Caulking in Bonita, CA.
Caulking for Bonita 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 South County San Diego?
High-density housing in National City and Chula Vista sees heavy plumbing use, and grout and caulk at tub surrounds fail faster in units with multiple occupants. A failed tub caulk line lets water migrate under the tub and into the subfloor — we check for soft spots in the floor before sealing because a compromised subfloor changes the scope of the repair.

- Shower and tub perimeter re-caulking — complete removal and replacement with mold-resistant silicone

- Exterior door and window surround caulking with paintable sealant
