Selling a House With a Crumbling Foundation in Connecticut
Map cracking, pyrrhotite test results, a claim that stalled. Here is how a pyrrhotite house can still be sold, and what a CT MAX cash offer looks like when the concrete is the problem.

What a crumbling foundation means here
Thousands of Connecticut houses, mostly in the north-central and northeastern part of the state, were built with concrete containing pyrrhotite, an iron sulfide mineral. Over time it reacts with water and oxygen, the concrete swells, and walls develop spiderweb or “map” cracking. The damage keeps progressing. The accepted fix is to lift the house and replace the foundation.
Why a regular sale gets hard
- Disclosure. Connecticut’s residential property condition disclosure asks sellers about foundation testing and known concrete problems. What you know, you share.
- Financing. Many lenders will not finance a house with a confirmed or suspected failing foundation, which removes most buyers.
- Inspection. Even without a test, visible map cracking usually ends a deal after the inspection.
Your options
- Test first. A core sample tells you whether pyrrhotite is present and how much.
- Apply for state-backed help. The Connecticut Foundation Solutions Indemnity Company (CFSIC) offers financial help to eligible owners for foundation replacement. Check its current rules and waitlist.
- Replace, then list. Brings full value but takes months and large upfront costs.
- Sell as it stands. The price reflects the foundation, but you are done with the problem.
How CT MAX handles a pyrrhotite house
We look at the house, the test results if you have them, and the neighborhood. Your MAX Offer is written with the foundation already priced in, so no inspection surprise can change it later. We do not need bank approval, and the closing attorney handles the paperwork on the date you pick.
Common questions
Do I have to test before I sell to CT MAX?
No. If you have results, share them. If you do not, we price the house on what we see and what is known about the area.
Can I sell while my CFSIC application is pending?
Talk to CFSIC and your attorney first, because selling can affect eligibility. We will work around whatever you decide.
Is every cracked foundation pyrrhotite?
No. Shrinkage cracks are common in any poured wall. Map-pattern cracking that widens over time is the warning sign.
