Crawl Space & Foundation Repair in Chapel Hill, NC

Chapel Hill Homes and What Is Under Them

Chapel Hill's established neighborhoods were largely built from the mid-twentieth century on, many of them on hilly, heavily wooded lots. A house built into a slope often has a crawl space that is deep on the downhill side and shallow on the uphill side, with the uphill foundation wall holding back soil — and every rainstorm running down toward it.

Heavy tree cover adds to it. Shade keeps the ground and the crawl space cooler and damper than an open lot would be, gutters fill with leaves and overflow beside the foundation, and roots can crowd old drain lines. None of this is unusual; it just means drainage and moisture control come up here more than anywhere else we work.

Common Problems We See in Chapel Hill

• Water entering the crawl space on the uphill side after heavy rain
• Damp soil and persistent high humidity in shaded crawl spaces
• Mold on joists and subfloor where moisture has stayed high for years — see mold removal
• Overflowing gutters and short downspouts discharging against the foundation
• Rot at sills and band joists on the wettest side of the house

The order of work matters. Sealing or encapsulating a crawl space that still takes on water after every storm traps the problem rather than fixing it, so on a sloped Chapel Hill lot the first step is usually getting water to go around the house — a French drain on the uphill side, a sump pump where water collects, or corrected grading — before the crawl space itself is sealed.
