How Home Warranty Plumbing Claims Actually Work
We're a service contractor for several home warranty companies, and we do this work every day. This page explains the process in plain English — because most of the frustration we see comes from nobody ever explaining it.

If your warranty company sent us to your house, this page is for you.
Who's who
There are three parties, and it helps to know which one does what.
You hold a contract with a home warranty company.
The warranty company — American Home Shield, 2-10, HWA, First American and others — decides what your contract covers and authorizes what gets paid for.
We are the licensed plumber they dispatch to your house. We diagnose the problem, report what we found, and do the work that gets authorized.
Here's the part that surprises people: we don't decide what's covered. We report the facts to your warranty company, and they make the coverage decision against your contract. When we tell you we're waiting on authorization, we're genuinely waiting.
The normal sequence
- You open a claim with your warranty company and pay your trade service fee to them.
- They dispatch us, and our office contacts you to schedule.
- We come out and diagnose. This is a real diagnostic visit — we find out what failed and why.
- We report to your warranty company. What failed, the cause, what it takes to fix.
- They make a coverage decision and authorize what your contract covers.
- We complete the covered work. If parts have to be ordered, there's a second visit.
- Anything not covered is quoted to you separately, and you decide.
Steps 4 and 5 are where the waiting happens. Sometimes it's the same visit. Sometimes it takes longer, especially if equipment has to be ordered through the warranty company's own supplier.
"Non-covered charges" — what that actually means
This is the single biggest source of confusion, so here it is plainly.
Your warranty covers the repair or replacement of the failed item, subject to the terms of your specific contract. It generally does not cover everything that has to happen around that repair. Depending on the contract, items commonly not covered include things like permits, bringing existing conditions up to current code, modifications needed to fit new equipment, disposal, and access work.
That's why you can have a fully covered water heater and still owe money. It isn't a contractor making up charges, and it isn't your warranty company being difficult — it's the line every contract draws between the failed part and the work surrounding it.
What you should expect from us: any amount you would owe is explained and priced for you before we do that work. You approve it or you don't. Nobody should ever be surprised by a bill at the end.
Coverage depends on your contract, not on general rules
Every provider writes more than one contract, and the same item can be covered differently depending on which one you have — a plan bought directly by a homeowner is often not the same as one that came with a real estate transaction, and optional coverage changes the picture again.
So when someone on the internet tells you "warranties always cover X" or "they never cover Y," ignore it. Your contract is the answer. Ask your warranty company for your coverage documents and read the section for the item that failed. If you want, ask us what we reported to them — we'll tell you.
How long the work is warrantied
On a home warranty job, the warranty period is set by your warranty company, not by us. Every plan has its own recall window and its own rules about what happens if the same problem comes back. If you want to know how long you are covered on a warranty repair, your plan is the one that decides it — ask them, and they will tell you.
On work you pay us for directly, retail or commercial, our workmanship is warrantied for one year. That is our own commitment and it has nothing to do with any warranty company.
How to make your claim go faster
Be specific when you open the claim. "No hot water, gas heater, water on the floor" gets a better-prepared plumber than "water heater problem."
Say if there are access issues. A heater in a crawlspace, a finished wall in front of a cleanout, a locked gate, a dog. Access surprises turn one visit into two.
Be reachable. Authorizations and parts updates move fast, and claims stall when nobody can reach the homeowner.
Keep your paperwork. Your contract number and your coverage documents answer most questions immediately.
Ask us what we found. You're entitled to know what we reported. We'll explain it.

I was sent to you by my home warranty. Will you charge me a trip charge?
No. Mayes doesn't charge a trip charge on home warranty calls — not on any of them, from any warranty company. If there's a service fee on that call, it's your warranty plan's own fee, set by your plan.
Why do I owe money if I have a home warranty?
Because a warranty covers the failed item under the terms of your contract, and generally not everything around it — things like permits, code upgrades, modifications and disposal are commonly excluded. Whatever you'd owe is explained and priced before that work is done.
Who decides if my repair is covered — you or the warranty company?
The warranty company. We diagnose and report; they make the coverage decision against your contract.
How long does authorization take?
It varies. Sometimes it's resolved on the first visit. Larger jobs and anything needing equipment ordered through the warranty company take longer. We'll tell you where your claim stands whenever you ask.
Can I just pay you directly instead of using my warranty?
Yes. Plenty of customers decide the deductible and the wait aren't worth it for a smaller job. We're happy to do the work as a regular retail call.
Why does a second visit happen?
Almost always parts. When equipment has to be ordered — often through the warranty company's own supply channel — we come back once it's here.
