Glazing silicone for homes and businesses in Kensington
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. If you’re dealing with leaks where conservatory glass meets the frame and black or yellowed silicone on glass joints, we can help, on conservatory frames, glass balustrade bases and shower screens alike.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
You get a 12-month guarantee, the same in Kensington as everywhere else we work.

What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. Failed sealant there lets water collect.
Landlords, agents and businesses in Kensington
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What affects the cost of glazing silicone
You’ll get a clear quote before any work starts. It takes into account:
- Any working-time requirements on site
- Mould in or behind the old joints
- How easy the joints are to reach
- The product the joint needs
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
To make quoting easier, let us know:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Structural problems with a conservatory roof
- Frames that have decayed or split
- Water coming through the roof rather than a sealant joint
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Glass-to-glass joints
- Conservatory frames
- Rooflights

Kensington questions
I let a flat near Kensington Olympia station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you cover Kensington for glazing silicone?
Yes, Kensington is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Is the work guaranteed?
Our 12-month guarantee covers every job, glazing sealant included.
How long does glazing silicone take?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Your quote will say how long we expect yours to take.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
Do you fit new glass or sealed units?
That’s not something we do. A misted unit has failed inside and needs replacing by a glazier.
Kensington homes and the weather
Historic houses like Leighton House (about 0.1 miles south) are a reminder that the area around Kensington has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
Rented homes near Kensington Olympia station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. As a London address, Kensington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Leave it or put it right?
You do not need new glazing because the sealant has gone. Sound glass and frames usually just need resealing. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Kensington.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours for most jobs, depending on the amount of work. In Kensington, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- 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.
Preparing for the visit
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Advice
When to call us in Kensington
Silicone won’t bond to a dirty surface. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
Keep an eye out for these signs:
- Water running down inside the glass
- Failed sealant around rooflight glass
- Cracked silicone between glass panels
- Water escaping where a screen meets the wall
Schools such as St Barnabas and St Philip's CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- What the cure time is
- How the colour is chosen
- How much experience the applicator has
- Is VAT in the price?
