Drainage of rainwater off of a home site is important as excessive or inadequate moisture can greatly affect a home and its integrity. Home sites with slopes are easier to handle, however, care must be taken to not undermine the foundation. Flat sites are often the easiest and least expensive types to build a home on. However, they lead to poor drainage of rainwater leading to a risk of moisture penetration and rotting in the framing of the home. If the lot is flat, a professional home contractor will raise the area where the home will be built before construction begins. If a home is already built and is on a low-lying area, a professional home inspector can thoroughly inspect the home for damage caused by poor drainage issues and suggest repairs to make the home more functional.
Drainage can be improved by cutting in a “swale” which is a drainage channel to route water around the home or by installing surface water drains can control drainage.
