Plumbing Service Agreement: How to Build and Sell One

Published on October 5, 2026 by Halo Programs

A plumbing service agreement is a paid, recurring plan in which a plumbing company inspects and maintains a home’s plumbing on a schedule, usually once or twice a year, and keeps the record of what it found. For the homeowner it is a way to have the water heater flushed, the shutoffs tested, and the pipes readied for winter without remembering to book any of it. For the plumbing company it is the product that turns an emergency call into a household that pays every year, opens the door every year, and already knows who to call when the water heater finally goes.

This guide is for owners and operations leads at plumbing companies who want to build a plumbing service agreement or repair one that exists on a brochure and not on the calendar. It covers what the plan includes, what it does and does not do for insurance claims and manufacturer warranties, how to price it, when to sell it, the cancellation and auto-renew rules that attach to it, and how to measure it. It explains the plan in homeowner terms along the way, because your technicians and office staff have to.

What a Plumbing Service Agreement Is

Remove the branding and every plumbing service agreement has the same four parts: scheduled visits, a defined scope of work at each visit, a written record of the home’s plumbing and equipment, and a membership term that renews. Companies sell it as a plumbing maintenance plan, a maintenance agreement, a service plan, a protection plan, or a club membership. The name matters less than whether all four parts exist. A plan missing any one of them is a discount card with a logo on it.

What the homeowner is buying

Homeowners do not buy inspections. They buy fewer surprises: no cold shower on a Monday, no ceiling stain under the upstairs bath, no burst hose bib in January. Most households have no idea how old the water heater is, where the main shutoff is, or what their water pressure reads, and they find out all three on the worst day to learn it. The plan sends a licensed plumber through the house on a schedule to answer those questions before anything fails, and it leaves a dated report behind.

What the plumbing company is building

The company is building a list of households that pay it every year, let it in the house every year, and have a documented reason to call it first. Plumbing has more planned work than its emergency reputation suggests: an annual water heater flush and anode check on tanks, annual descaling on tankless units in hard water, backflow assembly testing where the water purveyor requires it, pre-freeze winterization of hose bibs and exposed lines, a spring sump pump test, drain cleaning on a cadence for root-prone lines, and filter and softener service. A plumbing service agreement is the container that packages those visits into one contract, so they stop depending on the homeowner remembering your number.

It also changes what an emergency call is worth. The plumbing leads guide treats the emergency call as the acquisition moment in this trade, and the agreement is what that moment converts into. Without one, the household you rescued last winter calls whoever it finds first next time.

Why a Plumbing Service Agreement Pays the Company

Many plumbing companies treat the agreement as a courtesy or a way to hand out a discount. That undersells it. The membership fee is the smallest of the three revenue streams the plan produces.

Membership revenue

The fee pays for the visits. Priced correctly, covered in the pricing section below, it covers labor, materials, and the report with a margin. On its own it is a modest line. It is also the only revenue in plumbing that arrives on a known date whether or not anything froze, and visits scheduled in the shoulder seasons keep technicians billable in the weeks the phones are quiet.

Repair revenue found in the house

Every visit is a documented inspection by the company that will quote the fix. The corroded shutoff under the sink, the washing machine hose past its life, the pressure reading that explains the running toilets, the missing expansion tank: each is a repair ticket that exists because a plumber was in the house with a gauge and a camera. Members accept those quotes at a higher rate than strangers do, because the finding comes with a photo from someone they already pay to look.

Replacement revenue without a bid

The largest stream arrives later. Every water heater in the plan has an install date on file, and tank water heaters tend to reach the end of their service life around a decade in. A member whose tank is in year nine has heard from your company every year and has a report showing the sediment and the anode. The replacement is planned, priced in advance, and booked for a weekday, instead of sold at emergency rates to whoever answered the phone. Repipes on older galvanized or polybutylene lines follow the same path. The do plumbing contractors need a CRM guide makes the wider case for staying in contact through the quiet years. The plumbing service agreement is how a company does it and gets paid along the way. Where the agreement sits among the other growth levers is covered in how to grow a plumbing business.

A worked example of plumbing service agreement economics

The figures below are placeholders to show the arithmetic, not market rates. Replace them with your own.

• Base: 2,000 past customers in the database.
• Enrollment: 10 percent join over two years, so 200 members.
• Membership fee: $350 a year, so $70,000 in annual membership revenue.
• Repairs: if one member in three accepts a repair quote each year, about 65 repair tickets a year that no advertising produced.
• Replacements: across 200 homes with tank water heaters of mixed age and roughly a ten-year life, somewhere around 15 to 20 tanks a year reach replacement, and each one is a job the company is positioned to win before the homeowner searches for anyone.

Run your own average repair ticket and average water heater install through those counts. For most companies the replacement line alone outweighs the membership fee, which is why the fee should be priced to cover the visits and never discounted to zero to win enrollments.

What to Include in a Plumbing Service Agreement

Scope is where a plumbing service agreement is won or lost. A vague scope (“annual plumbing check”) invites disputes and gives the homeowner nothing to picture. A scope that promises too much turns the plan into an open-ended repair obligation. Write it as a list of tasks with limits.

The core visit

• Water heater service: flush sediment from a tank, check the anode rod, test the temperature and pressure relief valve, check the expansion tank and the venting on gas units, and record the make, model, serial number, and install date.
• Water pressure: a static pressure reading at a hose bib, and a check of the pressure reducing valve if the home has one.
• Main shutoff: locate it, operate it, tag it, and show the homeowner where it is.
• Fixture shutoffs and supply lines: every sink, toilet, and appliance connection, including washing machine hoses and the ice maker line.
• Toilets and faucets: a dye test on each toilet and a check for drips and loose fixtures.
• Visible drains and traps: under every sink, plus a flow check on tubs and showers.
• Exposed piping: the crawl space, basement, or garage run, noting pipe material and any corrosion or prior repairs.
• A dated report with photos and findings sorted into “fixed today”, “recommend repair”, and “monitor”.

Minor repairs, with a written limit

Members expect small fixes to be included. Define them precisely: replacing a stated number of toilet flappers or fill valves, tightening or reseating loose fixtures, replacing a stated number of supply lines from truck stock, clearing one slow sink trap. Anything beyond the limit is quoted as a repair at the member rate. The limit protects the company, and it also protects the homeowner from believing the plan covers work it does not.

Add-ons that belong in the plan

• Winterization before the first freeze: hose bibs, exposed lines, and an irrigation blow-out where the home has a system, with a spring start-up to match.
• Backflow assembly testing where the water purveyor requires it. In Washington, for example, WAC 246-290-490(7) requires assemblies to be tested when installed and annually after that, and other states set their own schedules. States and purveyors also decide who is certified to perform the test, so confirm both before printing it in the plan.
• Tankless descaling once a year in hard water areas, in place of the tank flush.
• Sump pump test in spring, including the float, the check valve, and the discharge line.
• Drain maintenance on a cadence for homes with root-prone lines, with a camera inspection at a member price.
• Filter and softener service on the cartridge schedule the equipment calls for.
• Priority emergency scheduling, meaning members go to the front of the queue when every plumber in town is booked. Promise the place in line, not a number of minutes.

A water heater maintenance plan sold on its own, one flush and inspection a year, is a reasonable entry product for a customer who has just had a tank installed and is not ready for the whole-home version.

Three tiers of a plumbing service agreement

Tiers make the decision easier for the homeowner and raise the average fee. A common structure:

• Essential: one annual whole-home inspection with water heater service and a written report, plus the member repair rate.
• Standard: the annual inspection, a second visit for fall winterization, the minor repair allowance, and priority emergency scheduling.
• Premium: everything in Standard plus the add-on the home needs (backflow testing, tankless descaling, sump service, or drain maintenance), a larger repair allowance, and member pricing on water heater replacement.

Keep it to three. A fourth tier adds a comparison chart the homeowner has to study, and a plan that needs studying does not get bought at the kitchen table.

The Plumbing Maintenance Plan Visit, Step by Step

The visit is the product. A plumbing maintenance plan that runs rushed, undocumented visits teaches members to see it as a water heater flush with a surcharge, and they cancel at renewal. The visit should follow the same sequence every time.

1. Confirm the appointment two to three days ahead and the morning of, including access to the water heater, the crawl space, and the main shutoff.
2. Ask before you look. Slow drains, noises, a spike in the water bill, a fixture the homeowner has stopped using: a two-minute conversation points the inspection.
3. Read the pressure first. The number explains much of what the rest of the visit will find.
4. Operate the main shutoff and tag it. If it will not turn or will not hold, that is the first finding on the report.
5. Service the water heater and photograph the rating plate, the anode, and anything corroded.
6. Walk the fixtures in a fixed order, top floor to bottom, then the exterior. The same order every year is what makes one report comparable to the next.
7. Do the included repairs and photograph before and after.
8. Deliver the report the same day, with photos, the “recommend repair” list priced, and the water heater’s age noted against its warranty term.

One rule belongs in technician training: if a water heater problem looks like a defect in the unit and the unit is inside its warranty period, document it and tell the homeowner how the manufacturer’s claim process works before replacing anything. The warranty section below explains why.

Insurance, Warranties, and the Plumbing Service Agreement Record

The strongest selling point of a plumbing service agreement is also the easiest to overstate. The plan does not make an insurer pay and does not extend a manufacturer’s warranty. What it does is create a dated record that both of those processes lean on. Teach your team the difference, because a technician who promises the first will produce a complaint, and one who explains the second will produce a member. This is not legal or insurance advice; policies and warranties vary.

What homeowners insurance says about water

Insurers build most homeowners policies from standard forms. The ISO HO 00 03 homeowners form, whose sample the Insurance Information Institute publishes, shows where plumbing maintenance and coverage meet:

• Freezing. The form does not insure loss caused by freezing of a plumbing system, or by leakage from the system caused by freezing, unless the insured used reasonable care to maintain heat in the building or to shut off the water supply and drain all systems and appliances of water.
• Wear and corrosion. The dwelling coverage excludes loss caused by “wear and tear, marring, deterioration”, by mechanical breakdown, and by rust or other corrosion.
• Sewer backup and sumps. The water damage exclusion reaches water that backs up through sewers or drains or overflows from a sump or sump pump. Under the base form that loss is excluded, which is why homeowners who have that protection hold it as an addition to the policy.
• Duties after a loss. The insured must protect the property from further damage, make reasonable and necessary repairs to protect it, and keep an accurate record of repair expenses.

Read that list as a plumbing company. The freezing condition describes a winterization visit almost word for word, and it matters most for second homes and for owners who travel in winter. The wear and corrosion exclusions are the reason a slow failure is the homeowner’s bill, and catching slow failures is what the annual inspection is for. The sump exclusion is a reason to test the pump every spring and to suggest the homeowner ask their agent what the policy says about backup. The Insurance Information Institute reports that water damage and freezing produced about 1.5 claims per 100 insured house-years from 2019 to 2023, at an average of roughly $15,400 a claim, so none of this is a rare event. A plumbing service agreement cannot decide a claim. A dated report showing the shutoff tested, the lines winterized, and the water heater in sound condition gives the homeowner more than memory to point to.

What a water heater warranty asks of the owner

Manufacturer warranties differ, so train on the brands you install. Bradford White’s published warranty information is a useful example of what a service record supports:

• The limited warranty applies when the product is used, installed, and maintained in accordance with the installation and operation instructions and the warranty terms packaged with the unit.
• The warranty begins at the date of installation, and proof of installation may be required. Registration records the owner, the installing contractor, and the install date.
• Residential warranty duration assumes the unit is installed in a single-family dwelling; other uses shorten it.
• Standard residential models carry 6-year or 10-year tank warranties, and the manufacturer’s extended warranty upgrade has to be registered within 60 days of its purchase or no more than six months after the original installation date.

Three things follow for a company running a plan. The agreement’s equipment record, with the serial number, install date, and a service entry each year, is the proof a warranty claim asks for, and most homeowners cannot produce it. A technician who finds a possible defect inside the warranty term should document it and walk the homeowner through the manufacturer’s process, not swap the tank and discard the evidence. And the six-month window on an extended warranty means the offer belongs at installation, in the same conversation as the plan.

How to Price a Plumbing Service Agreement

Price the plumbing service agreement from cost, then check it against what the homeowner will accept. Pricing from a competitor’s flyer is how companies end up subsidizing every visit.

Build the per-visit cost

Add up what one visit takes, including drive time and the report. Using placeholder numbers: one technician spending 1.5 hours including drive, at a loaded labor cost of $55 an hour, is $82.50. Add $12 of flappers, supply lines, and washers for the minor repair allowance, and $10 of office time to finalize and send the report. One visit costs about $105, and two visits cost $210 a year.

Set the margin and the price

Divide annual cost by one minus the target gross margin. At a 40 percent margin, $210 divided by 0.60 is $350 a year, or about $29 a month. Price the Essential tier from one visit the same way, and the Premium tier from two visits plus the cost of the add-on, including any test filing fee the purveyor charges for backflow reports.

Adjust for the house, not the homeowner

Bathroom count, the number of water heaters, tank versus tankless, and crawl space access change the labor. Rather than quoting every home, set two or three bands (for example by number of bathrooms) with a surcharge for a second water heater. The homeowner sees a clear rule, and the technician is not losing an afternoon on a five-bath house priced like a condo.

Annual or monthly billing

Monthly billing lowers the sticker and raises enrollment, and it also creates a recurring card charge that brings in the automatic renewal rules covered below. Annual billing is simpler to administer and makes renewal a yearly decision. Either works. What does not work is billing monthly without the disclosures, consent, and cancellation path the law requires.

How to Sell a Plumbing Service Agreement

A plumbing service agreement sells at moments when the homeowner is already thinking about the plumbing. Build the offer into those moments rather than running it as a standalone campaign.

After the emergency, not during it

The emergency call is the largest source of new members and the easiest one to mishandle. A homeowner standing in an inch of water is not a prospect. Fix the problem, show what you found, and present the plan once the water is off the floor, or in the follow-up that goes out that week with the summary of the visit. The pitch is specific to the house: the tank is nine years old, the pressure reads high, the main shutoff took two hands. The plan is the answer to a report the homeowner has just read.

At a water heater installation

The install is the one planned meeting every water heater customer attends. Present the plan with the warranty paperwork: the manufacturer wants the unit maintained to its instructions and may ask for proof of the install date, and the plan keeps that record and performs that maintenance. Offer the first year at an installation price and set the renewal date in a slow month.

At any planned service call

A homeowner paying for a one-off drain cleaning, backflow test, or winterization has just learned what a visit costs. Show the Standard tier next to that invoice. A known annual price that includes the visit they just bought is an easy comparison while the bill is still on the counter.

To past customers, unsold estimates, and new owners

The database holds three more audiences. Past emergency customers from before the plan existed are the largest, and a note built around the age of their water heater reaches them with a reason. Unsold repair estimates are the second, because a homeowner who declined a repair may accept a plan that monitors the problem. New owners are the third: a household that just bought a home your company has serviced inherited a water heater and a main shutoff it knows nothing about, and you hold the file. A plumbing newsletter is the channel that keeps all three hearing from you between offers, and it gives members a reason to renew. The plumbing marketing guide places these audiences inside the full marketing plan.

The cancellation notice most plumbing companies miss

The FTC’s Cooling-Off Rule, 16 CFR Part 429, covers sales of $25 or more made at the buyer’s residence. A visit the homeowner requested for a repair or maintenance is outside it, but the exclusion ends there: anything additional sold during that visit is not excluded. A plumbing service agreement signed at the kitchen table during a repair call is therefore generally a covered sale. The homeowner has three business days to cancel, and the company has to hand over a Notice of Cancellation in duplicate with the required statement in 10 point bold face type. Sundays and federal holidays do not count as business days. Put the notice in the sign-up packet or the e-signature flow so it happens on every sale without a technician having to remember it, and have counsel confirm how your state’s home solicitation law adds to it.

What not to promise

• No “covers your plumbing”. A plan that promises to pay for repairs or replacements when things fail, rather than to perform defined maintenance, starts to resemble a service contract or home warranty, which many states regulate separately. The name “protection plan” leans in that direction, so if you use it, make the scope page say plainly what is maintained and what is not covered. Have counsel read the contract.
• No “extends your warranty”. The manufacturer’s terms do not change because a homeowner joined a plan.
• No “insurance will pay”. The record helps a claim. It does not decide one.
• No response-time clock. “Members are scheduled first” is a promise the company controls. “A plumber within the hour” is one a freeze week will break.

Renewal and Auto-Renew Rules for a Plumbing Service Agreement

A plumbing service agreement that renews automatically is a subscription in the eyes of the law, and subscription rules have tightened. Build compliance into sign-up rather than retrofitting it after the first cancellation complaint.

California’s automatic renewal law

California’s Automatic Renewal Law, Business and Professions Code 17600 and following, was amended by AB 2863, with the changes applying to contracts entered into, amended, or extended on or after July 1, 2025. For a company selling an auto-renewing plan to California homeowners, Section 17602 requires the renewal terms to be presented clearly and conspicuously before the subscription is fulfilled and in visual proximity to the request for consent; the consumer’s express affirmative consent before charging; for an annual plan, a yearly reminder in the same medium the consumer signed up in, stating the service, the frequency and amount of charges, and how to cancel; notice of a price change no less than 7 and no more than 30 days before it takes effect; and, for a consumer who signed up online, a way to cancel online at will through a prominently located link or button. Several other states have their own automatic renewal statutes, so check the states where your company works.

Federal rules: ROSCA and the vacated click-to-cancel rule

For plans sold online, the federal Restore Online Shoppers’ Confidence Act (15 U.S.C. 8403) requires a negative option offer to clearly and conspicuously disclose all material terms before collecting billing information, to obtain the consumer’s express informed consent before charging, and to provide simple mechanisms to stop recurring charges. The FTC’s broader 2024 “click-to-cancel” amendments to its Negative Option Rule were vacated by the Eighth Circuit on July 8, 2025, in Custom Communications, Inc. v. FTC, on procedural grounds. The FTC restarted the process with an advance notice of proposed rulemaking announced March 11, 2026. The practical answer for a plumbing company does not depend on how that ends: make the terms clear, get the consent in writing or by an affirmative click, send the annual reminder, and make cancelling as easy as joining.

The 540-day calling window

Renewals also affect who the company may call. Under the FTC’s Telemarketing Sales Rule, an established business relationship lets a company call a number on the National Do Not Call Registry for 540 days after a purchase, unless the person has asked that company specifically not to call. An annual membership payment is a purchase, so a member who renews every year never leaves that window, and a member who lapses stays callable for 540 days after the last payment. A household whose burst pipe you fixed three winters ago and never enrolled is outside it. That difference is the renewal call’s legal footing; the company-specific do-not-call request always overrides it.

Measuring a Plumbing Service Agreement

Membership count is the number everyone watches and the least useful one on its own. Track six.

• Emergency-to-agreement conversion. Of the new households served on an emergency call this quarter, how many joined within 30 days. This measures the follow-up, and it is the number that decides how fast the plan grows.
• Enrollment rate at water heater installs. This measures the pitch and the paperwork.
• Renewal rate. Of members up for renewal, how many renewed. This measures the visits. A falling renewal rate almost always traces back to rushed or late visits and thin reports.
• Visits completed in their season. Winterization done before the first freeze, sump tests done before spring rain. A plan whose visits slip becomes a plan members cancel.
• Repair revenue per member. Repairs quoted and accepted from findings, divided by members.
• Water heater replacements sold to members. And, more telling, the share of member replacements that were planned versus emergency. In a working plumbing service agreement, a member’s tank should almost never fail as a surprise.

Where ContractorHalo Fits in a Plumbing Service Agreement

A plumbing service agreement has two halves. One is operational: scheduling the visit, dispatching the technician, charging the membership fee, and invoicing the repair. That work belongs to the field service platform your company runs, and those platforms handle it well. ServiceTitan describes service agreement automation, Housecall Pro can add a membership plan to an estimate and auto-charge plan members, and FieldEdge keeps service agreement history on the customer record. The plumbing software vs plumbing CRM guide explains where that layer ends. ContractorHalo does not dispatch technicians or send invoices.

The other half is the relationship, and that is what ContractorHalo is for. It is a CRM built for residential contractors and run as a done-for-you program. The CRM holds every property, member, equipment age, and contact in one dashboard and lets your team text customers one-to-one. The automated marketing program sends maintenance reminder emails, service reminder postcards, thank-you cards, and satisfaction surveys from that same database, so the winterization reminder, the post-visit thank-you, and the survey that tells you whether renewals are at risk go out without anyone remembering to send them. The same database drives the offers to past emergency customers, unsold estimates, and new owners that fill the plan, and co-op marketing lets you split the cost of those campaigns with manufacturers and distributors.

The plumbing CRM software buyer’s guide lists the records and renewal capabilities a system needs to run recurring service, and roofing companies building the same product will find the equivalent playbook in the roofing maintenance program guide.

Frequently Asked Questions

Conclusion

A plumbing service agreement is the product that turns a plumbing company’s emergency customers into households it serves every year. Build it from four parts, scheduled visits, a defined scope with a written repair limit, a dated equipment record, and a renewing term, and price it from cost so the fee pays for the visits. The larger return comes later, in repairs found in the house and in water heaters replaced on a weekday instead of in a flood.

Offer it after the emergency is fixed and at every installation, explain the record without promising what insurers or manufacturers will do, hand over the cancellation notice at the kitchen table, and keep the renewal compliant from the first sign-up. Then measure renewals and on-time visits as closely as enrollments, because a plan that slips its visits is a plan members cancel. The what is a plumbing CRM guide covers the system that holds the member records, and the reminders around every visit can run without your team sending a single one by hand.
