Waterproofing & Leakage
Bathroom leakage repair without breaking tiles
Injection grouting, epoxy re-grouting and joint sealing that stop bathroom seepage without tearing up your floor, when the diagnosis allows it.
Most people dread bathroom leak repair because it usually means days of noise, dust and a bathroom out of action.
Not every bathroom leak needs demolition. If water is entering through failed tile joints or around fittings, it can often be sealed from the surface. RennovEN tells you honestly whether that will work in your case.
Signs you need this
- Damp wall outside the bathroom
- Stains on the ceiling below the bathroom
- Black or crumbling grout lines
- Damp around the WC or floor trap
The RennovEN promise
- 10-year warranty on all works
- Itemised pricing, approved before work begins
- One accountable team across every trade
- Residential specialists — homes only
Diagnosis
Why it happens
Porous cement grout
Ordinary grout cracks and absorbs water over time, letting it pass under tiles.
Gaps around fittings
Water seeps around the floor trap, WC base and pipe entries when seals fail.
Hairline tile cracks
Small cracks in floor tiles allow water into the bedding below.
