Keep Water Where It Should Be — Away From Your Home
Water where it doesn’t belong leads to big problems: soggy yards, basement seepage, shifting foundations. At Harris Excavation, we install and maintain residential drainage systems anywhere from San Mateo to Mammoth Lakes that protect your home, property, and peace of mind — especially in California’s variable weather conditions.
From French drains and catch basins to grading adjustments and dry wells, we help homeowners manage stormwater effectively to get it away from their structures into the right spot. Whether you’re dealing with standing water after heavy rain or preparing a new build site for proper runoff, we bring precision, experience, and clear communication every step of the way
