How we handle remedial sealant in Kensal Green
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. If you have a second bead peeling off the first and sealant that came away because the surface wasn’t prepared, we can put it right, whatever the surface.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Kensal Green more than a cosmetic job.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Kensal Green: your questions answered
Do you work for landlords with property near Kensal Green station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can parking be tricky for a visit in Kensal Green?
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.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long does the work take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. You will know the timing when we quote.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before we start.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
How much does remedial sealant cost in Kensal Green?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.
When something else is needed
It helps to know what we cannot do:
- Failed tanking or loose tiles behind the sealant
- Older mastics that may need an asbestos check before removal
- Movement from fittings that are not supported
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Failed movement joints
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Act on a lifting corner straight away
- Keep bleach and abrasives off the bead
- Keep the room well ventilated
- Get the cause of a repeat leak found before resealing
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, phone 0345 464 0079 or send us an email.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Why act early in Kensal Green
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. 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 look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, 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 a London area like Kensal Green, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We protect the surfaces around the joint.
- 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.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about any water getting in

Related advice
Signs you need remedial sealant in Kensal Green
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Common reasons people contact us are:
- Movement joints that have split or pulled away
- Sealant peeling off a dusty or damp surface
- Leaks that keep coming back after resealing
- Gaps opening along the back of the worktop
As a London address, Kensal Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- How hidden problems are handled
- Is VAT in the price?
- How the colour is chosen
- Whether all the old sealant comes out first
What remedial sealant looks like in Kensal Green
London’s water is hard, so limescale builds up on sealant, grout and fittings. There are hotels and other places to stay in and around Kensal Green. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Homes close to St Martin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Kensal Green station, a joint that keeps failing is best fixed properly while the property is empty.

Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.

Some leaks around windows come from the wall or the window itself. If the frame joint isn’t the cause, we’ll say so.
