- A shower that leaks however often it’s resealed
Remedial sealant in Wallington
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you phone 0345 464 0079 or send us an email, along with when it was last resealed. We are often asked to deal with thick, messy sealant smeared over tiles and black mould underneath the bead, on botched or over-sealed joints, leaking tray & enclosure joints and expansion joints.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Wallington homes and their sealant
London’s water is hard, so limescale builds up on sealant, grout and fittings. Wallington 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 look after a building such as Holy Trinity CofE Junior School, we reseal washrooms and kitchens in schools and businesses as well as homes. As a London address, Wallington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Common problems we fix in Wallington
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.
People generally contact us after spotting something like this:
- Black mould underneath the bead
- Products that weren’t meant for the joint
- Kitchen joints letting water behind the worktop
- Wide, uneven beads that look worse than the old ones
In the older streets around Church of the Holy Trinity, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Sealant in an older building that needs testing for asbestos first
- A cracked shower tray or bath (that needs repair or replacing)
- Plumbing leaks behind walls or under trays
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most joints, depending on how much old sealant has to come out. In Wallington, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Why it’s worth doing now in Wallington
Another bead over the top will not fix a failed joint. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
