Scranton grew up on anthracite coal, and the ground beneath much of the city and the surrounding valley was mined heavily for the better part of a century. That history leads to a question we hear a lot: could my foundation problem be mine subsidence? It's a fair thing to ask around here, so here's a straight explanation of what it is, how it differs from ordinary settlement, and what your options are.
What mine subsidence actually is
Mine subsidence is the movement of the ground surface caused by the collapse or shifting of old underground mine workings below. When mines close, voids and supporting pillars left behind can, over long periods, give way. The ground above then sinks or shifts. It's different from settlement, which is about the soil directly under your footing compressing or washing away.
How it's different from regular settlement
Ordinary settlement and mine subsidence can look similar from inside a house — cracks, sloping floors, sticking doors. The differences are usually in the pattern and scale. Everyday settlement tends to be localized to one corner or section and traces back to soil or water near the foundation. Ground movement from mining can affect a broader area and isn't tied to the drainage or soil conditions right around your house. Neither is something to diagnose from a distance, which is the whole point of an inspection.
Why this matters for how you handle it
The distinction isn't academic. Standard foundation repairs — piers, anchors, crack sealing — address the structure and the soil right around it. If the underlying cause is mining-related ground movement over a wider area, that's a different situation, and it's one where Pennsylvania has a specific program that comes into play.
Pennsylvania's mine subsidence insurance
Pennsylvania runs a state Mine Subsidence Insurance program specifically because standard homeowners policies generally don't cover damage from mine subsidence. It's administered through the state's Department of Environmental Protection and is available to property owners in the historic coal regions, which includes the anthracite areas around Scranton. Coverage and eligibility have their own rules, so if mine subsidence is a genuine concern for your property, the program's own office is the authoritative place to check details and get accurate, current information.
What to do if you're worried about it
Start with an inspection of what's actually happening at your house. A careful look at the cracks, the floors, and the way any movement is distributed will usually indicate whether you're dealing with something local and fixable or something that warrants looking into the mine subsidence angle. From there, you can make an informed decision — including looking into the state's insurance program if it's warranted.
We're glad to set up that first look for free and connect you with a licensed local contractor who gives you an honest read. The contractor is a foundation repair company, not the state program, so if your situation points toward mine subsidence you'll be told and sent to the right place rather than sold a repair that doesn't address the cause.
Worried it might be more than settlement?
We'll connect you with a local contractor who inspects what's happening at your house and tells you honestly whether it looks local and fixable or worth checking the mine subsidence angle.
