Glazing silicone in Kew: local notes
With historic houses such as Kew Palace (about 0.7 miles west) nearby, there’s older building stock in the area around Kew as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, Kew can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Chiswick station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Kew is about 2 miles south of Acton, in Greater London. Our applicators cover glazing silicone for homes and businesses in Kew and nearby, as part of our work across Greater London.

Glazing silicone in Kew, done properly
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We find the joint that is letting water in and renew it, and if it’s something sealant cannot fix, we will tell you. Typical jobs include black or yellowed silicone on glass joints and new silicone smeared over old sealant, across shower screens, glass-to-frame joints and glass balustrade bases.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking, and access in Kew is something to talk through when you book.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

When to call us in Kew
The wrong sealant is a common cause. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Most people get in touch when they notice something like this:
- Mouldy sealant around glass panels
- Water tracking down the inner face of the glass
- New silicone smeared over old sealant
- Silicone pulling away from the glass
For site and facilities teams at buildings such as Grove Park Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- How much experience the applicator has
- What guarantee comes with the work
- How hidden problems are handled
- What the cure time is
Why act early in Kew
Resealing cannot fix a failed unit or a cracked panel. We say so plainly, so you can call the right trade. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Kew.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What else we do in Kew
What the job involves on each surface
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Structural problems with a conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
- A frame that needs repairing or replacing
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Rooflights
- Glass-to-frame joints
- Glass-to-glass joints
- Glass balustrade bases
- Conservatory frames
- Shower screens
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In Kew, 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.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Advice
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Questions from Kew
Is parking an issue for glazing silicone in Kew?
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 Chiswick station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Kew.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you cover Kew?
Yes, we do. Our applicators work in Kew, and the service is the same as everywhere else.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long does glazing silicone take?
Typically it takes a few hours for most jobs. Bigger jobs take longer, and we’ll say how long yours will take.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep air moving in the conservatory
- Use gentle products around the joints
- Stick to mild cleaners on glass
- Do not leave a drip for the next storm
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
