What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or worktop that needs refixing first
- Cracks in the fitting rather than the joint

About our remedial sealant in West Mersea
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. Typical jobs include thick, messy sealant smeared over tiles and torn expansion joints, on mouldy bath & shower sealant, leaking tray & enclosure joints and failed movement joints.
In and around West Mersea, older properties sit alongside newer ones. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Questions from West Mersea
Will you come out to West Mersea?
Yes. West Mersea is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on remedial sealant in West Mersea?
All our work, in West Mersea and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
How do I get a quote for remedial sealant in West Mersea?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
What we’re called out for in West Mersea
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Most people get in touch after spotting something like this:
- Mould trapped under a layer of silicone
- Leaks that keep coming back after resealing
- A second bead peeling off the first
- Gaps opening along the back of the worktop
Managing a site like Mersea Island School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- What the cure time is
- Which sealant they’ll use, and why
- Are they insured?
- How much experience the applicator has
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. A visit to West Mersea is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Related advice
What happens if it’s left?
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you’ll hear it from us. Homes in smaller places like West Mersea can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Why us?

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Run the fan after every shower
- Keep movement joints clear of mortar and paint
- Act on a lifting corner straight away
- Keep bleach and abrasives off the bead
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Bathrooms and kitchens in West Mersea
West Mersea is within about 2 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of St Peter and St Paul, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
