Two termite warranties can sound identical and cover completely different things. Here's how to read one — and the retreatment-vs-repair distinction that matters most.
After a termite treatment, most companies hand you a warranty — and most homeowners file it without reading it closely. That's a mistake, because two warranties that sound alike can cover very different things. The single most important distinction is whether the warranty covers *retreatment* only, or retreatment *and* repair. Here's how to actually read one.
The Distinction That Matters Most: Retreatment vs. Repair
| Coverage type | What it covers | What it doesn't |
|---|---|---|
| Retreatment warranty | If termites come back, they re-treat at no charge | Does not pay to repair any new damage |
| Repair warranty | Retreatment *plus* repair of new termite damage | Usually stricter conditions and higher cost |
Most standard termite warranties are retreatment warranties — if activity returns in the covered area, the company treats it again for free. That's valuable, but it's not the same as covering the *damage* new termites cause. Repair warranties exist but are less common and come with more conditions. When you're comparing companies, "we guarantee our work" can mean either one — so ask which.
Limited vs. Renewable (Annual) Warranties
Warranties also differ in duration and structure:
- Limited warranty — covers a set period after treatment (e.g., a year or a few years), often included with the treatment.
- Renewable / annual warranty — you pay a modest annual fee (usually tied to a yearly inspection) to keep coverage going. This is common for subterranean barrier treatments, where ongoing protection depends on the barrier being maintained and monitored.
Renewable coverage is often the better long-term value, because termite pressure doesn't end after one treatment — it's why annual inspections matter regardless.
What Voids a Warranty
Warranties have conditions, and it's worth knowing them before you unknowingly break one:
- Conducive conditions left unaddressed — leaks, earth-to-wood contact, or moisture problems the report flagged as Section 2 items. Leave them, and a claim can be denied.
- Missed renewals or inspections — let an annual warranty lapse and coverage ends.
- Alterations — some construction or landscaping changes near the treated area can affect coverage.
- New, unrelated infestations outside the treated scope.
Fumigation vs. Subterranean Warranties Work Differently
The warranty structure tends to follow the treatment. A tent fumigation kills everything currently in the structure but leaves no lasting barrier, so its warranty is time-limited and is really about whether the treatment was fully effective. A subterranean Termidor barrier, by contrast, provides ongoing protection, so its warranty is usually the renewable, annually-inspected kind. Neither treatment prevents a brand-new colony from starting later — which is the honest reason ongoing inspection is part of any real protection. Our post on how long termite treatment lasts covers that durability question in depth.
Questions to Ask Before You Sign
- Is this retreatment-only, or does it cover repair too?
- How long does it last, and is it renewable?
- What conditions would void it?
- Does it require an annual inspection to stay active?
- Is the coverage tied to the specific treated area or the whole structure?
The Bottom Line
A warranty is part of the value you're buying, not an afterthought — read it with the same attention you gave the quote. The key is knowing exactly what "guaranteed" means in your contract: what's covered, for how long, and what keeps it in force. When you get an inspection with us, we'll walk through the warranty that applies to the recommended treatment so there are no surprises later.
