Caulking in San Ysidro, CA.
Caulking for San Ysidro 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.

Why does caulk fail so fast in bathrooms?
Two main reasons: the original caulk wasn't cleaned or primed correctly, or the wrong product was used (latex caulk in a wet environment deteriorates quickly). Mold-resistant 100% silicone, applied over a spotlessly clean and dry joint, is what holds. We take the prep seriously.
Can you caulk over existing caulk?
No, not if you want it to last. Caulk over caulk peels within months because it can't bond to the old product. Complete removal is the only way to get a joint that stays clean and sealed. We use an oscillating tool and caulk remover to get the joint clean before we apply anything new.
