Bathroom Waterproofing and Mould Proofing in Newmarket & GTA

Tile and grout look waterproof, but they are not. Grout lets water through slowly, and over time that water soaks into whatever is behind it. If there is only drywall or wood back there, the damage stays hidden until it shows up as a stain on the ceiling below, loose tiles or a musty smell.

By the time a leak shows, the repair usually means taking out the tile you paid for. Waterproofing done properly the first time is what lets you enjoy your new bathroom without wondering what is happening behind the walls.

In a shower, waterproofing is not an extra. It is the job. Everything else sits on top of it.

Before any tile goes on, we build a continuous waterproof layer, called a membrane, over the shower walls and floor. It works like a raincoat for the room: water that gets past the tile and grout stops at the membrane and runs to the drain instead of into your walls.

The details are where leaks usually start, so that is where we take the most care: the corners, the seams, the shower niche, the bench, the valve and the drain itself. The shower floor is sloped to the drain so water never sits, and we protect the bathroom floor where water splashes around the tub and the vanity.

We use the latest methods and materials for all of it, and only premium ones.

Mould grows where moisture stays. Good waterproofing keeps moisture out of the walls and floor; good airflow clears it from the room. That is why a renovation is the right moment to look at ventilation too: our licensed electricians can install a new exhaust fan that clears the steam after a shower.

Taking out an old tub surround or tiled shower is also the best chance to see what is behind it. If there is damage behind the old walls, this is the time to deal with it properly, before the new bathroom covers it up.

Our own team does the waterproofing, never a subcontractor, and every renovation comes with our 10-year written warranty. Homeowners in Newmarket and across the GTA get the same careful work behind the tile as on the surface. In a Google review, Max F. described Rexos as “caring a lot about details and that’s why the finishing is awesome.”
