Why San Jose homes take on water
Most homes here are built on concrete slabs. Slab homes don't flood the way basements do, but poor drainage, cracked slabs and water pooling at the foundation can still let water in and damage floors and walls.
Homes here range from older block foundations with no exterior waterproofing to newer construction with basic damp-proofing that can fail over time.

San Jose waterproofing questions
Can I get emergency help with a wet basement in San Jose tonight?
Call and we'll try to connect you with an available waterproofing contractor who serves San Jose. 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?
Yes. Calling Waterproofing HQ is free. We're a referral service, not a contractor; you pay the independent contractor directly for work you approve.
