Remedial sealant in Chingford Mount, done properly
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. Typical jobs include sealant applied over old sealant that has lifted and sealant peeling off a dusty or damp surface, on shrunken worktop sealant, leaking tray & enclosure joints and failed movement joints.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Chingford Mount are no different.
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.

The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. In Chingford Mount, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Your questions about remedial sealant in Chingford Mount
Can worn sealant in a flat in Chingford Mount cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
I let a flat near Highams Park station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
How long does the work take?
A little longer than a standard reseal. Most jobs take a few hours.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Do you guarantee remedial jobs?
Yes, with our one-year guarantee. If we’ve pointed out another problem, getting it fixed helps the new joint last.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you remove sealant that is been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
Are you fully insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
What the job involves on each surface
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
What we cannot put right
We will always be straight with you, so here’s what new sealant will not do:
- Water damage behind tiles that needs a tiler
- Cracks in the fitting rather than the joint
- Leaks from a shower valve, waste or pipework (a plumber’s job)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on
- Mouldy bath & shower sealant

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Looking after it afterwards
After the cure time, these simple habits help:
- Deal with small splits early
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
- Keep bleach and abrasives off the bead
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
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.
Bathrooms and kitchens in Chingford Mount
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps.
Schools such as Lime Academy Larkswood are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. If you live in an older home near St Edmund's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Do you need remedial sealant in Chingford Mount?
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
If you can see any of these, it’s time to have the joints looked at:
- Sealant peeling off a dusty or damp surface
- A second bead peeling off the first
- Dark patches showing through the sealant
- Caulk or the wrong sealant used in a wet area
As a London address, Chingford Mount can be tricky for parking: let us know about parking bays, permits or a driveway.
