposal

Fair range for repair: $75 to $200. Fair range for replacement: $200 to $500. Many disposal "repairs" are simply a reset (pressing the button on the bottom of the unit) or clearing a jam. If a plumber quotes replacement ($200 to $500) without first checking whether the unit can be reset or unjammed, they may be upselling. Motor failure does require replacement, but a disposal that hums but does not spin is likely jammed, not dead. See our garbage disposal repair cost guide for a full breakdown.

Water Heater Flush

Fair range: $80 to $200. Reported overcharges: $250 to $400+. A water heater flush is maintenance, not a repair. It takes 30 to 60 minutes and requires no parts. If a plumber quotes over $200 for a flush, or recommends a flush alongside unrelated work as an add-on, the price is above the typical range. See the water heater repair cost guide for more on maintenance and repair pricing.

How to Negotiate a Plumbing Quote

Plumbing prices are more negotiable than most homeowners realize. The key is knowing which levers to pull and how to frame the conversation. You are not trying to low-ball the plumber; you are trying to ensure you pay a fair price for quality work.

Get 2 to 3 Written Quotes

This is the single most effective negotiation tool. For any job over $500, get at least two to three written quotes with itemized breakdowns. For major work over $2,000 (repiping, sewer replacement, water heater installation), always get three or more. Having competing quotes gives you data to work with and leverage to negotiate. A plumber who knows you have other options is more likely to offer a competitive price.

Ask What Is Driving the Cost

If a quote is higher than you expected, ask the plumber to walk you through the line items. A legitimate plumber can explain every charge. Sometimes the higher cost is justified: premium materials, code upgrades in an older home, or complex access. Sometimes it is not: inflated labor hours, marked-up parts, or bundled services you did not request.

Ask About Repair vs. Replacement

Some plumbers default to replacement because it is a bigger job with higher revenue. Always ask: "Can this be repaired instead of replaced? What is the cost difference, and what are the trade-offs?" A faucet cartridge ($75 to $150 repair) vs. a new faucet ($200 to $500) is a meaningful difference. A water heater element ($150 to $350 repair) vs. a new water heater ($1,200 to $2,500) is a major decision. See when to call a plumber vs. DIY for repairs you can handle yourself.

Request a Service Call Fee Waiver

Many companies charge $75 to $150 for a service call but waive it if you hire them for the repair. If the company does not offer this automatically, ask: "Is the service call fee applied toward the repair if I go with you?" This is a common and reasonable request that most companies will accommodate.

Supply Your Own Fixtures

Plumbers mark up fixtures (faucets, toilets, garbage disposals, water heaters) by 20 to 40%. A toilet that costs $150 at a home improvement store may be quoted at $200 to $250 on the plumber's invoice. Buying the fixture yourself and paying labor-only for installation saves the markup. Confirm the exact model with the plumber before purchasing to ensure compatibility. Note that some plumbers will not warranty a fixture they did not supply.

Schedule During Off-Peak Times

Weekday mornings (Tuesday through Thursday, 8 AM to noon) are typically the least busy times for plumbers. Some companies offer lower rates or waive the service call fee for non-emergency work during these hours. Avoid Monday mornings (backlog from weekend emergencies) and Friday afternoons (plumbers trying to finish before the weekend).

Bundle Multiple Repairs

The service call fee ($75 to $150) is charged per visit, not per repair. If you have a dripping faucet, a running toilet, and a slow drain, scheduling all three in one visit saves you two service call fees ($150 to $300 in savings). Make a list of everything that needs attention before calling. Use our plumbing cost calculator to estimate the combined cost.

Emergency Plumbing: When Higher Pricing Is Justified

Emergency plumbing rates are legitimately 40 to 80% higher than standard business hours pricing. This premium is standard industry practice, not a ripoff. It covers overtime labor, on-call availability, lost personal time, and the urgency of responding quickly to prevent property damage. The key for homeowners is knowing which problems are true emergencies and which can wait 12 to 24 hours for regular scheduling.

True Emergencies: Call Immediately

• Burst pipe or major water leak you cannot stop with the shutoff valve
• Sewage backing up into your home through floor drains or toilets
• Gas leak (you smell gas near a water heater or gas line). Leave the house first, then call.
• No water to the entire house
• Active flooding from any source
• Water heater leaking significantly (actual flow, not condensation)

Urgent but Can Wait 24 to 48 Hours

• Toilet leaking at the base (shut off the toilet valve, mop up water, schedule soon)
• Water heater leaking slowly (small drip; place a pan under it, schedule this week)
• Multiple drains backing up simultaneously (main line issue developing)
• Single fixture with no water while other fixtures work fine

Can Wait for Regular Scheduling

• Dripping faucet (wastes water but not urgent)
• Running toilet (wastes water but not a structural risk)
• Slow single drain (partial clog developing)
• Low water pressure at one fixture (clogged aerator most likely)
• Garbage disposal not working (try the reset button first)

How to Reduce Emergency Plumbing Costs

If you are facing a true emergency, the best way to minimize cost is to contain the damage before the plumber arrives. Know where your main water shutoff valve is and turn it off to stop active leaks. For toilet overflows, shut off the valve behind the toilet. For water heater leaks, turn off the water supply to the heater and the gas or electricity. These steps stop the damage and reduce the scope of the emergency call.

Understanding Plumbing Pricing: Hourly vs. Flat Rate

Plumbing companies use two primary pricing models, and understanding the difference helps you evaluate quotes accurately. Neither model is inherently better; the right one depends on the job.

Hourly Pricing

How it works: The plumber charges per hour plus the cost of materials. Standard rates range from $75 to $150 per hour during business hours. Emergency rates run $150 to $300 per hour. The final bill depends on how long the job takes.

Best for: Diagnostic work, small repairs with unknown scope, and situations where you want to pay only for actual time spent. For a simple faucet repair that takes 30 minutes, hourly pricing may cost less than a flat rate.

Risk: If complications arise, the clock keeps running. A job estimated at 2 hours may take 4 hours if hidden problems are discovered. Always ask for a not-to-exceed estimate when using hourly pricing.

Flat Rate Pricing

How it works: The plumber quotes one price for the entire job regardless of how long it takes. This is the model used by most larger plumbing companies.

Best for: Well-defined jobs like water heater replacement, toilet installation, and standard drain cleaning. You know the final cost upfront, and if the job takes longer than expected, the plumber absorbs the extra time.

Risk: Flat rates include a built-in buffer for worst-case scenarios. If your job is straightforward, you may pay more than you would at an hourly rate. The trade-off is price certainty.

Why Plumbing Seems Expensive

A plumber's hourly rate of $100 to $150 may seem high compared to other trades, but the rate covers far more than just the plumber's time on site. It includes liability insurance ($2,000 to $5,000 per year), vehicle and fuel costs ($8,000 to $15,000 per year), tools and equipment ($5,000 to $20,000 invested), state licensing fees and continuing education ($500 to $2,000 per year), workers compensation insurance, office overhead, and the 3 to 5 years of apprenticeship required before a plumber can work independently.

When you factor in these costs, a plumber earning $100/hour is taking home roughly $35 to $50/hour after expenses. The rate is not just for wrench time; it is for the training, insurance, and infrastructure that allow a licensed professional to show up at your home and solve the problem correctly.

What Plumbing Work Requires a Permit?

Most plumbing work beyond simple repairs requires a permit. If your plumber does not mention permits for a job that requires one, that is a red flag. A permit means a municipal inspector will verify the work meets plumbing code, which protects you from shoddy work that could cause leaks, contamination, or gas hazards.

Work That Almost Always Requires a Permit

• Water heater installation or replacement (in nearly every jurisdiction)
• Repiping (partial or whole house)
• Sewer line repair or replacement
• Water line replacement
• Gas line work (any modification to gas piping)
• New plumbing for additions, remodels, or new construction
• Moving existing drain or supply lines to new locations
• Installing a new fixture in a location that did not previously have plumbing

Work That Typically Does Not Require a Permit

• Faucet repair or like-for-like replacement
• Toilet repair or like-for-like replacement (same location)
• Garbage disposal replacement
• Drain cleaning
• Fixing a leaking pipe (repair, not relocation)
• Replacing shut-off valves
• Water heater element or thermostat replacement (repair, not full unit replacement)

Why Permits Matter for Homeowners

Unpermitted work can cause serious problems when selling your home. A home inspection or title search may flag unpermitted plumbing work, and buyers or their lenders may require the work to be brought up to code before closing. If unpermitted plumbing work causes damage (a water heater installed incorrectly floods your home), your homeowners insurance may deny the claim.

Permit fees typically range from $50 to $300. This is a small cost relative to the protection it provides. A good plumber handles permits as part of the job. A plumber who suggests skipping the permit to save you money is cutting corners at your risk. Always ask: "Does this job require a permit? If so, are you pulling the permit and scheduling the inspection?"

How Can You Save Money on Plumbing Without Cutting Corners?

There are legitimate ways to reduce your plumbing bill by 15 to 30% without sacrificing quality or safety. The key is knowing which costs are negotiable and which shortcuts create bigger problems later.

Supply Your Own Fixtures

Plumbers mark up fixtures (faucets, toilets, garbage disposals, water heaters) by 20 to 40%. A toilet that costs $150 at a home improvement store may be quoted at $200 to $250 on the plumber's invoice. Buying the fixture yourself and paying labor-only for installation saves the markup. One caveat: some plumbers will not warranty a fixture they did not supply. Ask about this before buying. Also confirm the exact model with the plumber before purchasing to ensure compatibility.

Bundle Multiple Jobs Into One Visit

The service call fee ($75 to $150) is charged per visit, not per repair. If you have a dripping faucet, a running toilet, and a slow drain, scheduling all three in one visit saves you two service call fees ($150 to $300 in savings). Make a list of everything that needs attention before calling.

Ask If the Diagnostic Fee Applies to the Repair

Many companies charge $75 to $150 for a diagnostic visit but waive it if you hire them for the repair. This is common practice but not universal. Ask before they come out: "Is the service call fee applied toward the repair if I go with you?"

Get 3 Quotes for Any Job Over $500

This is the single most effective way to save money on plumbing. Quotes for the same job commonly vary 30 to 50%. Three quotes give you a clear picture of fair pricing and leverage to negotiate. For jobs under $300, one or two quotes is usually sufficient. For detailed guidance on evaluating plumbers, see our guide to finding a good plumber.

Ask About Repair Before Replacement

Some plumbers default to replacement because it is a bigger job with higher revenue. A faucet that drips may need a $20 cartridge, not a $300 new faucet. A toilet that runs may need a $5 flapper, not a $400 new toilet. Always ask: "Can this be repaired, or does it need to be replaced? What is the cost difference?" See when to call a plumber vs. DIY for repairs you can handle yourself.

Consider PEX Over Copper for Repiping

If your home needs repiping, PEX (cross-linked polyethylene, a flexible plastic pipe) costs 30 to 40% less than copper for materials and is faster to install due to fewer connections and flexible routing. PEX has been used in residential plumbing since the 1990s and has a strong track record. The main trade-off is that some homeowners and real estate markets still prefer copper. Both are solid choices for residential water supply lines.

Maintain Your Water Heater

An annual flush ($80 to $200 professionally, free if you do it yourself) removes sediment that reduces efficiency and shortens tank life. Replacing the anode rod every 3 to 5 years ($150 to $300 professionally) prevents the tank from rusting from the inside. These two maintenance tasks can extend a water heater's life from 8 to 12 years to 12 to 15+ years, delaying a $1,200 to $2,500 replacement. Use our water heater age decoder to check how old your unit is.

Skip the Camera Inspection You Do Not Need

Camera inspections ($100 to $350) are valuable for sewer line issues, recurring clogs, and pre-purchase home inspections. They are not necessary for a simple kitchen sink clog or a toilet repair. If a plumber recommends a camera for a straightforward job, ask why. A legitimate reason is identifying root intrusion or pipe damage causing recurring problems. An illegitimate reason is padding the bill.

How Much Does Plumbing Cost by Region in 2026?

Plumbing labor rates vary by 20 to 30% across the United States. Knowing your regional baseline helps you evaluate whether a quote is fair for your area, not just nationally. The ranges below reflect plumber hourly rates and typical project costs by region.

For pricing specific to your city, see our local plumbing cost guides: Philadelphia, Cincinnati, Nashville, Tampa, Seattle, and 30+ other cities.

What Happens If the Plumber Finds Additional Problems?

A reputable plumber stops work, explains what they found, and gives you an updated estimate before doing anything additional. They never perform extra work without your approval. This situation is more common than most homeowners expect because plumbing problems are often hidden behind walls, under floors, or inside pipe systems.

Why Discovery Issues Are Normal

A plumber who opens a wall to fix a leak may discover corroded pipes, improper previous repairs, or code violations that were not visible during the initial inspection. This is not unusual, especially in homes built before 1980 where galvanized pipes, outdated fittings, and previous DIY repairs are common.

The Right Process

The plumber should stop, show you the issue (photos or in person), explain the options, provide a revised estimate, and wait for your approval before continuing. For larger jobs (repiping, sewer work, bathroom remodel), any scope change should be documented in writing with a revised price before the additional work begins. Verbal agreements to "just fix it while you are in there" are how bills double without your clear understanding.

How to Tell If a Discovery Is Legitimate vs. an Upsell

Ask to see the problem. A legitimate issue is visible and explainable. Ask: "What happens if I do not address this right now? Can I get this fixed separately later?" If the answer is that it is a safety issue or will cause immediate further damage, addressing it now makes sense. If it is "recommended but not urgent," you can get a separate quote for it later.

Some plumbers use the access they already have to suggest additional work. This is sometimes legitimate: replacing a shut-off valve while the water is already off is genuinely cheaper now than as a separate call. And it is sometimes opportunistic: recommending a full repipe when you called about one leaky joint. The test is whether you would have sought this repair independently within the next six months.

What Warranty Should You Expect on Plumbing Work?

Every plumbing repair over $200 should include a warranty on both labor and parts. The length and terms vary by job type, but getting no warranty at all is a dealbreaker. A warranty means the plumber will return and fix the issue at no charge if something goes wrong within the covered period.

Standard Warranty Terms by Job Type

What the Warranty Should Cover

• Labor to return and fix the issue at no charge
• Replacement parts if the original parts fail within the warranty period
• A clear process for making a warranty claim (who to call, expected response time)

What the Warranty Typically Does Not Cover

• Damage caused by the homeowner (chemical drain cleaners corroding new pipes, for example)
• Pre-existing conditions not related to the repair
• Normal wear and tear after the warranty period ends
• Fixture warranties if the homeowner supplied the fixture (the plumber warranties their labor, the manufacturer warranties the fixture)

Red Flag Warranty Situations

• No warranty offered at all
• "We stand behind our work" without specific terms (what does that mean in practice?)
• Warranty voided if you do not use them for all future plumbing work
• Warranty requires annual paid inspections to remain valid

At minimum, get the warranty terms in writing on the invoice or quote. The document should state what is covered, how long the coverage lasts, and the process for making a claim. If the plumber will not put the warranty in writing, reconsider hiring them. For more on evaluating plumbing companies, see how to find a good plumber.

Common Plumbing Upsells: Legitimate vs. Questionable

Legitimate upsells (worth considering):

• Expansion tank with water heater ($50 to $150): required by code in most jurisdictions
• Sewer camera inspection during drain cleaning ($100 to $300): identifies root cause of recurring clogs
• Water heater drain pan ($20 to $50): catches leaks before they damage your floor
• Shut-off valve replacement during other work ($50 to $200): smart preventive maintenance

Questionable upsells (get a second opinion):

• Whole-house water treatment system during a simple repair ($2,000 to $5,000)
• "Your water heater is about to fail" during an unrelated service call
• Repiping the whole house when you called about one leaky pipe
• Expensive fixtures when standard ones would work fine
