Waterproofing problems we can help with in San Francisco
Why San Francisco homes take on water
Basements are common here, and every basement is surrounded by soil that holds water. When that soil is saturated, water finds the weakest points—cracks, the wall-floor joint, window wells and pipe penetrations.
Older foundations—stone, brick and early concrete block—were rarely built with modern drainage or waterproofing, which is why so many older basements leak.

San Francisco waterproofing questions
Can I get emergency help with a wet basement in San Francisco tonight?
Call and we'll try to connect you with an available waterproofing contractor who serves San Francisco. Availability depends on the time and how widespread the weather event is—after a major storm, demand is high. Ask for an arrival time when you're connected.
Is water in my basement covered by insurance?
It depends on the source and your policy. Sudden pipe bursts are often covered; groundwater seepage and surface flooding usually aren't without separate flood coverage. Photograph the damage and call your insurer.
What's the difference between water removal and waterproofing?
Water removal gets the water out now. Waterproofing stops it from coming back—drainage, sump systems, crack repair or exterior work. Many contractors do both.
Is your service free?
