How we handle remedial sealant in Mersham
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. Common call-outs are for floor or wall movement joints that have failed and beads that never stuck properly, on shrunken worktop sealant, mouldy bath & shower sealant and leaking tray & enclosure joints.
In a village or hamlet like Mersham, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

How the visit works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. Somewhere as small as Mersham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

What remedial sealant looks like in Mersham
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you live in an older home near Church of St John the Baptist, walls and floors in older homes can move, and sealant and grout show it first. Schools such as Mersham Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Common problems we fix in Mersham
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
Any of these means the joints need attention:
- A shower that leaks however often it’s resealed
- Over-sealed joints coming away
- Gaps opening along the back of the worktop
- Decorators’ caulk around a bath or shower
Rented homes near Ashford International station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Leave it or put it right?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Around Mersham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Do not add new sealant on top of old
- Deal with small splits early
- Get the cause of a repeat leak found before resealing
- Check trays and worktops do not move
Where we’ve pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Different surfaces, different methods
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
