Caulking and sealing across San Diego County

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. A caulk job done right lasts 10+ years; one done in a hurry starts peeling within a season.

What do homeowners ask about Caulking?

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.

When should I re-caulk a bathroom shower or tub?

Re-caulk as soon as you see cracking, peeling, or black mold that won't scrub clean. Mold in the caulk line means water is already wicking behind the tile. Left too long, that moisture causes drywall rot and tile to pop loose. A bathroom re-caulk is one of the cheapest repairs on the list; the water damage it prevents is not.

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.

What's the difference between caulk and grout?

Grout fills the joints between tiles and is rigid. Caulk is used at changes in plane, where the tub meets the tile, where the floor meets the wall, because those joints move slightly with temperature and humidity. Using grout at those joints is a common mistake; it cracks within a year.

How long does a caulk job last?

A silicone caulk job done with proper prep in a bathroom should last 10–15 years. Exterior caulk exposed to UV and temperature swings typically lasts 5–10 years. We use products rated for the specific exposure.
