Glazing silicone for homes and businesses in Eastbury
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. We work on rooflights, glass-to-frame joints and glass-to-glass joints, and people most often call us about sealant that was laid over old silicone and failed and black or yellowed silicone on glass joints.
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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Stick to mild cleaners on glass
- Keep conservatory gutters clear of leaves
- Keep air moving in the conservatory
- Inspect the sealant on glazing annually
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.

Signs you need glazing silicone in Eastbury
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.
If you can see any of these, it’s time to have the joints looked at:
- Failed joints on frameless glass
- Failed sealant around rooflight glass
- Sealant that was laid over old silicone and failed
- Mouldy sealant around glass panels
Rented homes near Carpenders Park station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Leave it or put it right?
A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we’ll say so. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Frames and glazing around Eastbury
Historic houses like Headstone Manor (about 3.2 miles south-east) are a reminder that the area around Eastbury has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Eastbury is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as Eastbury Farm Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
DIY sealant or a professional job?
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. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
