What remedial sealant looks like in South Wimbledon
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
Schools such as Holy Trinity CofE Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. As a London address, South Wimbledon can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Remedial sealant in South Wimbledon
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you ring 0345 464 0079 or email us, and say how long ago it was last done. Typical jobs include repeat leaks from the same joint and worktop sealant that has shrunk and split, across failed movement joints, expansion joints and botched or over-sealed joints.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in South Wimbledon are no different.
Your job is guaranteed for a year, as with all our work.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on how many layers have to come out. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in South Wimbledon. A visitor permit or a nearby bay makes the visit run more smoothly.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- 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.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Why it’s worth doing now in South Wimbledon
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in South Wimbledon, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

When to call us in South Wimbledon
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Keep an eye out for these signs:
- A shower that leaks however often it’s resealed
- Sealant peeling off a dusty or damp surface
- Dark patches showing through the sealant
- Products that weren’t meant for the joint
Letting a property close to Wimbledon station? Then botched sealant from a previous quick fix is easier to strip out between tenants.
What your quote should include
- What product goes in the joint
- How the surfaces are prepared before sealing
- The length of the guarantee
- Which colour the sealant will be
Keeping the joints in good condition
After the cure time, these simple habits help:
- Act on a lifting corner right away
- Do not add new sealant on top of old
- Have loose fittings fixed before resealing
- Run the fan after every shower
Keep the room ventilated: use the extractor or open a window after showering.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

Your questions about remedial sealant in South Wimbledon
Do you work for hotels and guest houses in South Wimbledon?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near Wimbledon station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you come to South Wimbledon?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes South Wimbledon.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
