Glazing silicone in Bedwell: local notes
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. Stevenage, which Bedwell is part of, is one of England’s post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
Schools such as Broom Barns Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Stevenage station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

How we handle glazing silicone in Bedwell
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. Common call-outs are for split or lifting silicone on glass and leaks where conservatory glass meets the frame, on glass-to-frame joints, glass balustrade bases and conservatory frames.
Around Bedwell, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

What else we do in Bedwell
Common problems we fix in Bedwell
Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.
Any of these means the joints need attention:
- Water tracking down the inner face of the glass
- Conservatory leaks at frame and glazing joints
- Sealant that was laid over old silicone and failed
- Glazing silicone that has cracked or come away
For an older house near a landmark such as Parish Church of St Andrew and St George, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How we quote for glazing silicone
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- The type of sealant required
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before we start.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Roughly how big the job is
- Pictures of the joints, sent by email
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
How to look after the new joints
So the new joints stay in good condition:
- Stick to mild cleaners on glass
- Avoid scraping close to the bead
- Open vents or windows to let moisture out
- Wipe the screen down after showering
Keep conservatory gutters clear so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with right away.
Your questions about glazing silicone in Bedwell
Should the sealant in an older Bedwell home be renewed?
Usually, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant won’t stick to old, so the old bead has to come out completely first.
Can you help a landlord with a rental near Stevenage station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you fit new glass or sealed units?
No. We renew the sealant. Glass and sealed units need a glazier.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it possible to redo the silicone on a shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Can a conservatory leak be sealed?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Why deal with it now?
If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly and point you to a glazier or roofer. In an older home around Bedwell, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many joints need doing. In a smaller place like Bedwell, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
