Remedial Sealant in Withdean
Failed sealant joints in Withdean need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Leaks that keep coming back after resealing
- Black mould underneath the bead
- Thick, messy sealant smeared over tiles
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Remedial sealant in Withdean
Movement and expansion joints fail when the sealant cannot stretch. 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, leaking tray & enclosure joints and shrunken worktop sealant, and common reasons people get in touch are dark patches showing through the sealant and thick, messy sealant smeared over tiles.
Homes around Withdean range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the quote in Withdean
We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- The number of rooms or windows
- The number and length of the joints
- How easy the joints are to reach
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- Where the property is
- What’s wrong with the joints now
- Whether it’s a home or a business

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for most joints, depending on how much old sealant has to come out, and we tell you how long to leave it before we go. In a smaller place like Withdean, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to 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 water getting in
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

What else we do in Withdean
What we’re called out for in Withdean
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing sets the depth and stops that.
Signs it’s time to call us include:
- Torn expansion joints
- Kitchen joints letting water behind the worktop
- Sealant that came away because the surface wasn’t prepared
- A second bead peeling off the first
For landlords with property near Preston Park station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- Whether you can choose the colour
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- What happens if the job turns out different
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Older mastics that may need an asbestos check before removal
- Water damage behind tiles that needs a tiler
- Cracks in the fitting rather than the joint
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Expansion joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
Withdean homes and their sealant
Withdean is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Withdean 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.
Managing a site like St Bernadette's Catholic Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St John the Evangelist's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Different surfaces, different methods
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. We’ll reseal and tell you if extraction looks to be the issue.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Don’t wait for a small gap to become a leak
- Don’t add new sealant on top of old
- Run the fan after every shower
- Find out why the sealant failed first
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
