Failed grout comes out with a grout saw or oscillating tool, down to clean tile edges. We re-pack the joints with new grout and a grout float, matching the existing color where possible.
Black spots in the grout lines get treated before anything new goes in. If the mold has reached the backer board, we will show you and explain what the repair actually needs.
Interior corners, the pan joint, and the valve plate get 100% silicone caulk, not siliconized acrylic. Silicone stays flexible, bonds to tile and glass, and holds up to daily steam and hard water.
We check the drain connection and the shower pan while we are in there. A drain that is not sealed to the pan liner will keep leaking no matter how good the caulk line looks.
Before we leave, we walk you through the finished work and tell you exactly how long to wait before using the shower. Silicone needs 24 hours. We also tell you what to watch for over the next month.
We walk the shower, check the caulk lines, tap the tile for hollow spots, and look at the pan and drain. You get a straight answer on what needs re-caulking versus what needs grout replacement. Most assessments take 15 to 20 minutes and there is no charge.
We cut out the old caulk with a razor scraper and remove failed grout with a grout saw or oscillating tool. This is the step most DIY jobs skip, and it is why their new caulk peels within a year. We take it down to clean, sound material.
The open joints get treated for mold and mildew, then dried. Silicone will not bond to a damp surface, so this step matters. We use a moisture meter on the substrate and will not seal until the reading is dry.
We pack new grout into the tile joints with a grout float, then apply a bead of 100% silicone caulk at the pan, corners, and valve plate with a caulking gun. Interior corners get caulk, not grout, because grout cracks when the walls move.
Silicone needs 24 hours to cure before the shower is used. We walk you through the finished work, show you the new seal lines, and tell you what to watch for. If anything looks off in the first 30 days, we come back.

Applies a controlled, even bead of 100% silicone at the pan, corners, and valve plate. A steady bead is what keeps water from finding a gap.
Packs new grout into the tile joints at a consistent depth. Even grout lines cure more uniformly and resist cracking better than hand-packed joints.
Removes old caulk and failed grout down to clean tile edges. This is the step that determines how well the new material bonds.
Checks that the substrate is dry before we seal. Silicone will not bond to a damp surface, so we test rather than guess.
Lets us pull and reseat the shower drain so we can inspect the pan liner connection and confirm the drain is properly sealed.
Used when we reset a shower pan, check slope, or install a new enclosure. Correct slope is what moves water to the drain instead of into the caulk line.
