What the job involves on each surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. They’re resealed with a suitable sealant.
How we handle glazing silicone in Yiewsley
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint, and we reseal both. If you have stained, discoloured glazing silicone and silicone pulling away from the glass, we can help, whatever the surface.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs and we leave things clean and tidy. In Yiewsley, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Use a gentle glass cleaner and a soft cloth
- Check the gutters above the glazing for debris
- Run a squeegee over the glass when you are done
- Keep scrapers and blades away from the silicone
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.

What glazing silicone looks like in Yiewsley
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
As a London address, Yiewsley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near St Matthew's, the joint between an old wall and a newer frame is usually the first place rain gets in.

What affects the cost of glazing silicone
We do not publish a price list, because no two jobs are the same. What we look at:
- When we can work, for business premises
- Which sealant suits the joint
- The old material and how stubborn it is
- Whether there’s mould to deal with
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
How do I get a quote for glazing silicone in Yiewsley?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What guarantee do I get?
There’s a 12-month guarantee on every job.
Can you reseal a frameless shower screen?
We can. We remove the old silicone carefully before cleaning and resealing.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Why deal with it now?
A new conservatory roof is a big job. If the leak is a failed sealant joint renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Yiewsley, the repair is bigger than a sealant job.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
