Silicone does not fail visibly.
That is what makes it a problem.
The joint between a bathtub and tile, or between a shower tray and wall, is where water exits the surface it is supposed to stay on. When the silicone at these joints is sound, water stays out. When it cracks, gaps, or loses adhesion at the edge, water finds the gap and moves behind the tile.
What happens behind the tile is not immediately visible. Moisture works into the wall. In Metro Vancouver bathrooms where the fan is also undersized or failing, the process compounds — moisture stays in the room longer, the silicone deteriorates faster, and both problems accelerate together.
By the time a homeowner notices cracked grout, a persistent musty smell that cleaning does not clear, or tiles that move slightly when pressed, the moisture has been active for some time. Resealing at the surface stage — before the wall is involved — is the job that stays small. Waiting can make it expensive.
You can check the tile bond yourself before booking. Press on the bottom row of tiles at the tub or shower. Any movement suggests moisture behind the wall. Tap the bottom tiles with a coin — a dull sound compared to the sharper sound of the tiles higher up suggests moisture has muffled the bond. These are the signs that tell you the job is still a surface job.
Where Emmassa reseals
How the work gets done
A thirty-second video makes silicone application look easy. The cut and apply part is straightforward. What those videos skip is the preparation — and preparation is where the job actually succeeds or fails. New silicone will not bond to existing silicone residue. It will not bond properly to a damp surface. A bead applied over residue or into a wet joint will fail early, and fixing a bad application costs more than doing it right the first time.
What costs more
The $399 starting price covers a standard bathtub or shower reseal without a glass enclosure, using DOWSIL sealant in clear, white, or translucent. The following will affect the price:
Scope and what falls outside it
Silicone resealing is a surface job. The wall is not opened. The job starts and finishes at the joint. Every surface Emmassa seals has a hard, impermeable backing — tile, stone, solid surface. Silicone does not belong anywhere near drywall.
If the tile bond has already been compromised — movement when pressed, a dull sound when tapped — that is structural damage that needs a different trade before any resealing makes sense. Applying new silicone over active structural moisture damage is the wrong work done in the wrong order. If that is what the job reveals, it is said plainly.
If the bathroom fan is undersized or failing, that connection gets named. A fresh seal in a bathroom with inadequate ventilation will deteriorate faster than it should. Both problems can be addressed — but they are separate jobs with separate scopes and separate prices.
