Increase grade around your property: The dirt around the home should be sloped away from the house to divert water away. Very simply, have dirt three feet away from the structure, and toss it against the side of the house thus creating a slope.
Rain Gutters: A clogged rain gutter can send water cascading down the exterior wall, which can result in water entering the interior walls.
Rerouting down spouts: In a quick run to the local hardware store, homeowners can find a black, plastic corrugated 6-inch hose that fits around the base of the downspout. This device carries water away from the house, preventing it from seeping down into the foundation.
Maintain you roof: Where rain is concerned, the roof is the first line of defense. One small tear in a rubber membrane or crack in a tin roof, or compromise in the plywood structure of the roof can prove disastrous for the entire interior of the home. Have a roofer check out your home every five years.
Repair damaged windows: Proper window installation and maintenance is imperative. Modern windows are fitted with wells and drains designed to help direct water outside the house. Improper caulking can prove disastrous by sending water into the house that should be draining away from the window.
Clean debris: during spring and fall seasons, when leaves start to fall, it is critical to diligently sweep outdoor surfaces weekly, especially patios and door wells to prevent the collection of debris clogging exterior drains.
