Common Problems We Fix
Black mould and water leaks around shower trays
01Failed or mouldy shower silicone allows water to seep behind tiles and rot ceiling plasterboard downstairs. We strip out 100% of the old bead, treat the joint with biocides, and tool fresh trade-grade sanitary silicone.
Unreliable handymen who don't turn up or bodge the finish
02Tired of tradesmen who don't answer messages or leave messy, wavy silicone smeared over tiles? Liam deals with you directly, turns up when agreed, and leaves your home spotless.
Cold draughts and whistling winds around window frames
03Perished exterior window mastic lets cold air and rain into your cavity walls. We install closed-cell backing rods and low-modulus neutral silicone that lasts 15 to 20 years.
Crumbling grout lines in shower corners
04Rigid grout in corners cracks under normal tray movement. We rake out cracked grout and seal with flexible sanitary silicone, with optional full wall regrouting.

“Liam did a great job sealing our bathroom. It was left in a mess by the previous owners but Liam came and swiftly cut out the old sealant and resealed it beautifully in only a couple of hours. The bathroom has now been transformed! Would highly recommend and really reasonable price.”
