Most thin, vertical cracks in a poured concrete basement wall are shrinkage cracks and can be sealed for a few hundred dollars. But in north-central and eastern Connecticut, spiderweb-style cracking can be a sign of pyrrhotite, the mineral behind the state's crumbling foundation problem, and that can't be patched. The fix is to lift the house and replace the foundation, which can cost around $150,000, and the state-created CFSIC program may pay a large share.
What to look for
- Map-pattern or spiderweb cracking in basement walls
- Cracks with white or rust-orange staining, or concrete that flakes or crumbles
- Horizontal cracks or walls that bow inward
- Doors and windows that stick, or floors that slope
- Water seeping in through cracks
- A poured concrete foundation built from about 1983 on in the Stafford Springs area or nearby towns

- Under Public Act 16-45, town assessors must reassess homes with defective concrete foundations, and insurers can't cancel or refuse to renew a homeowners policy because of a crumbling foundation.

DIY or hire a pro?
Sealing a thin, dry, non-moving crack with an epoxy or polyurethane kit is a fair DIY job. Any map-pattern cracking, bowing walls, or cracks that keep growing need an engineer's evaluation, and foundation replacement needs a building permit and a registered contractor.
If fixing it is more than you want to take on
With an ordinary crack, a repair and engineer's letter usually lets you list normally. With a confirmed or suspected crumbling foundation, you can apply to CFSIC and replace it before selling, sell as-is on the open market with full disclosure (many buyers' lenders will balk), or sell as-is to a cash buyer. A cash sale is faster and avoids the replacement project, but the price will reflect the foundation, so it will be well below what a house with a new foundation would bring.
Want a cash offer on the house as it is?
Sell 2 Us buys houses as-is across Connecticut: no repairs, no cleanout, no fees. You pick the closing date.
Common questions
What is pyrrhotite?
Pyrrhotite is an iron sulfide mineral found in some aggregate used in concrete. When it's exposed to air and water it expands and cracks the concrete over time, which is what causes crumbling foundations in parts of Connecticut.
How do I know if my foundation has pyrrhotite?
Visible map-pattern cracking is a warning sign, but the reliable answer is a visual inspection plus a core test by a licensed professional engineer. Connecticut reimburses part of that testing for eligible homes.
How much does CFSIC pay for a crumbling foundation?
For proposals submitted on or after January 20, 2026, CFSIC caps payments at $205,000 per eligible home and $82,000 per eligible condo unit. You pay anything above the cap.
Are all foundation cracks a sign of a crumbling foundation?
No. Thin vertical shrinkage cracks are common in poured concrete and are often cosmetic. Spiderweb cracking, crumbling concrete, or cracks that keep widening are the ones to have an engineer look at.
Will a crumbling foundation lower my property taxes in Connecticut?
It can. State law requires assessors to reassess homes with defective concrete foundations, so contact your town assessor with your engineer's report.
Can I sell a house with a crumbling foundation in Connecticut?
Yes. You must answer the disclosure form's foundation and pyrrhotite questions honestly, and many buyers will need cash or a special loan, so expect a lower price or a longer sale.
