Most of the houses we see in Greater Hartford and eastern Connecticut are wood-framed and old: capes and colonials in the suburbs, and two- and three-family houses in New Britain, Hartford and Norwich that went up before the Second World War. Wood that has sat on a stone or block foundation for eighty years, close to damp soil, is exactly what Connecticut's termites look for. So when a seller finds mud tubes on the basement wall or a soft spot in a sill plate, the first question is rarely "is this bad?" It is "can I still sell this house, and what do I have to tell a buyer?" This guide answers both.
Yes, you can sell a Connecticut house with termite or carpenter ant damage. The state's Residential Property Condition Report asks directly about "termite, insect, rodent or pest infestation problems" and about "rot or water damage problems," so anything you actually know about goes on the form. Most buyers' lenders and inspectors will look for wood-destroying insects anyway. Your realistic choices are to treat and repair first and then list, to treat, disclose and give the buyer a credit, or to sell as-is to a buyer who prices the damage in. The damage usually moves slowly, so you have time to get proper quotes before you decide.
First: termites or carpenter ants?
It matters which insect you have, because the two point to different problems. According to the Connecticut Agricultural Experiment Station (CAES), the species most often found in New England is the eastern subterranean termite, which lives in the soil and tunnels up into wood that touches or sits close to the ground. Carpenter ants are the other common culprit, and CAES notes they only excavate wood that has already been damaged by water. Termites can eat sound wood.
| Sign | Termites | Carpenter ants |
|---|---|---|
| What you find | Pencil-width mud "shelter tubes" on foundation walls or piers | Small piles of coarse sawdust mixed with debris |
| Damaged wood | Looks intact outside, sounds hollow when tapped; galleries lined with mud | Clean, smooth galleries limited to the water-damaged area |
| Swarms | Spring only, usually March to June (occasionally a warm winter day) | Late spring into fall |
| Winged insects | Straight, beaded antennae; thick waist; wings of equal length | Elbowed antennae; narrow waist; front wings longer |
| What it tells you | Soil contact or moisture at the foundation | A leak or water problem somewhere in the house |
Carpenter ants are often the messenger for a bigger issue. If they are in a bathroom wall or under a porch roof, the real cost may be the leak that softened the wood in the first place. Termite damage tends to show up low in the house: sill plates, the ends of floor joists, basement stair stringers, door frames and porch posts. If your basement also has cracking walls, read our guide to selling a house with a crumbling foundation in Connecticut before you assume the insects are the whole story.
What the buyer's inspection will find
Even if you have never seen a termite, assume the buyer's side will look. Most Connecticut buyers hire a home inspector, and many add a wood-destroying insect (WDI) inspection. The industry's standard report, the NPMA-33 form, treats termites, carpenter ants, carpenter bees and wood-boring beetles as wood-destroying insects, and it is written to note visible evidence, not to guarantee what is hidden behind finished walls.
Financing adds another layer. Government-backed loans can require a clean WDI report before closing, for example when the appraiser notes signs of infestation, and lenders treat those reports as good for a limited time (the NPMA-33 form itself says 90 days for mortgage purposes). On an older house that already has other issues, this is often where a deal starts to wobble. We wrote up one Norwich two-family where three financed buyers in a row fell through over appraisal conditions and old-house problems, and our page on what to do when a home sale falls through covers that situation in general.
CAES advises against do-it-yourself termite treatment, noting it is expensive and ineffective and that homeowner-applied treatments will not satisfy a home inspection when the house is later sold. If you treat before selling, use a licensed pest management professional and keep the paperwork.
Your disclosure duty in Connecticut
Connecticut's Uniform Property Condition Disclosure Act (Conn. Gen. Stat. §20-327b) requires most sellers of one- to four-unit homes, condos and co-ops to give the buyer the Department of Consumer Protection's Residential Property Condition Report before the buyer signs a binder or contract. The current form (revised July 2025) asks:
- Question 54: "Termite, insect, rodent or pest infestation problems? If yes, explain."
- Question 55: "Rot or water damage problems? If yes, explain."
What the law asks of you, and what it does not:
- It is about what you actually know. Under §20-327e your answers extend only to your actual knowledge, and under §20-327d you are not required to order inspections or tests to fill in the form. "Unknown" is an honest answer when it is true.
- It is not a warranty. The form itself says the seller's statements are not a warranty and are not a substitute for the buyer's own inspections.
- Skipping the form costs $500, and does not end the matter. Section 20-327c requires the contract to give the buyer a $500 credit at closing if the seller doesn't furnish the report. The same section says that credit does not excuse you from disclosing a defect you know about that significantly impairs the home's value, the health or safety of its occupants, or its useful life, and a buyer can sue for actual damages if you don't.
- Some sellers are exempt from the form. Section 20-327b(b) exempts transfers by executors, administrators, trustees and conservators, and transfers of property taken by foreclosure, among others. If you are selling as an estate fiduciary, see our Connecticut inherited-house and probate guide or our guide to selling under a conservatorship, and ask your attorney what to disclose anyway.
A past infestation that was treated is still worth explaining on the form. Attach the treatment report, any service agreement and repair invoices. A buyer reading "treated in 2019 by a licensed company, sills replaced, annual monitoring since" is far calmer than one whose inspector finds old mud tubes nobody mentioned.
Painting over damage, patching mud tubes or hiding a soft sill before showings turns a repair problem into a legal one. Disclose what you know and let the price reflect it.
Will homeowners insurance pay for it?
Usually not. Standard homeowners policies generally exclude damage caused by insects, and termite damage that builds up slowly over years is the textbook example. There can be exceptions where insect activity leads to a separate covered loss, so read your own policy or call your agent, but plan as if the treatment and the carpentry come out of your pocket or out of the sale price.
Should you treat and repair before you sell?
Treatment, at least, usually makes sense if you plan to list, because an untreated active infestation is the thing most likely to scare a financed buyer or stall an appraisal. CAES makes two points worth keeping in mind:
- There is time to shop around. Termite damage progresses slowly. CAES puts a colony's average excavation at about one square foot of wood a year and says hasty action isn't required.
- Get more than one opinion. CAES suggests interviewing several pest management professionals, discarding extremely high and low quotes, and agreeing on a clear plan (soil treatment, baits or barriers) before work starts.
Structural repair is a separate decision. Replacing a section of sill plate or sistering a few joist ends is ordinary carpentry. Replacing long runs of sill on an occupied two-family, or rebuilding a porch, is a real project, and structural work may need a permit from your town's building department. Get the carpentry quote before you decide, not after. Our comparison of selling as-is versus renovating first walks through which repairs tend to pay for themselves in this market.
Your three real options
1. Treat, repair, then list
If the damage is limited and the rest of the house shows well, this usually brings the highest price. Keep every invoice and the treatment warranty, disclose the history on the condition report, and expect the buyer's inspector to look closely at the repaired areas.
2. Treat, disclose and offer a credit
Some sellers stop the infestation, leave the carpentry for the buyer and negotiate a price reduction or closing credit instead. This works best when the repair quote is in hand, so the number is grounded in something other than a nervous buyer's guess.
3. Sell as-is to a cash buyer
If the damage is extensive, the house has other problems stacked on top (old wiring, a wet basement, a tired roof), or you simply don't want to manage contractors, a direct sale as-is removes the inspection and appraisal hurdles. You will usually net less than a fully repaired listing. In exchange you get a fixed closing date, no repairs and no lender conditions. If wiring is part of the picture too, our guide to selling with knob-and-tube wiring covers that side.
How we help sellers with termite or ant damage
We buy houses with insect damage, rot and the leaks behind it across Greater Hartford and eastern Connecticut, from Hartford, New Britain and Manchester to Norwich and the New London County towns around our Taftville office. You don't need to treat first, open up walls or get repair bids for us. Tell us what you know, we walk the house, and we give you a written cash number with the damage already priced in. You still complete the condition report if the law requires it, and we will read it with you.
We will also tell you when a cash sale is the wrong answer. If the damage is a few feet of sill in an otherwise solid house, treating, repairing and listing will probably leave you with more. For the details, see how a cash sale works and the questions sellers ask most on our FAQ page.
Found termite damage in your house?
Tell us the town and what you've found, and we'll give you a fair, written cash number, a straight answer on whether repairing and listing would net you more, and a closing date that suits you. Zero obligation, and no pressure.
