If you're a homeowner in north-central Connecticut or south-central Massachusetts, there’s a growing issue you need to know about: Pyrrhotite in concrete foundations. This naturally occurring mineral, while seemingly harmless in its raw state, can wreak havoc when it finds its way into concrete. It’s a problem with devastating consequences, and understanding it is critical.
Pyrrhotite is a mineral that contains iron sulfide. When exposed to water and oxygen, it reacts chemically, causing the concrete to expand and crack. Over time, this process can lead to complete foundation failure. Homeowners affected by Pyrrhotite often face crumbling foundations, with repair costs exceeding $100,000—a financial burden that homeowner’s insurance typically does not cover.
The issue traces back to at least one quarry in Connecticut, where concrete containing Pyrrhotite was produced from 1983 to 2015. Many homes built or renovated during this period in north-central Connecticut and south-central Massachusetts are at risk. However, the problem is not confined to these areas; reports of affected homes are emerging from surrounding regions, indicating the issue is spreading.
The damage from Pyrrhotite isn’t immediate. It can take anywhere from a few years after the concrete is poured to as long as 30 years for visible signs of deterioration to appear. By the time the cracks and crumbling are noticeable, the damage is often irreversible, requiring a complete foundation replacement.
In Connecticut, a relief program has been established to assist affected homeowners. This program provides financial aid for foundation replacement, offering some relief from the enormous costs.
Massachusetts, however, lags behind. The state currently only offers partial reimbursement for core sample testing to determine if Pyrrhotite is present in the foundation. While this is a start, it leaves many homeowners grappling with overwhelming repair expenses without sufficient support.

If you live in an area affected by Pyrrhotite, here are steps you can take:
Pyrrhotite in foundations is not just a homeowner issue—it’s a community issue. It affects property values, local economies, and the financial security of families. As more homes are tested and cases come to light, this topic will likely dominate real estate and construction conversations in the region.
For further information on the broader implications of Pyrrhotite, check out these resources:
1. Legislative Efforts in Massachusetts
In December 2024, despite the Massachusetts State Senate approving legislation to assist homeowners with crumbling foundations, the House of Representatives did not act on the bill. This inaction means the legislation will need to be refiled in the upcoming session. The proposed bill aimed to provide relief to homeowners facing significant repair costs due to pyrrhotite contamination. Lawmakers have expressed disappointment and emphasized the urgency of addressing this issue. Yahoo
2. Expansion of Affected Areas
Recent reports indicate that the problem of pyrrhotite-contaminated concrete is more widespread than previously thought. A significant case emerged in Dracut, Massachusetts, where a large condominium complex discovered pyrrhotite in its foundations. This finding suggests that the issue extends beyond the initially identified regions, potentially affecting numerous properties across the state. WCVB
3. Scientific Research and Mapping
The U.S. Geological Survey (USGS) has released a map highlighting areas in the contiguous United States where pyrrhotite may occur. This resource aims to help identify regions at risk and prevent the use of pyrrhotite-containing aggregate in future construction projects. USGS
4. Homeowner Advocacy and Support
Organizations such as the Massachusetts Residents Against Crumbling Foundations are actively advocating for affected homeowners. They are pushing for legislative action and increased awareness to secure financial assistance and support for those dealing with pyrrhotite-related foundation issues. Boston
