About our remedial sealant in Ruislip
The wrong product in the wrong joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on leaking tray & enclosure joints, failed movement joints and shrunken worktop sealant, and people most often call us about over-sealed joints coming away and sealant peeling off a dusty or damp surface.
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. A compact bathroom that steams up every day is hard on silicone and grout.
Every job is covered by our one-year guarantee.

What remedial sealant looks like in Ruislip
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, and it has to be cleaned off before new sealant goes in.
Homes close to St Lawrence include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Warrender Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What affects the quote in Ruislip
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- What’s wrong with the joints now
- Whether it’s a home or a business
- If someone has resealed it before
- Where the job is, and your postcode
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details, and photos are welcome.
Keeping the joints in good condition
So the new joints stay in good condition:
- Get the cause of a repeat leak found before resealing
- Clean sealant with mild products only
- Deal with small splits early
- Keep the room well ventilated
Keep the room ventilated: use the extractor or open a window after showering.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
When to call us in Ruislip
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
These are the problems we’re asked about most:
- Gaps opening along the back of the worktop
- Decorators’ caulk around a bath or shower
- Thick, messy sealant smeared over tiles
- A shower that leaks however often it’s resealed
Ruislip is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- How the joint is cleaned and prepared
- What product goes in the joint
- Are they insured?
- Whether VAT is included
What happens on the day
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job generally takes a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. For a job in Ruislip, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

What happens if it’s left?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. Removal is the only way to get at it. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Domestic, commercial and hotel work
- We leave the area clean and tidy
- White, clear, grey or coloured to suit, where the product allows
- A 12-month guarantee on all work
Ruislip questions
Is parking a problem for a job in Ruislip?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can worn sealant in a flat in Ruislip cause a leak downstairs?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you guarantee remedial jobs?
Yes. Our one-year guarantee covers the work, and we’re fully insured.
How long does remedial resealing take?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Ruislip.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or bath that is cracked
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
Should I try it myself first?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
