- A second bead peeling off the first
- Beads that never stuck properly
- Wide, uneven beads that look worse than the old ones
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It usually takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Greenford, 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.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Clear the area around the work
- Let us know about parking restrictions
- Keep children and pets away from the work area

Advice
Remedial sealant in Greenford, 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. New sealant only bonds to a clean, dry joint. If you are dealing with movement joints that have split or pulled away and sealant that came away because the surface wasn’t prepared, we can help, on botched or over-sealed joints, failed movement joints and shrunken worktop sealant alike.
Hard London water leaves limescale on sealant, grout and taps alike. In Greenford, remedial sealant is as much about a room looking cared for as about keeping water out.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

When something else is needed
Before you book, it’s worth knowing the limits too:
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
- Movement from fittings that aren’t supported

Where we work in Greenford
- Expansion joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Use a soft cloth, not a scourer, on silicone
- Look for stains below bathrooms now and then
- Never seal over old silicone
- Air the bathroom so the sealant can dry
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Landlord and commercial work in Greenford
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How the job changes by surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
What we’re called out for in Greenford
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
People normally contact us after spotting something like this:
- Thick, messy sealant smeared over tiles
- Movement joints that have split or pulled away
- Dark patches showing through the sealant
- Kitchen joints letting water behind the worktop
As a London address, Greenford can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Remedial sealant around Greenford
London’s water is hard, so limescale builds up on sealant, grout and fittings. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
For site and facilities teams at buildings such as Oldfield Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. For landlords with property near Greenford station, a joint that keeps failing is best fixed properly while the property is empty.

Why act early in Greenford
Ripping out a bathroom isn’t generally needed. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. 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.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Questions from Greenford
I live in a flat in Greenford. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Is parking an issue for remedial sealant in Greenford?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, usually. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
What if resealing will not fix my leak?
In that case, we tell you what we’ve found. A plumber or fitter may be needed before any new sealant goes on.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you cover Greenford?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
