Common problems we see
Peeling, shrinking caulk
As caulk ages it loses elasticity, shrinks and pulls away from the wall or floor, opening a gap that water runs straight through.
Black mould staining the seam
Mould grows in and under porous or failed caulk where moisture sits, and it can't be cleaned out — the sealant has to come out.
Soft, gummy or tacky caulk
Caulk that never fully cured, or is breaking down, stays soft and collects grime — a sign it needs to be removed and replaced.
Water leaking at a corner
Leaks at the base or corners usually mean the caulk has failed and water is escaping behind the tile or under the floor.
Our process in action
Premium mildew-resistant caulk for clean, watertight seams.
- Cut out old, mouldy or failed sealant down to a clean joint.
- Deep-clean and fully dry the joints.
- Apply premium mildew-resistant caulk and tool a clean bead.
- 1
Cut out old sealant
We remove all old, mouldy or failed caulk down to a clean joint — applying new caulk over old traps residue and fails early.
- 2
Deep-clean and dry
The joint is scrubbed of mould and residue and fully dried so the new sealant bonds to a clean surface.
- 3
Mask and apply
We mask the tile for a crisp line and apply a premium 100% silicone, mildew-resistant sealant designed for wet areas.
- 4
Tool a clean bead
The bead is tooled smooth so it presses into the joint and sheds water, then the mask is removed for a clean finish.
What you get

Local context for Southern California showers
Caulk is the flexible seal at every shower corner, seam and fixture penetration — the points where rigid tile meets movement. In Southern California's hard water, failed caulk is the single most common cause of hidden water damage, because once the seal opens, water runs straight behind the wall. Premium, mildew-resistant silicone, applied to a clean dry joint, lasts years longer than standard acrylic caulk.
What affects the price
- Linear metres of seam being caulked
- Number of corners, fixtures and penetrations
- How much old caulk needs to be removed
- Whether mould remediation behind the seam is needed
- Access around glass, benches and niches
Aftercare & maintenance
Keep the new caulk dry for the full cure time (usually 24 hours). Clean it with mild, non-abrasive products and a soft cloth. A quick wipe-down after showering prevents soap and mould build-up and keeps the seam clean.
