Caulking in Coronado, CA.
Caulking for Coronado 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 Coastal San Diego?
The gap between indoor humidity and the dry-then-damp coastal air cycle causes caulk at window frames, shower enclosures, and exterior penetrations to harden, crack, and pull away within two to three years in La Jolla and Del Mar. We use silicone-modified latex caulk for interior applications and pure silicone on all exterior surfaces facing the ocean — polyurethane sealants in this environment UV-degrade too fast.
