Manage Water Before It Reaches the House
Drainage deals with liquid water. Start with where rain and groundwater collect, then determine whether a foundation drain and sump system are needed.
Check roof runoff and surface drainage
Look for overflowing gutters, disconnected downspouts and ground that channels water toward the foundation. Trace runoff during or after rain from a safe location. Water should discharge to a suitable location rather than collect beside the house.
Site grading and drainage work must account for utilities, neighboring property and local discharge rules. Get a site-specific plan before excavation.
Understand the sump pump’s job
A sump pump removes water collected in a basin, often from a foundation drainage system. It does not lower air humidity in place of a dehumidifier. The pump, basin and discharge route need to suit the expected water load and lift.
Ask an installer about float clearance, a suitable basin cover, discharge routing and backflow prevention. Confirm how the system will be checked and maintained.
Plan for failures and power outages
Discuss an appropriate backup and high-water alarm when pump failure could cause damage. Battery and water-powered backup systems have different supply and installation requirements; check the specific equipment and local rules with the installer.
Your next step
Sketch where water appears, where the pump discharges and what happens during heavy rain. Share those observations when arranging a drainage assessment.
