Leaves Green Remedial Sealant
Problem with your failed sealant joints in Leaves Green? We remove the old material, prepare the joints and seal them properly.
- Repeat leaks from the same joint
- Torn expansion joints
- Sealant applied over old sealant that has lifted
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Sealant in an older building that needs testing for asbestos first
- Cracks in the fitting rather than the joint

About our remedial sealant in Leaves Green
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. We work on shrunken worktop sealant, failed movement joints and expansion joints, and the jobs we see most are caulk or the wrong sealant used in a wet area and torn expansion joints.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Leaves Green, remedial sealant is as much about a room looking cared for as about keeping water out.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Why deal with it now?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. 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.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Full insurance on every job
- A 12-month guarantee on all work
- An ARBOMaster approved applicator
- Over 20 years’ experience

For landlords and businesses
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. In Leaves Green, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Clear the area around the work

Common problems we fix in Leaves Green
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
The problems people generally mention when they call include:
- Decorators’ caulk around a bath or shower
- Sealant that came away because the surface wasn’t prepared
- Sealant applied over old sealant that has lifted
- Kitchen joints letting water behind the worktop
As a London address, Leaves Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What to look for in a quote
- Who does the work, and how experienced they are
- What happens if the job turns out different
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
Remedial sealant around Leaves Green
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
In the older streets around Keston Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you let a flat or house near Hayes (Kent) station, a joint that keeps failing is best fixed properly while the property is empty.

Leaves Green questions
I live in a flat in Leaves Green. 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. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Is parking a problem for a job in Leaves Green?
Parking in Leaves Green, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How long does remedial resealing take?
A little longer than a standard reseal. Most jobs take a few hours, and we confirm the time with your quote.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
