Glazing silicone for homes and businesses in Sedrup
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. Typical jobs include silicone pulling away from the glass and drips on the inside of a conservatory window, across rooflights, glass-to-glass joints and shower screens.
Homes in small places like Sedrup often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, whatever its size.

Sedrup: your questions answered
Is Sedrup within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Sedrup in your area for glazing silicone?
Yes, Sedrup is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Can a conservatory leak be sealed?
Often, if the leak is at a sealant joint. We trace the leak first, so you know what you are paying for.
Do you replace glass?
No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Are you insured?
Yes, we’re fully insured for every job we do.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does glazing silicone take?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We’ll give you a better idea when we quote.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
Sedrup homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Aylesbury station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you look after a building such as Stone Church of England Combined School, the mastic around its windows and doors needs looking after like any other building’s.

What we’re called out for in Sedrup
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
Look out for any of the following:
- Sealant that was laid over old silicone and failed
- Drips on the inside of a conservatory window
- Mouldy sealant around glass panels
- Split or lifting silicone on glass
For an older house near a landmark such as St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
- What happens if the job turns out different
- How much experience the applicator has
How we quote for glazing silicone
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- Whether the work is at height
- The number and length of the joints
- Working hours on commercial sites
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. We take all of that into account in your quote.
Asking for a quote
To help us quote quickly, let us know:
- Whether it has been sealed before
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
We don’t publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.
Why deal with it now?
A quick bead over the old sealant might stop a drip for a while, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Older cottages and farmhouses around Sedrup can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many joints need doing. Somewhere as small as Sedrup, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
How to prepare
- Mention any tricky access
- Keep children and pets away from the work area
- Mention any parking rules near the property
