Bathroom Waterproofing Melbourne

Opal Caulking Services provides bathroom waterproofing across Melbourne. We install membranes before tiling and seal the wet-area joints once the tiles are down, so one team looks after keeping water out from start to finish.

What Our Bathroom Waterproofing Covers

We waterproof the areas of a bathroom most exposed to water:

Shower floors and walls
Bathroom floors, including around floor wastes
Bath hobs and surrounds
Wall-to-floor junctions and internal corners
Penetrations for taps, mixers and pipes
Final silicone sealing of wet-area joints after tiling

Our Bathroom Waterproofing Process

We start by checking the surface is clean, sound and ready for waterproofing. Junctions, corners and penetrations are treated first, because these are where waterproofing most often fails.

The membrane is then applied to the floor and wall areas that need it and left to cure before tiling begins. We coordinate timing with your tiler or builder so the project keeps moving.

Once the tiles are in, we can return to seal the wet-area joints with mould-resistant silicone, completing the job from membrane to finish.

They explained the work clearly, arrived when they said they would and delivered a very clean finish. Would definitely use them again.

 Trustindex verifies that the original source of the review is Google. We had Opal Caulking Services redo the silicone in our bathroom and the result was excellent. The lines are clean and neat, and the finish looks much better than before. They were also tidy and easy to deal with. Highly recommend.
