About our glazing silicone in Wembley
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for leaks where conservatory glass meets the frame and silicone pulling away from the glass, on glass-to-frame joints, shower screens and conservatory frames.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Every job is covered by our one-year guarantee, wherever you are in Greater London.

The process
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours, depending on how many joints need doing, and we explain the cure time before we leave. In Wembley, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Mention if the joints have been sealed before
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

What we are called out for in Wembley
The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Keep an eye out for any of the following:
- Black or yellowed silicone on glass joints
- Silicone pulling away from the glass
- Leaks where conservatory glass meets the frame
- Cracked silicone between glass panels
If you let a flat or house near North Wembley station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Why act early in Wembley
You do not need new glazing because the sealant has gone. Sound glass and frames normally just need resealing, and we will tell you if that’s not the case. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

Windows and doors in Wembley
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, Wembley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Wembley Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Wembley
Can parking be tricky for a visit in Wembley?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you do glazing silicone in Wembley?
Yes. We work across London and the South East, and Wembley is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Are you insured?
Yes. We’re fully insured for every job we do.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
How long should I leave it?
It depends on the product. Before we leave, we will tell you the cure time.
What affects the cost of glazing silicone
The quote reflects the job in front of us. We look at:
- The product the joint needs
- How many areas need sealing
- Mould in or behind the old joints
- Working hours on commercial sites
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- Where the property is
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
How the job changes by surface
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We use a glazing silicone suited to each.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Landlords, agents and businesses in Wembley
We also work for property managers and facilities teams in Wembley and across Greater London. Several sites can be quoted together.
