Remedial sealant & repairs in Westmarsh, Kent
We cover Westmarsh for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Sealant applied over old sealant that has lifted
- Movement joints that have split or pulled away
- A shower that leaks however often it’s resealed
Keeping the joints in good condition
So the new joints stay in good condition:
- Use a soft cloth, not a scourer, on silicone
- Find out why the sealant failed first
- Check ceilings under showers for marks
- Deal with small splits early
Keep the room ventilated: use the extractor or open a window after showering.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Remedial sealant in Westmarsh
The wrong product in the wrong joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. If you’re dealing with beads that never stuck properly and a second bead peeling off the first, we can help, on expansion joints, botched or over-sealed joints and shrunken worktop sealant alike.
Around Westmarsh, it’s houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Remedial sealant around Westmarsh
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Minster station, a joint that keeps failing is best fixed properly while the property is empty.

What affects the quote in Westmarsh
There’s no set price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- The type of sealant required
- Working hours on commercial sites
- How easy the joints are to reach
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Helping us quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- How we’d reach the joints
- Where the property is
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
What happens if it’s left?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Where a wall is exposed, as many are in small places like Westmarsh, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Signs you need remedial sealant in Westmarsh
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.
It’s worth asking for a quote if you see:
- Thick, messy sealant smeared over tiles
- Torn expansion joints
- Decorators’ caulk around a bath or shower
- Kitchen joints letting water behind the worktop
In and around Westmarsh, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What insurance they hold
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- When the joint can take water or movement
What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. Somewhere like Westmarsh needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
- Clear items away from the joints we are working on
