Keeping water away from your home’s foundation is an important part of maintaining your home's structural integrity. Water can cause soils to expand and contract as well as do damage to the interior of the home should it flood.
Keep your gutters clean and make sure downspouts will divert water to a place where it can drain away. If your home is equipped with a sump pit you may want to install a pump, or if you have a pump make sure it is operating properly. If your basement has a drain be sure it is clear in the event that you have an interior water leak, such as a broken pipe.
