If you’re a homeowner in Massachusetts or Connecticut, foundation damage due to pyrrhotite is a serious concern. This iron sulfide mineral, when present in concrete, reacts with oxygen and water, causing progressive cracking and crumbling over time. Unfortunately, pyrrhotite-related deterioration isn’t just a cosmetic issue—it can compromise the structural integrity of your home.
At MKC Home Inspection, we specialize in helping homeowners identify potential foundation issues before they become costly disasters. Below, we outline the warning signs of pyrrhotite damage and what you can do to protect your home.
Pyrrhotite-related foundation issues develop gradually, but early detection is key. Here are some telltale signs homeowners should look for:
One of the most recognizable symptoms of pyrrhotite deterioration is "map cracking"—a spiderweb-like network of cracks on your foundation walls or floors. These cracks may start small but will continue to expand over time.
While small foundation cracks are common in any home, deep, widening horizontal or vertical cracks are a red flag. Pyrrhotite causes the concrete to expand and break apart, often resulting in large, spreading cracks that don’t follow the typical settling pattern of a home.
If your foundation walls appear to be bulging outward or bowing inward, this could be a sign of internal pressure from pyrrhotite-related expansion. This type of movement can lead to structural failure if left unaddressed.
As the foundation weakens, it may no longer be able to properly support the floors above. If you notice floors becoming uneven, sloped, or sagging, pyrrhotite may be compromising your home’s structural stability.
A shifting foundation can cause door frames and window frames to become misaligned, making them difficult to open and close. If you’re experiencing these issues along with foundation cracks, it’s worth investigating further.
Pyrrhotite deterioration often results in chipping, flaking, or crumbling concrete that is noticeably weaker than surrounding areas. If you can break off small pieces of concrete with minimal effort, it may be deteriorating from the inside out.
If you suspect pyrrhotite in your foundation, don’t panic—but act fast. Addressing the issue early can save you thousands in repair costs.
At MKC Home Inspection, we provide comprehensive foundation assessments to determine whether your home shows signs of pyrrhotite damage. Our trained inspectors can identify early warning signs that may not be obvious to the untrained eye.
The only way to officially confirm the presence of pyrrhotite is through core sampling, where core samples from the foundation concrete are tested in a lab. We can guide homeowners through the process of arranging a core test if necessary.
Connecticut currently offers financial relief programs for affected homeowners, and Massachusetts is working on similar initiatives. MKC Home Inspection stays up-to-date on local assistance programs and can help point you in the right direction.

Pyrrhotite is an iron sulfide mineral that, when exposed to oxygen and water, causes concrete to deteriorate. This leads to cracking, crumbling, and structural instability in foundations.
Look for spiderweb (map) cracking, horizontal and vertical cracks, bulging walls, uneven floors, sticking doors/windows, and crumbling concrete. A professional inspection can help confirm warning signs.
Pyrrhotite contamination is most commonly found in northern Connecticut and central/western Massachusetts due to certain rock formations used in concrete production.
Yes! MKC Home Inspection can assess visible signs of pyrrhotite-related damage and recommend further testing if needed.
The most accurate method is a core sample test, where a concrete sample is analyzed in a lab for pyrrhotite content.
Consult with a structural engineer to assess the damage. You may also qualify for financial assistance programs in Connecticut and Massachusetts.
Most insurance policies do not cover foundation damage from pyrrhotite. However, some state relief programs may help with repair costs.
Severe cases often require full foundation replacement, which can be costly. Some homeowners explore reinforcement methods, but these may only delay the inevitable.
Yes! Connecticut has funding programs, and Massachusetts is working on similar support initiatives. MKC Home Inspection stays updated on available resources.
