Why Older Homes in Lancaster County Are More Prone to Foundation Issues
Like any structure, a home’s foundation naturally weakens with time. But older homes, especially those built before modern construction standards, are even more susceptible to foundation damage due to factors like:

- Aging Materials: Many historic homes in Lancaster County were built with fieldstone or early concrete mixtures that lack the durability of modern construction materials, making them more vulnerable to moisture damage and deterioration.
- Soil Movement: Pennsylvania’s mix of clay and silt soil expands and contracts with seasonal moisture changes, which can cause foundations to settle unevenly.
- Drainage Problems: Many older homes in the county weren’t built with modern drainage systems, leading to water pooling around foundations and accelerating damage.
- Extreme Weather: Freeze-thaw cycles common in Lancaster County can cause foundation materials to crack over time, especially in homes without updated waterproofing.

DIY Foundation Checks for Lancaster Homeowners
Before calling a professional, homeowners can conduct simple checks to assess potential foundation damage:

- Look for Exterior Cracks: Walk around your home and inspect the foundation for cracks. Small hairline cracks may be normal, but larger or widening cracks could indicate a serious issue.
- Test Doors and Windows: If multiple doors or windows suddenly become difficult to close, it could be due to foundation shifting.
- Inspect the Floors: Walk across rooms and feel for dips or slopes. Placing a marble on the floor can help you see if it rolls in one direction on its own.
- Check for Water in the Basement: Musty smells, damp walls, or puddles can indicate foundation cracks allowing moisture inside.
