About our remedial sealant in Keymer
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. We’re often asked to deal with a second bead peeling off the first and worktop sealant that has shrunk and split, across leaking tray & enclosure joints, shrunken worktop sealant and expansion joints.
Around Keymer, you’ll mostly find houses and bungalows, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Every job is covered by a one-year guarantee.

What affects the quote in Keymer
For a quick quote, just ask. The main things that affect it are:
- Whether there’s mould to deal with
- Which sealant suits the joint
- When we can work, for business premises
- Access and height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- Where the job is, and your postcode
- What’s wrong with the joints now
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep an eye on the ceiling below the bathroom
- Keep the room well ventilated
- Check trays and worktops do not move
- Find out why the sealant failed first
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, call 0345 464 0079 or drop us an email.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Different surfaces, different methods
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before we reseal.
How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Parking around Keymer is normally 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.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
How to prepare
- Clear the area around the work
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Remedial sealant in Keymer: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. Keymer has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you live in an older home near St Cosmas and St Damian Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Hassocks station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Keymer is about 2 miles south of Burgess Hill, in West Sussex. Keymer gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our West Sussex coverage runs to 371 places, Keymer among them. For nearby work, see our Brighton page (6 miles or so).
Jobs for remedial sealant in BN6 works the same way as everywhere else we cover. You will find streets such as Flowers Close, The Quadrant and Kymer Gardens, all of which we cover. If you are just outside Keymer, we cover Hassocks (1 mile west), Ditchling (1 mile east), Clayton (1 mile south-west), Hurst Wickham (1 mile north-west) and Westmeston (2 miles south-east). Further out, we also cover Crawley (13 miles north), Horsham (13 miles north-west), Worthing (14 miles south-west), Haywards Heath (5 miles north), East Grinstead (15 miles north) and Shoreham-by-Sea (8 miles south-west).
Near you in Keymer
Locally, jobs take us to homes and businesses close to The Greyhound Public House and Downlands Community School and the streets around them. The nearest railway station is Hassocks station, roughly 0.5 miles west. A little further out are The Dene Hospital (3.2 miles north-west) and Clayton Castle (1.2 miles south-west). The countryside around Keymer includes Ditchling Beacon and Bedelands Farm Nature Reserve.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Keymer questions
Do you cover smaller places like Keymer?
Yes, Keymer is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Hassocks station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and let us know what needs doing and where.
What we can’t put right
It helps to know what we cannot do:
- Cracks in the fitting rather than the joint
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A leaking trap, valve or supply pipe
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
Common problems we fix in Keymer
Movement tears sealant that isn’t designed for it. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Common reasons people contact us are:
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
- Thick, messy sealant smeared over tiles
- Sealant that came away because the surface wasn’t prepared
Schools such as The Windmills Junior School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
