Professional remedial sealant in and around Copthorne, with old sealant always removed completely.

Remedial sealant in Copthorne, done properly
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. Common call-outs are for over-sealed joints coming away and smears and lumps from a botched reseal, on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant.
Smaller places like Copthorne still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
All our work comes with a one-year guarantee.

When to call us in Copthorne
One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
Common reasons people contact us include:
- Thick, messy sealant smeared over tiles
- Beads that never stuck properly
- Kitchen joints letting water behind the worktop
- Over-sealed joints coming away
Letting a property close to Gatwick Airport station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. Parking around Copthorne is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Copthorne homes and their sealant
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. There are hotels and other places to stay in and around Copthorne. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you look after a building such as Fairway Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes. In the older streets around St John's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What else we do in Copthorne
Why deal with it now?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Around Copthorne, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why book with us
- White, clear, grey or another colour, product permitting
- A 12-month guarantee on all work
- We agree the colour with you first
- Any old sealant cut out fully, not covered over

Questions from Copthorne
Will you come out to Copthorne?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Gatwick Airport station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
What happens if the problem is the tray or the plumbing?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
My shower still leaks after a reseal. Can you sort it?
Yes, generally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
How do I get a quote for remedial sealant in Copthorne?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
How the job changes by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep movement joints clear of mortar and paint
- Keep an eye on the ceiling below the bathroom
- Ask why a joint failed before redoing it
- Check trays and worktops don’t move
Do not let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
