Remedial sealant & repairs in Southwick, West Sussex
Failed sealant joints in Southwick need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Movement joints that have split or pulled away
- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
What happens if it’s left?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Homes in smaller places like Southwick can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Why book with us
- Any old sealant cut out fully, not covered over
- Colour agreed with you before work begins
- Trusted Arbo and Everbuild sealants
- Fully insured
About our remedial sealant in Southwick
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. If you’re dealing with kitchen joints letting water behind the worktop and sealant peeling off a dusty or damp surface, we can put it right.
In and around Southwick, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
Each job carries a 12-month guarantee, whatever its size.

Bathrooms and kitchens in Southwick
Southwick is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For landlords with property near Southwick station, botched sealant from a previous quick fix is easier to strip out between tenants. If you look after a building such as Eastbrook Primary Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St Michael and All Angels Church, walls and floors in older homes can move, and sealant and grout show it first.

Different surfaces, different methods
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Work for landlords, hotels and businesses
Landlords and agents in Southwick can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

How the visit works
At the end, we look at the finished work together. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. A visit to Southwick is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Southwick questions
Is Southwick in your area for remedial sealant?
Yes, Southwick is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Do you cover smaller places like Southwick?
Yes. Southwick is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What happens if the problem is the tray or the plumbing?
Then we explain what we have found. A plumber or fitter may be needed.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Can you strip sealant from an acrylic tray safely?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Have loose fittings fixed before resealing
- Do not add new sealant on top of old
- Look for stains below bathrooms now and then
- Air the bathroom so the sealant can dry
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
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.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A tray or bath that is cracked
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
