What It Means for Your Home

• What works in your favorCecil drains well, so the soil beside a foundation usually dries out after a storm. It also changes size very little as it wets and dries, so the ground under the footings stays steady from season to season.
• FoundationsWater that collects against a foundation can keep the clay there soft, and soft clay can let a footing settle. Look for cracks in drywall, and cracks that step up through brick or block. See foundation repair.
• Crawl spacesEven soil that drains well can stay wet where roof runoff collects, and the ground still adds moisture to the air under a house, which can lead to musty odors, mold and wood rot over time. Look for sagging floors and deteriorating insulation. See crawl space repair and crawl space encapsulation.
• Floor framingDamp air under a house can rot and weaken joists and beams over time, which can show up as sagging or bouncy floors. Look for rotted floor joists, and broken or cracked joists. See framing repair.
• ConcreteSoftened clay where runoff collects can let part of a slab sink. Look for a cracked driveway and raised slab edges you can trip on. See concrete leveling.
