Bathroom re-caulking is the most overlooked preventive maintenance in LA homes — and the math on doing it right is overwhelmingly in the homeowner's favor. A $200–$485 re-caulk every 8–12 years prevents thousands of dollars of water damage and mold remediation. Here's what the work should actually cost in 2026 and what to look for in a quote.
Single shower or tub re-caulk
A single shower or tub re-caulk in LA runs $185–$345 flat-rate in 2026. The work covers total removal of the old caulk (scoring, scraping, chemically cleaning the joint), drying for 30+ minutes, and a new bead of industrial-grade mold-resistant silicone — typically GE Sanitary 100, NSI 781, or DAP Kwik Seal Plus depending on the surface.
Anything quoted significantly under $185 for a real shower re-caulk is either being done with consumer-grade silicone (won't last 8–12 years), or being done as a re-bead over old caulk (will fail in 6 months). Both are common shortcuts.
Full bathroom re-caulk (3–5 joints)
A full bathroom — shower or tub, sink, toilet base, and the floor-to-tile joint — runs $285–$485 in LA. The price reflects the multiple joints, multiple sealants (silicone for wet areas, paintable acrylic-latex for joints that get painted), and longer total visit time.
Multiple-bathroom homes are usually quoted per bathroom with a small discount for the second and third — typically 10% per additional bathroom on the same visit.
What you're paying for
Roughly 30% of the price is materials and disposable supplies (industrial-grade sealant runs $7–$12 per tube; we use 2–4 tubes per bathroom). 60% is labor — proper removal, prep, and tooled bead application takes 60–90 minutes per bathroom done right. 10% is overhead, insurance, license maintenance, and the warranty stand-behind.
When a quote comes in significantly below $185 for a single shower, the math has to give somewhere — usually it's labor (rushed prep, no removal of old caulk) or materials (consumer-grade silicone instead of industrial mold-resistant).
Warning signs of a job that won't last
First, no visible removal of old caulk before the new bead. Old caulk has to come off — new caulk doesn't bond to weathered or contaminated caulk. Watch for the old caulk in the trash bag at the end of the visit.
Second, a bead applied on a wet or freshly cleaned joint. The joint has to dry 30+ minutes after cleaning before the new bead — moisture trapped under the bead causes adhesion failure within months.
Third, a tooled bead that looks lumpy or inconsistent. A properly tooled bead is smooth, slightly concave, and uniform. Lumpy or stringy beads come from mud-tooling instead of finger-tooling with a wet finger or a dedicated caulk tool.
