Leaking Tiled Shower Repairs - Greater Wellington
Small leak, big trouble. If your tiled shower is leaking, dripping into subfloors, or growing mould, it won't fix itself. We rebuild and waterproof tiled showers properly - leak-free and built to last - across Wellington, Lower Hutt, Upper Hutt, Porirua and the Kāpiti Coast.
Does your tiled shower leak or need constant repairs?
We specialise in full tiled-shower rebuilds that fix the cause, not just the symptoms. Patch jobs rarely last; when membranes fail or grout cracks, water gets into framing and subfloors. Our team diagnoses the leak, rebuilds correctly, and waterproofs to NZ standards for a durable, healthy bathroom.
Signs Your Shower is Leaking:
- Persistent dampness or unexplained wet patches near the shower.
- Musty odours, mould on grout or walls.
- Cracked/loose tiles, missing grout, swollen skirtings or architraves
- Water stains on nearby walls/ceilings or rooms below
Why You Should Act Now:
- Leaks quickly spread into timber, linings and subfloors
- Mould and mildew harm indoor air quality.
- Property value takes a hit with water damage history.
- Early intervention is almost always cheaper than a full structural repair later.
