How we handle remedial sealant in East Mersea
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on failed movement joints, botched or over-sealed joints and leaking tray & enclosure joints, and common reasons people get in touch are leaks that keep coming back after resealing and thick, messy sealant smeared over tiles.
Around East Mersea, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
There’s a 12-month guarantee on every job, large or small.

Surface by surface
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, which we will point out.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
So the new joints stay in good condition:
- Run the fan after every shower
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
- Act on a lifting corner straight away
Keep the room ventilated: run the fan during and after showers, or open a window.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
What happens if it’s left?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Older cottages and farmhouses around East Mersea can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Questions from East Mersea
Is East Mersea in your area for remedial sealant?
Yes. Our work covers London and the South East, and East Mersea is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Do you cover smaller places like East Mersea?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you have insurance?
Yes. Full insurance covers our work.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. In a small place like East Mersea, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Let us know about parking restrictions

Related advice
What we’re called out for in East Mersea
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Most people get in touch after spotting one of these:
- Caulk or the wrong sealant used in a wet area
- Repeat leaks from the same joint
- Thick, messy sealant smeared over tiles
- Floor or wall movement joints that have failed
For an older house near a landmark such as Parish Church of St Edmund King and Martyr, walls and floors in older homes can move, and sealant and grout show it first.

Remedial sealant in East Mersea: local notes
East 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, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Alresford station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
