- A shower that leaks however often it’s resealed
Remedial sealant for homes and businesses in Herne Bay
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. We work on mouldy bath & shower sealant, expansion joints and failed movement joints, and the jobs we see most are smears and lumps from a botched reseal and products that weren’t meant for the joint.
Around Herne Bay, it’s mostly busy family bathrooms and kitchens, which is hard on sealant and grout. Black mould along the bath, a lifting bead by the sink or crumbling grout in the shower are the usual signs.
Every job comes with a one-year guarantee.

Common problems we fix in Herne Bay
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. At that point it has to come out.
The most common problems we see are:
- Kitchen joints letting water behind the worktop
- Wide, uneven beads that look worse than the old ones
- Decorators’ caulk around a bath or shower
- A second bead peeling off the first
Rented homes near Herne Bay station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in Herne Bay
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Air the bathroom so the sealant can dry
- Use a soft cloth, not a scourer, on silicone
- Ask why a joint failed before redoing it
- Report a tray that rocks or a worktop that lifts
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Honest limits
In fairness, some problems need a different trade:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
- Tiles that have come away from the wall
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
