Remedial sealant in Kensal Rise, done properly
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. If you’re dealing with over-sealed joints coming away and a shower that leaks however often it’s resealed, we can put it right, whatever the surface.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Kensal Rise are no different.
Our work is backed for twelve months, in Kensal Rise and everywhere else we cover.

Remedial sealant in Kensal Rise: local notes
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.
In the older streets around Church of St John the Evangelist, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Kensal Rise is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Kensal Rise is about 1 mile south-west of Kilburn, in Greater London. Every kind of property in Kensal Rise can book us for remedial sealant. The work is guaranteed for a year. Our Greater London coverage runs to 764 places, Kensal Rise among them. London is on our list too, around 6 miles away.
Here we cover the W10, NW10 and NW6 postcode area for remedial sealant. You will find streets such as Hazel Road, Hiley Road and Kempe Road, all of which we cover. If you are just outside Kensal Rise, we cover Kensal Green (1 mile west), Kilburn (1 mile north-east), Queen's Park (1 mile east), North Kensington (1 mile south) and Kensal Town (1 mile south-east).

Landmarks near Kensal Rise
We work in homes and buildings around Paradise by Way of Kensal Green pub, Queens Park Community School and Brondesbury College, among other places. Kensal Rise has its own railway station: Kensal Rise station. A little further out are Brent Museum and Archives (1.1 miles north-west) and Westfield London (1.8 miles south). For a walk, there’s The Long Water and Campden Hill.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Run the fan after every shower
- Get the cause of a repeat leak found before resealing
- Never seal over old silicone
- Check ceilings under showers for marks
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Common problems we fix in Kensal Rise
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
People usually contact us when they notice one of these:
- Torn expansion joints
- A second bead peeling off the first
- Beads that never stuck properly
- Dark patches showing through the sealant
Schools such as Ark Franklin Primary Academy are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
What to look for in a quote
- Are they insured?
- Whether VAT is included
- The length of the guarantee
- Whether all the old sealant comes out first
What happens if it’s left?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Kensal Rise, the repair is bigger than a sealant job.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Questions from Kensal Rise
Is parking an issue for remedial sealant in Kensal Rise?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work for landlords with property near Kensal Rise station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you offer different sealant colours?
In most cases you can choose. We’ll explain which colours are available and agree one before we start.
What if the leak isn’t the sealant?
You’ll hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
How long will it take to strip and reseal the joint?
The number of joints and layers decides it. We’ll tell you before any work starts.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. In a London area like Kensal Rise, 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.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Clear items away from the joints we are working on
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Sealant in an older building that needs testing for asbestos first
- Plumbing leaks behind walls or under trays
- Water damage behind tiles that needs a tiler
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
Different surfaces, different methods
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
