Selling a House With a Crumbling Foundation in Connecticut

Quick answer: Yes, you can sell a Connecticut house that has a crumbling foundation, or one that might. What you cannot do is stay silent about what you know. Sellers must disclose it on the state's condition report, and in affected towns they also complete a second form just for the foundation. The price depends on what is documented, which is why an inspection report matters.

What is actually going on

Some concrete foundations poured in parts of Connecticut over the past several decades contain pyrrhotite, an iron sulfide mineral in the stone used to make the concrete. Over time it reacts and the foundation cracks and crumbles. The damage can take many years to show, and it cannot be reversed. The usual fix is replacing the foundation, which is typically a six-figure project.

The problem is concentrated in north-central and eastern Connecticut. The state's captive insurer for the issue, the Connecticut Foundation Solutions Indemnity Company (CFSIC), says about 41 towns may be affected.

What sellers must disclose

The Residential Property Condition Report. The standard seller form asks whether you have any knowledge of pyrrhotite in a foundation, and about foundation testing, inspections, damage and repairs. See the Connecticut property condition report for the full rules and the $500 credit.

The Residential Foundation Condition Report. A second, narrower form is required when you sell residential property in a town the Capitol Region Council of Governments has identified as affected or potentially affected. That list is on CRCOG's website. If you do not furnish the report, the buyer gets a $500 credit at closing.

Your answers are limited to your actual knowledge, and the forms are not a warranty. Answer honestly and do not guess. If you do not know, say so.

Why the inspection report matters

A foundation inspection by a Connecticut-licensed professional engineer or a CFSIC-certified home inspector assigns a severity class from 1 to 3. This is a different document from a general home inspection. CFSIC's guidelines tie a future claim to documentation completed before the sale, so a report can protect value for the next owner and give buyers something concrete to price.

The program is changing. CFSIC's board voted this summer to begin winding down its reimbursement (Type 2) claim category, and its funding depends on the state. Check crumblingfoundations.org for the current status before making a decision based on it.

Three ways to sell

1. Sell as-is with documentation. Get the foundation inspected, disclose everything, and price the home for what the report shows. This is the fastest route and is often the right one if the foundation is not yet failing. Our guide to selling a house as-is in Connecticut covers how to compare offers.

2. Inspect first, then decide. If you are not sure what you have, an inspection tells you before you list. A clean report helps your price. A bad one lets you price accurately instead of getting surprised in the middle of a contract.

3. Replace the foundation, then sell. This is the longest and most expensive path, and it depends on funding and contractor availability. It can make sense if you plan to stay while the work is done, and less so if you want to sell soon.

What to avoid

• Skipping the foundation form in an affected town

• Answering "no" when you simply have not looked

• Pricing as though the problem does not exist and hoping the inspection misses it

• Making decisions based on a program's status without checking its current rules

Buyers, lenders and appraisers are well aware of this issue in affected areas. A documented, honestly priced house is easier to sell than a mystery.

Questions sellers ask

Do I have to disclose pyrrhotite if I am not sure?

You must answer the forms honestly based on what you actually know. If you have no knowledge, say that. If you have any suspicion, an inspection removes the guesswork.

Is my town affected?

Check CRCOG's list of affected or potentially affected towns. It determines whether the foundation form is required.

Will it hurt my sale price?

A confirmed failing foundation reduces value substantially. A house with a clean inspection and documentation is in a much stronger position than an unknown.
