Glazing Silicone in Brondesbury
Our applicators work in Brondesbury on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Sealant that was laid over old silicone and failed
- Leaks from the base of a shower screen
- Mouldy sealant around glass panels
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most jobs. In Brondesbury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

Glazing silicone for homes and businesses in Brondesbury
We work across Brondesbury on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job. If you have leaks from the base of a shower screen and leaks where conservatory glass meets the frame, we can help, on glass balustrade bases, glass-to-frame joints and rooflights alike.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Brondesbury.
A 12-month guarantee comes as standard.

What glazing silicone looks like in Brondesbury
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. Historic houses like Fenton House (about 1.5 miles north-east) are a reminder that the area around Brondesbury has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Christ Church, the joint between an old wall and a newer frame is generally the first place rain gets in. For site and facilities teams at buildings such as North West London Jewish Day School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Brondesbury station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Honest limits
New sealant cannot fix everything, and we will tell you before we start. It will not solve:
- Frames that have decayed or split
- Leaks from the roof covering or flashing (a roofer’s job)
- A roof that has moved or dropped
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.
Joints and surfaces we work on
- Glass-to-glass joints
- Conservatory frames
- Rooflights
- Glass-to-frame joints
- Shower screens
- Glass balustrade bases
Why deal with it now?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
Different surfaces, different methods
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
Common questions in Brondesbury
Is Brondesbury in your area for glazing silicone?
Yes. We work across London and the South East, and Brondesbury is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
I let a flat near Brondesbury station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for most jobs. We’ll tell you when we quote.
Do you replace glass?
That’s not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Quotes for glazing silicone in Brondesbury
For a quick quote, just ask. What matters most is:
- Whether the work is at height
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work and give you a clear price.
Looking after it afterwards
To keep the joints looking good and working properly:
- Get a new leak looked at quickly
- Avoid scraping close to the bead
- Ventilate the conservatory to cut condensation
- Wipe the screen down after showering
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.
