About our glazing silicone in Church End
We do not replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that’s often where the water gets in. We’re often asked to deal with leaking glazing joints on a rooflight and mouldy sealant around glass panels, across shower screens, glass balustrade bases and glass-to-frame joints.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Church End is something to talk through when you book.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How to look after the new joints
To keep the joints looking good and working properly:
- Keep conservatory gutters clear of leaves
- Use gentle products around the joints
- Clean glass with a mild cleaner and a soft cloth
- Keep air moving in the conservatory
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most jobs and we leave things clean and tidy. In Church End, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Is parking a problem for a job in Church End?
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 do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.

Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Glazing silicone in Church End: local notes
Historic houses like Heath Hall (about 2.1 miles south-east) are a reminder that the area around Church End has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Homes close to St Margaret's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. As a London address, Church End can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Pardes House Grammar School, larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
