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.
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.

Had three holes in my hallway from a botched DIY attempt, different sizes, one with texture around it. He matched the orange peel texture exactly and I genuinely can't find the patches now. Priced fairly, no surprises on the invoice.
My living room wall is stucco over concrete block, two other people said no. Fix Pro came out, assessed it, had the right hardware, and mounted my 75-inch TV same day. Clean install, cables managed through the wall. Exactly what I needed.
He repainted my master bedroom and the hallway leading to it, a tricky color transition I'd been putting off for two years. Clean prep work, no drips on my oak floors, and the edges at the ceiling are straighter than when the house was built. Hired him again for the living room.
