Most plumbing businesses live and die by the next service call. Something breaks, a customer calls, you fix it. Then they forget you exist until something breaks again. Service agreements flip that model. Instead of chasing jobs, you've got a list of customers who pay you every year whether something breaks or not -- and who call you first when it does.

The Quick Answer

A plumbing service agreement is an annual plan where customers pay a flat fee for regular inspections, priority scheduling, and repair discounts. Typical pricing by tier:

Bronze (entry): $150-250 per year -- one annual inspection, 10% repair discount
Silver (mid-tier): $200-300 per year -- two visits, priority scheduling, 10-15% discount
Gold/Platinum: $300-500 per year -- two visits, water heater flush, camera inspection, waived trip fees, 15% discount

A shop with 250 agreements at $250/year generates $62,500 in recurring annual revenue before a single repair call. And those agreement customers call you first for repairs.

Why Retention Rates Matter So Much

Transactional plumbing businesses -- the ones without service agreements -- retain 40-60% of customers year to year. That means nearly half their revenue base disappears and needs to be replaced with new customers. Customer acquisition is expensive.

Shops with a structured service agreement program and 20%+ membership penetration achieve 70-85% annual renewal rates. Elite operators hit 90%. That's a stable, predictable base that compounds over time.

It also affects your company's valuation. Private equity and strategic buyers model plumbing service agreement books like SaaS assets -- 1.5-2.5x annual recurring revenue. A mature book of $100,000 in ARR could add $150,000-250,000 to what your business is worth. That's not hypothetical. PE firms in the trades specifically ask for this number when evaluating acquisitions.

How to Structure a 3-Tier Plan

The Good-Better-Best framework works because it gives customers a choice instead of a yes-or-no decision. Most will pick the middle tier, which is fine -- that's where you want them.

Tier 1: Bronze

Price: $150-250/year. What's included:

One annual plumbing inspection (water pressure check, fixture inspection, pipe check)
10% discount on all repairs booked through the plan
Reduced trip fee (waived or discounted)

This tier is the entry point. It's easy to say yes to because the price feels low compared to a single emergency repair call. That's the point.

Tier 2: Silver

Price: $200-300/year. What's included:

Two annual inspection visits
Priority scheduling -- moved to the front of the line on service calls
10-15% discount on repairs and replacements
Waived trip fee

Silver is your workhorse tier. Most customers who engage seriously will land here. Priority scheduling is the big sell -- nobody wants to wait 3 days for a plumber when a toilet is broken.

Tier 3: Gold or Platinum

Price: $300-500/year. What's included:

Two visits including water heater flush and drain camera inspection
Priority same-day scheduling
15% discount on all repairs
Waived trip fee plus an annual credit toward parts

Gold attracts homeowners with older systems or higher anxiety about plumbing failures. Position it as the plan for "houses that can't afford surprises." The camera inspection alone sells it -- customers love seeing inside their pipes.

What to Include in Every Tier

Regardless of tier, every plan should cover these basics at a minimum during inspection visits:

Water pressure test (optimal range 40-80 PSI)
Visual pipe inspection for corrosion or leaks
Fixture check (faucets, toilets, shut-off valves)
Water heater inspection (check anode rod, sediment level)
Drain function check

The inspection creates natural upsell opportunities. You find a failing anode rod and the customer agrees to a water heater flush while you're there. You spot a slow-draining tub and they add a drain cleaning to the visit. Agreement customers are already in a relationship with you -- they're far easier to upsell than cold callers.

How to Sell Agreements on Service Calls

The best time to pitch a service agreement is at the end of a completed service call, not the beginning. Finish the job. Solve their problem. Then bring it up.

Here's a simple script: "Everything looks good. I do want to mention -- we have a maintenance plan that would cover this inspection visit and give you priority scheduling if anything comes up. It's $[price] a year. A lot of our customers find it pays for itself with the first repair call. Want me to grab you the details?"

Keep it soft. You're not closing a sale, you're offering a resource. Customers who just had a stressful repair are receptive to the idea of preventing the next one. Strike while they're reminded of how much a bad plumbing day costs.

Also follow up. Send a simple email 3-7 days after a repair call that mentions the plan. Most customers don't decide on the spot. A short, friendly follow-up message catches the ones who needed a day to think about it.

Bottom Line

Service agreements turn one-time customers into recurring revenue. A good 3-tier structure, priced at $150-500/year, earns 70-90% annual renewal rates and compounds year over year. It's one of the highest-leverage things a plumbing business can build.
