How to Keep Water Out of a Garage

Install gutters, complete with downspouts and water drains, like a French drain, onto your property. Gutters collect and divert rainwater away from your garage. According to the Washington State University Clark County Extension, French drains are used to collect runoff from a gutter system and divert the water around buildings, like garages. You can purchase gutters, downspouts and drain kits from hardware stores.

Clean your gutters of leaves and debris regularly. Leaves, sticks and other debris have a tendency to clog up gutters, which allows excess water to spill out of the gutter and into your garage. Use a secure ladder to reach and clean the gutters and place all debris in a garbage can.

Install a garage door threshold. Garage door thresholds help prevent water and debris from entering your garage. You can purchase garage door thresholds from hardware stores.

Seal up any holes or openings in your garage with caulk to prevent rainwater from entering your garage. You can purchase caulking at hardware stores.
