A termite inspection when buying a home is a visual check, by a trained inspector, for wood-destroying insects and their damage. In Tennessee the licence category is Wood Destroying Organisms (WDO). The report records what was found and what could not be seen. We do not state what any rule requires at sale; ask your agent and lender.
Key takeaways
- A wood-destroying insect inspection is a visual survey of the accessible parts of a house for termites, carpenter ants, wood-boring beetles and the damage they cause. It records what was seen and, just as important, what could not be reached.
- Wood Destroying Organisms (WDO) is one of the licence categories the Tennessee Department of Agriculture uses for commercial pest control, so a company doing this work should hold that category.
- We could not source what Tennessee or any local rule requires at sale, so this guide describes what to ask for and not what is mandatory. Your agent, lender and the sales contract are where requirements are set.
- Most Brentwood homes were built from the 1980s onward, so crawl spaces, slabs, additions and landscaping at the foundation are the usual places to look. Older houses in neighborhoods such as central Franklin and Nashville bring other questions.
- A clear report is a snapshot, not a guarantee. Ask what was inaccessible, what was recommended, and whether treatment history exists for the house.
What is a termite or WDI inspection when you buy a house?
It is a visual inspection of the accessible areas of a house for evidence of wood-destroying insects, mainly subterranean termites, and for conditions that favor them. The inspector looks for live insects, mud tubes, damaged wood and moisture, and writes up what was found, what was not reachable and what is recommended.
You will hear the same thing called a termite inspection, a wood-destroying insect (WDI) report, a wood-destroying organism (WDO) report, or a pest inspection. The terms overlap in daily use. WDO is the term the Tennessee Department of Agriculture uses for one of its pest control licence categories, Wood Destroying Organisms, which sits alongside General Pest and Rodent Control, Fumigation and Bird Control. That information comes from tn.gov summaries we saw, not from a full reading of the licensing rules.
The scope is deliberately narrow. This is not a general home inspection and it does not assess the roof, wiring or plumbing. It looks at wood in and around the structure and asks whether insects that eat wood are active, have been active, or are likely to become active because of how the house is built and kept.
In practice the inspector walks the exterior and the interior, enters the crawl space or looks at the slab edge, checks the attic where it is reachable, and probes or taps suspect wood. At the end there is a written report. For a buyer, the value is not a pass or fail but the detail: where the evidence was, how far it extends, and what the inspector could not see.
Our termite inspection page describes the visit in more detail, including what to prepare.
Does Tennessee require a termite inspection to sell or buy a house?
We could not source Tennessee's termite-disclosure or inspection rules, so we will not tell you what the law requires. Lenders, sales contracts and agents often ask for a wood-destroying insect report, but that is a matter for your contract and your lender. Ask your real estate agent and lender what applies to your purchase.
This is the point where many guides state a rule with confidence. We would rather not. We looked for a Tennessee requirement or a local one for Brentwood, Franklin or Nashville and did not find one we could verify, so nothing here should be read as legal advice or as a description of what any law demands.
What we can say is practical. A buyer can ask for a wood-destroying insect inspection as part of due diligence, and many do. The sales contract usually sets whether it is a condition of the purchase, who orders it, who pays and how long the buyer has to act on the result. A lender may also ask for a report as part of its own process. Those are details to check in your contract, not things this page can settle.
One useful habit is to ask early. Inspections take scheduling, and a buyer with a short option period does not want to wait for a slot. A real estate agent can tell you what is typical locally, and your attorney can tell you what your contract means.
If you want an inspection and are not sure where to begin, call (855) 974-4733, and the call line will connect you with an independent local licensed pest-control company.
What does the inspector look at in a Brentwood-area house?
The inspector checks the foundation edge, the crawl space or slab perimeter, sills, joists and subfloor where reachable, door and window frames, the garage, the attic where accessible, and wood that touches soil. They look for live insects, mud tubes, frass, damaged wood, moisture and conditions that attract termites.
Most Brentwood homes were built from the 1980s onward, and crawl spaces and slabs are both common in the area. That shapes the inspection. On a slab, the inspector focuses on the exterior perimeter, the garage, the edges of slab penetrations and any interior wood that sits near the floor. In a crawl space, the inspector goes under the house to look at piers, sill plates, joists, plumbing penetrations and the condition of the ground cover.
The table lists the common areas and what the inspector is looking for.
Landscaping matters as much as the building. Mulch piled against siding, soil above the slab edge, a deck post set in the ground, firewood stacked against a wall and downspouts that empty at the foundation all create conditions termites like. Wooded lots add stumps, root systems and fallen limbs that can host colonies close to a house.
| Area | What the inspector is looking for |
|---|---|
| Foundation exterior | Mud tubes, soil or mulch covering the slab edge, wood or trim touching soil, cracks and gaps. |
| Crawl space | Mud tubes on piers and walls, damaged or soft joists and sill plates, standing moisture, loose vapor barrier, debris wood. |
| Slab edge and garage | Evidence at expansion joints and penetrations, damaged wood along the garage floor edge, stored wood and cardboard. |
| Interior walls and floors | Hollow-sounding wood, blistered paint or drywall, shed wings on sills, frass from wood-boring insects. |
| Doors and windows | Damaged frames, water staining, previous repairs that hide damage. |
| Attic where accessible | Evidence of carpenter ants or other wood-feeding insects, roof leaks that dampen framing. |
| Decks, porches and outbuildings | Posts in contact with soil, rail and ledger connections, sheds and fences that touch the house. |
What is different in older houses and in additions?
Older houses and additions give termites more places to hide. Older wood framing, patched floors, finished basements or enclosed porches and later additions that join to the original structure can all hide damage and cut off access. The report should say clearly what was not reachable so you know what remains unchecked.
Brentwood is mostly newer housing, but the area around it is not. Central Franklin and the older parts of Nashville, Old Hickory, Murfreesboro and Ashland City have older wood-framed homes in what we would call older neighborhoods. We do not have a sourced date for any particular street, and we are not saying age alone makes a house a problem. We are saying that older houses have had more years for something to go wrong and more renovation layers over it.
Additions are the pattern to ask about everywhere, including newer neighborhoods. Where an addition meets the original house, the foundation type can change, from a crawl space to a slab for instance, and a concealed joint can sit between them. A bonus room over a garage, an enclosed porch and a sunroom are all places where wood and moisture can meet where nobody sees it.
Previous repairs are another question. Fresh paint, new trim or a replaced section of subfloor may be perfectly ordinary maintenance. They may also cover earlier damage. A good inspector will say what looks repaired and recommend a closer look if it is not clear what is behind it.
The practical advice is to ask the seller whether there was ever termite activity, treatment or repair in the house, and whether any paperwork exists. A previous treatment is information, not a reason to walk away, and the paperwork may show what was used and when.
How do you read the report?
Read it for three things: what was found, what could not be inspected, and what the inspector recommends. Evidence of live insects, old damage and conducive conditions are different findings. A report with large inaccessible areas is less reassuring than one that says everything was reachable. Ask the inspector to walk you through it.
Reports vary, but the structure is similar. There is usually a section identifying the property and the person who inspected it, a section on findings, a diagram or description of where evidence was seen, and a section on recommendations. The language is often technical, and the inspector can explain it.
Live activity, previous activity and conducive conditions are three separate things. Live activity means insects were found active. Previous activity means signs, such as old mud tubes or repaired damage, with no active insects found. Conducive conditions are things like wood in contact with soil or moisture problems that raise the chance of a future problem. Each leads to a different response, from treatment to repair to a landscaping change.
Do not skip the section on inaccessible areas. A crawl space full of stored items, a wall with no access panel or a finished attic limits what can be seen. If a large part of the house could not be checked, ask whether access can be arranged before closing. A report that says nothing was found in the areas that could be reached is true and limited at the same time.
Ask whether the report is a record of the day and nothing more. It is. Termites can arrive after a clear inspection, and an inspection cannot see inside sealed walls. Think of it as a good snapshot that helps you negotiate and plan.
What happens if the inspector finds termites?
Finding termites during a purchase is common enough to be a routine negotiation, not a reason to panic. The usual next steps are a closer look at the extent of damage, a treatment quote, and a conversation through your agent about repair and who pays. Treatment options depend on the house and the foundation type.
First, ask the inspector how far the activity extends and whether there is damage that needs a structural opinion. Treatment and repair are separate questions: treatment stops the insects, repair fixes the wood. A general contractor or a structural professional deals with damaged framing.
Second, get a treatment quote in writing, with the method and what it covers. Our termite treatment page describes the two broad approaches, a liquid barrier and a bait system, and why the choice depends on the foundation and access. The price is confirmed by the technician after seeing the house, which also applies if you are comparing figures; our guide to pest control cost in Brentwood explains why we print no local number.
Third, take the findings to your agent. Whether to ask the seller for treatment, a credit or a repair, or to walk away, depends on your contract and your tolerance. That is a decision for you and your advisers, and we do not suggest an outcome.
After the sale, ask for a record of whatever treatment is done and keep it with the house documents. A future buyer, and your own technician, will want to know what was applied and where.
How do you choose who does the inspection?
Choose a company with the Wood Destroying Organisms category under the Tennessee Department of Agriculture, and check it against the department's list of chartered companies before you hire. Ask who will inspect, what the report covers, and whether the person inspecting is separate from anyone selling treatment.
The Tennessee Department of Agriculture licenses commercial pest control, and a company offering custom pesticide application needs a pest control charter. The department suggests checking its list of chartered companies and says a charter number should be visible on the company's vehicle. Licences are category-specific, and WDO is the category for wood-destroying organisms. We took this from tn.gov summaries and do not print any number here. Our guide on how to check a Tennessee pest control company goes through it step by step.
A fair question for a buyer is whether the inspector has a stake in what happens next. An inspector who is also selling the treatment can be perfectly honest, and some buyers still prefer a report from someone who is not. Ask how the company handles that, and decide for yourself.
Finally, ask for the report to be sent to you directly and to include photographs where it can. A picture of mud tubes on a pier is worth more than a line in a checklist.
Frequently asked questions
What is the difference between a termite inspection and a WDI or WDO report?
In daily use they mean much the same thing. WDI and WDO reports cover wood-destroying insects and organisms more broadly than termites alone, including carpenter ants and wood-boring beetles. Ask the company what its report covers.
Does Tennessee require a termite inspection when you buy a house?
We could not source a Tennessee or local requirement, so we do not say what the law demands. Your sales contract, lender and agent decide whether a wood-destroying insect report is part of your purchase.
How long does a termite inspection take?
It depends on the size of the house and whether there is a crawl space. A visit often takes a good part of an hour or more, and a difficult crawl space adds time. Ask when scheduling.
Is a clear termite report a guarantee?
No. It records what the inspector could see on the day. Termites can arrive later, and areas that cannot be reached are not covered. Read the inaccessible-areas section carefully.
Should I inspect a newer Brentwood house too?
Many buyers do, since age is not the only factor. Crawl spaces, landscaping at the foundation, additions and wooded lots all matter regardless of when the house was built.
