Glazing silicone in Clapton, done properly
Across Clapton, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. We are often asked to deal with water running down inside the glass and leaks where conservatory glass meets the frame, across rooflights, glass-to-glass joints and shower screens.
Homes in small places like Clapton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee in Clapton and across West Berkshire.

For landlords and businesses
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What happens if it’s left?
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Older cottages and farmhouses around Clapton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Windows and doors in Clapton
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Benham Park (about 3.9 miles south-east) nearby, there’s older building stock in the area around Clapton 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.
If you live in an older home near Church of St Swithin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Other services in Clapton
Different surfaces, different methods
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Common problems we fix in Clapton
Glass and frames expand and contract with the temperature, and they do not move by the same amount. In time, the sealant splits or pulls away.
People generally contact us after spotting one of these:
- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
- Water running down inside the glass
- Leaking glazing joints on a rooflight
If you let a flat or house near Kintbury station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Your questions about glazing silicone in Clapton
Do you cover smaller places like Clapton?
Yes, Clapton is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Kintbury station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you guarantee glazing sealant work?
Our 12-month guarantee covers every job.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.
Can you fix a leaking conservatory?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Can you match the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How the visit works
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work normally takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Clapton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Each joint is checked and, where possible, water-tested.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed

How to look after the new joints
After the cure time, these simple habits help:
- Clear the conservatory gutters regularly
- Look over the glazing joints once a year
- Keep scrapers and blades away from the silicone
- Clean glass with a mild cleaner and a soft cloth
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
When something else is needed
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- A roof that has moved or dropped
- Rotten or badly damaged frames
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
