What a termite treatment guarantee should actually cover

Learn what termite treatment guarantees actually cover, what conditions void them, and how to compare terms across specialists fairly.

You've noticed mud tubes on your foundation or spongy wood in a beam, and a pest control specialist has been out to assess. Now they're quoting you a price and promising a guarantee. Before you sign, you need to know what that guarantee actually protects you against—and what gaps might leave you exposed to re-infestation or hidden damage.

A termite treatment guarantee is not a simple all-or-nothing promise. It's a conditional contract that covers specific treatments under specific conditions, and the details matter more than the headline number. Understanding what you're actually buying helps you compare quotes fairly and avoid nasty surprises later.

What the guarantee does and doesn't cover

A solid termite treatment guarantee typically covers the cost of retreatment if termites return to the treated area during the guarantee period—usually one to five years, depending on the specialist and treatment type. This means if mud tubes reappear or inspection reveals active colonies in zones the specialist treated, they'll come back and retreat at no extra charge.

What it usually does *not* cover is damage that happened before or during the initial treatment. If termites have already weakened timber, the guarantee doesn't pay for repairs. It also rarely covers damage occurring outside the treated zone—for instance, if treatment protects the perimeter but termites find their way into an attic or extension that wasn't part of the plan. Some guarantees exclude areas the specialist flagged as inaccessible or unsuitable for treatment. Others won't honour the guarantee if you've failed to maintain the treated barrier or if new timber or extensions have been added without retreatment.

Read the fine print carefully. Ask the specialist to walk you through what's in and out of scope, and get it in writing.

The conditions that can void or weaken your guarantee

Most guarantees come with strings attached. Common conditions include:

Annual inspections – You may need to have the specialist inspect annually to keep the guarantee valid. Some providers allow you to do visual checks yourself, but confirm this in writing.
No structural changes – If you renovate, add an extension, or expose new timber, the old guarantee may no longer apply to those areas.
Barrier maintenance – If the treatment relies on a chemical barrier in the soil, the guarantee often assumes you won't dig or build over it in ways that breach it.
Contractor access – The specialist needs permission to inspect and retreat if needed. If you block access or restrict their ability to monitor, they may refuse to honour the guarantee.
Honest reporting – If you claim you've spotted termites but haven't actually had them assessed independently, or if you've already hired another pest controller without telling the first one, that can invalidate coverage.

Before committing, ask what happens if any of these conditions shift. Some specialists will renegotiate; others will void the guarantee outright.

Comparing guarantees across quotes

When you're weighing multiple quotes, don't just look at the headline price and the year number. Compare:

Length of guarantee – Five years is longer than three, but is it necessary for your situation? Ask if the duration ties to the treatment method (soil barriers often last longer than timber treatments).
Scope of coverage – Does it cover the full property or only the treated zone? Are outbuildings included?
Re-treatment costs – Does the guarantee mean unlimited retreatment, or does it cap the number of visits?
Inspection requirements – Will annual inspections cost extra? Who bears the cost?
Insurance backing – Some specialists carry professional indemnity insurance that backs their guarantee. Ask if the guarantee is insurable.

A longer or broader guarantee sounds safer, but it should reflect fair pricing. A suspiciously cheap quote with a five-year promise may mean the specialist is cutting corners or relying on conditions that make the guarantee hard to claim.

Once you've narrowed down your options, ask each specialist to send their guarantee terms before you book. Many will provide a template, and you can compare them side by side. When you're ready to move forward, use a platform like Strove to find verified termite specialists in your area and read what past clients have said about their follow-through on guarantees.

Common questions

If termites come back after treatment, will my guarantee cover the cost of fixing the damage?: No. A treatment guarantee covers the cost of retreatment if termites return to the treated zone, but not the cost of repairing timber or structural damage. Damage assessment and repairs are separate services you'd need to arrange independently. It's why asking the specialist about existing damage before treatment starts is important—once they've treated, damage claims become harder to prove.
What happens to my guarantee if I move house or sell the property?: Most guarantees are tied to the property and the owner at the time of treatment, not to subsequent occupants. Check the terms: some specialists will transfer the guarantee to a new owner if the property is sold, while others void it. This is worth asking before treatment, especially if you might sell soon.
Can I do my own annual inspections to keep the guarantee valid, or do I have to use the specialist?: It depends on the guarantee terms. Some specialists require their own annual inspection to validate the guarantee; others permit you to do visual checks for signs of activity (mud tubes, damaged wood) and report back. Always clarify this in writing before signing, because getting it wrong could void your coverage without you realising it.
If I renovate and add new timber to my house, will the original guarantee still cover it?: Usually not. Renovations and new structures often sit outside the original treatment zone and barrier. You'll need to discuss whether the specialist will extend treatment to new areas—this typically costs extra—or whether you'll need a separate guarantee for the new work.
