Caulking in San Diego, CA.
Caulking for San Diego homes, done by one handyman start to finish. Failed caulk is the most common path for water into walls, floors, and window frames — and it's cheap to fix before damage sets in. We remove old caulk completely, prep the joint, and apply the right product for the location: silicone for wet areas, paintable latex for trim and windows, polyurethane for exterior joints that see movement.
Why is caulking different in Central San Diego?
Older homes in North Park and South Park have caulk that was last applied in the 1990s and is now completely rigid — it no longer flexes with the structure, so every temperature swing opens new gaps. Recaulking an older home in this zone typically involves scraping out 25 to 30 linear feet of failed sealant before any new product goes in.
