Common Sealant Problems We Fix
Black mould or leaking shower sealant
Old silicone in bathrooms and kitchens can leak, peel or grow mould. We remove it completely and reseal with a suitable sanitary-grade silicone.
Draughty or wet window perimeters
Failed mastic around window and door frames lets in draughts and water. We strip and reseal the perimeter to match the frame and substrate.
Cracked or missing external mastic
Sun, frost and movement break down external sealant. We remove the failed material and reseal with a product suited to the exposure and joint.
Builders' snagging lists
We work with builders and site managers to complete mastic and sealant snagging on new-build and refurbishment projects.

What Customers Say
“Liam did such a brilliant job on our new bathroom. We’d had the silicone done already but weren’t happy with the finish, and he came in and sorted it all out for us. It looks so much neater now and has made a massive difference to the room. Really friendly, tidy and clearly knows what he’s doing. We’ll definitely be getting him back once the shower screen and toilet are fitted. Would 100% recommend 👍 thank you so much Liam.”
Vicky Lawrenson
Bathroom reseal
“Liam was fantastic! Our kitchen fitters did a 'quick' job = so crap. Liam came, found the perfect colour match, completed the work to a high standard and even sorted out the bits the fitters claimed were fine (but obviously weren't). Will be getting him back in the summer to do the same on the outside of the house. Don't think twice about booking him”
Jane Temple
Kitchen sealant
“Excellent service provided; Liam went above and beyond nothing was too much trouble the workmanship was absolutely perfect would highly recommend!”
