Now for the grading and drainage defects that come up during some home inspections in Houston. Poor drainage can cause many problems in a home starting with the foundation. If there is not a positive slope away from your foundation this can cause damage to your foundation, you could end up with water inside your home causing mildew, mold, and moisture damage. Gutters and downspouts play a big role in moving water away from your roof, foundation. Clogged improperly installed gutters are observed at many home inspections I have performed and can cause serious damage. Missing or damaged downspouts, and missing splash blocks or extenders can also contribute to issues. Extensive vegetation at the exterior veneers of the home can cause moisture issues.High soil around the foundation can be conducive to termite activity you will never see the termite tube in high soil areas. These are some common issues observed during a home inspection and will need some attention. Some of these issues are easy fixed just require a little maintenance. Poor drainage can be more complicated and more expensive may require drains, or moving soil.
