Building a new home is thrilling. Somewhere between choosing cabinets and picking a paint color, though, one crucial step often gets overlooked: confirming what protection is already built into your foundation. Termite pretreatment for new construction is supposed to happen before the slab is poured or the crawlspace is closed up, typically as part of a broader termite treatment plan for the property. But treatment alone isn't proof. What you actually need is documentation — real paperwork that shows the work was done, done correctly, and done by someone qualified. Below is exactly what to ask your builder for, and why each document earns its place in your closing folder.
The Treatment Certificate: Your First Line Of Proof
Start here, because this is the foundation everything else builds on. A proper termite pretreatment for new construction should come with a signed certificate. That certificate needs to name the exact termiticide used, the date it was applied, and the license number of the applicator who did the work. Without those three details, you're really just taking someone's word for it. Furthermore, a license number lets you verify credentials with the state if you ever need to. So ask for the certificate before closing, not after. If your builder can't produce one, that's a red flag worth raising immediately, and it's worth pushing on until you get a straight answer.
The Application Diagram: Where Was The Barrier Actually Placed?
Next, ask for a diagram or graph showing where the treatment was applied around the foundation. A termiticide barrier only protects where it's actually placed. Consequently, gaps in coverage — around plumbing penetrations, porch slabs, or additions — leave an opening termites can exploit later. A proper diagram marks these areas clearly, so you, or a future inspector, know exactly what was covered and what wasn't. Additionally, that diagram becomes useful reference material down the road, especially if you ever schedule a professional termite inspection to confirm the barrier is still intact.
Warranty And Bond Paperwork: Check What Actually Transfers
Many pretreatments include a renewable warranty or bond from the company that applied it. That's good news, but only if you understand the terms. Ask specifically whether the warranty transfers to future owners, since this detail matters enormously if you sell the home down the line. A transferable warranty adds real value at resale. Meanwhile, a warranty that doesn't transfer is worth far less than it initially sounds, no matter how reassuring the paperwork looks. Also confirm the renewal schedule and cost, because most warranties require periodic reinspection and renewal fees to stay active. Skipping a renewal can quietly void your coverage without anyone telling you, so put the renewal date somewhere you'll actually see it.
Post-Construction Inspection: Confirm It Actually Happened
Finally, ask whether your local jurisdiction requires a post-construction inspection, and get confirmation it took place. Construction work after the initial treatment — digging for utilities, pouring additional concrete, grading the yard — can disturb or break the chemical barrier. Therefore, a follow-up inspection confirms the barrier wasn't compromised while the rest of the house went up around it. This step is easy to overlook once framing starts and everyone's attention shifts to the next phase. Still, it's one of the most important checks you can request, since it confirms your protection is still working on the day you move in.
Here's a quick side-by-side of what to request and why it matters:
| Document To Request | Why It Matters |
|---|---|
| Treatment certificate (chemical, date, applicator license) | Proves the treatment actually happened, and confirms exactly who performed it |
| Application diagram or graph | Shows exactly where the barrier covers your foundation, and where gaps might remain |
| Warranty or bond paperwork | Confirms renewable coverage terms, plus whether it transfers to you as a future seller |
| Post-construction inspection report | Confirms the barrier wasn't compromised during later construction work |
Why This Paperwork Matters More Than You Think
Ultimately, none of this documentation is optional busywork. It's proof. Consequently, without it, you have no real way to verify your new home received the protection you paid for. At EcoFusion Pest Control, we regularly get called in after closing, once a homeowner realizes they never received any of these documents. In many cases, we can still perform a professional termite inspection to check current conditions, but it's far easier to confirm everything upfront than to guess after the fact. Either way, don't let excitement over move-in day push this paperwork to the bottom of the pile.
So, before you close on your new home, gather every document above. Request the certificate, the diagram, the warranty terms, and inspection confirmation. If anything is missing, ask your builder directly — a reputable one will have no trouble producing it. And if you're buying an existing resale home instead of new construction, a real estate WDI inspection serves a similar purpose, confirming termite conditions before you sign anything. Either way, our team is glad to help you make sense of the paperwork, or the property itself.
