Glazing & conservatory sealant in Kensal Town, Greater London
Our applicators work in Kensal Town on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly.
- Mouldy sealant around glass panels
- Failed sealant around rooflight glass
- Water running down inside the glass
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Use a gentle glass cleaner and a soft cloth
- Keep air moving in the conservatory
- Use gentle products around the joints
- Do not leave a drip for the next storm
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
About our glazing silicone in Kensal Town
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. Typical jobs include stained, discoloured glazing silicone and split or lifting silicone on glass, across glass-to-glass joints, rooflights and conservatory frames.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Kensal Town as anywhere.
You get a 12-month guarantee, the same in Kensal Town as everywhere else we work.

What else we do in Kensal Town
The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing for a typical job. In Kensal Town, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Why deal with it now?
Topping up old silicone can look like a fix, but silicone does not stick to silicone, and the leak usually returns. Cutting out and resealing properly lasts. 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.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Signs you need glazing silicone in Kensal Town
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
Common reasons people contact us are:
- Glazing silicone that has cracked or come away
- Sealant that was laid over old silicone and failed

What glazing silicone looks like in Kensal Town
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
If you live in an older home near St Thomas Kensal Town, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as St Thomas' CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
