Remedial sealant & repairs in Winton, East Sussex
Remedial sealant across Winton and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Over-sealed joints coming away

- Sealant peeling off a dusty or damp surface
How we handle remedial sealant in Winton
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you have movement joints that have split or pulled away and worktop sealant that has shrunk and split, we can put it right, on leaking tray & enclosure joints, shrunken worktop sealant and failed movement joints alike.
Around Winton, it’s houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
Your job is guaranteed for a year, as with all our work.

Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Winton and across East Sussex. We can quote a run of properties together, and we’re fully insured for the work.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
When something else is needed
It helps to know what we cannot do:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

What affects the quote in Winton
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The size of the job
- When we can work, for business premises
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
To help us quote quickly, let us know:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- How many joints, rooms or windows are involved
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.
Other services in Winton
How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Bathrooms and kitchens in Winton
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as Alfriston School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St. Andrew include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Berwick (Sussex) station, a joint that keeps failing is best fixed properly while the property is empty.

Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Around Winton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Winton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
- Clear the area around the work

Winton: your questions answered
Can you do remedial sealant in Winton?

Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
My shower still leaks after a reseal. Can you sort it?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you remove sealant that is been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
