About our glazing silicone in Yiewsley
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 both get fresh anti-fungal silicone. Common call-outs are for leaking glazing joints on a rooflight and silicone pulling away from the glass, on shower screens, rooflights and glass-to-frame joints.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Yiewsley as anywhere.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many joints need doing and we leave things clean and tidy. In a London area like Yiewsley, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Yiewsley homes and the weather
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. London and the South East are among 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, Yiewsley can be tricky for parking: let us know about parking bays, permits or a driveway. Homes close to St Joseph the Worker & Dovetail Centre include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Southall station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Can I do it myself?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What the job involves on each surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glass balustrade bases
The base of a glass balustrade is normally sealed. Failed sealant there lets water collect.

What affects the cost of glazing silicone
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- The number and length of the joints
- The old material and how stubborn it is
- Whether there’s mould to deal with
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- Where the property is
- Whether it’s a home or a business
- Roughly how big the job is
Need a quote? Please phone 0345 464 0079 or drop us an email and tell us about the job. We’ll explain what we’d do and give you a clear quote before we start.
What happens if it’s left?
Resealing can’t fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway, so you can call the right trade. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Yiewsley, the repair is bigger than a sealant job.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
