Not sure which one you need?
Tell us what you are seeing and we will tell you what it is
Musty smell upstairs, cupping hardwood, a sagging spot in the floor, water on the basement floor after a storm, white powder on the block, insulation hanging down in the crawl space. Each one points to a cause, and the cause is what we fix.
- Musty smell or high humidity in the house: usually a crawl space moisture problem
- Bouncy or sagging floors: often joists or beams weakened by moisture
- Water on the basement floor after rain: drainage and hydrostatic pressure
- Black or white growth on wood or block: mold, and the moisture feeding it
