Bathtub Caulking
The seam where the tub meets the tile is the first place a bathroom starts to look tired: black mold, mildew and grime collect there no matter how clean the tub is. When we refinish a bathtub, that seam gets redone as part of the job — and it ends up sealed under the new enamel, with no caulk line to see.

Caulking that disappears under the finish
Most caulk jobs are done last, on top of everything. We do it the other way around — and that’s what makes the difference.
- Old caulk comes out. After the tub is stripped and prepped, we remove the old silicone and clean the joint between the tub and the wall.
- A fast-curing elastic sealant goes in. We use a professional sealant made for door and window joints — it sets in minutes and stays flexible for years, so it moves with the tub instead of cracking.
- Enamel is poured over it. The sealant is covered by the new pour-on enamel along with the rest of the tub. The seam becomes part of the finish: one smooth, continuous surface from the wall onto the tub.

What you get instead of a bead of silicone
- No visible caulk line — the seam is under the enamel, so there’s nothing to yellow, peel or collect dirt.
- Sealed against water — the elastic sealant plus the enamel on top close the gap completely. Water that gets behind a tub ends up at the neighbors below; this is how you avoid it.
- Stays flexible — a tub moves slightly with temperature and weight. A rigid filler cracks; this sealant doesn’t.
- Resists mold and mildew — a smooth, non-porous surface where a caulk bead used to be, cleaned the same way as the tub.
- Done in the same visit — adds a few minutes to the job, no extra appointment.
Caulking is part of every bathtub refinishing job — at no extra charge. We don’t offer it as a separate service: the whole point is that the seam gets sealed under the new enamel, and that only works when the tub is being refinished.
