Updated 2026-08-02 · Sources verified 2026-07-20
Thinking about a tub/shower caulking repair in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.
Do you need a permit?
Orange County and the City of Orlando run separate permit offices with separate portals — and your mailing address alone doesn't tell you which one covers your home. Check which permit office covers your address →
Key facts before you start
- Fill the tub with water BEFORE caulking: the tub sinks/flexes under water weight, so sealing at max flex keeps the new joint from tearing on first use (GE).
- Remove 100% of old caulk — new sealant will not adhere over old material or residue; scrape remnants, wipe with isopropyl alcohol (not soap), and let the surface dry completely (moisture under fresh sealant ruins adhesion and invites mold).
- Use 100% silicone kitchen-and-bath formula for tub/shower joints (waterproof, permanently flexible, 10-yr+ mold-free protection); note paint will never stick to 100% silicone, even primed — spec siliconized acrylic (e.g., DAP Kwik Seal Ultra) only where paintability matters.
- Water-ready times are conditional, not universal: GE Advanced Silicone 2 is water-ready in 30 min ONLY at max 3/16-in bead, >=65F and >=50% humidity — otherwise keep water off 8 hrs (full cure 24 hrs). Siliconized acrylic needs 4 hrs before water, 24 hrs ideally.
- Tool/smooth the bead immediately after laying it and work in sections — silicone skins fast; remove masking tape while caulk is still wet.
- For joints deeper than 1/4 in or wider than 1/2 in, insert foam backer rod first — it prevents 3-point adhesion (sealant bonding to the joint bottom), which causes premature splitting.
