Specialist glazing silicone for Upper Heyford: careful preparation, the right product and tidy work. Ask us for a quick quote.
- New silicone smeared over old sealant
- Cracked silicone between glass panels
- Mouldy sealant around glass panels
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Run a squeegee over the glass when you’re done
- Clear the conservatory gutters regularly
- Act on drips or damp patches early
- Don’t use a blade near the sealant
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with right away.
Glazing silicone for homes and businesses in Upper Heyford
We work across Upper Heyford on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you have glass-to-glass joints that have split and water running down inside the glass, we can put it right, on glass-to-glass joints, glass-to-frame joints and rooflights alike.
In smaller places like Upper Heyford, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- A sagging or failing conservatory roof
- Water coming through the roof rather than a sealant joint
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Conservatory frames

Do you need glazing silicone in Upper Heyford?
Shower screen silicone gets wet every day. Mould gets into it and the joint starts to lift.
These are the problems we are asked about most:
- Silicone pulling away from the glass
- Water getting into a conservatory at the joints
- Failed joints on frameless glass
- Sealant that was laid over old silicone and failed
For an older house near a landmark such as Heyford Park Chapel, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Conservatory frames
Exposed frame joints wear with the weather. Renewed sealant keeps water out.
Why it’s worth doing now in Upper Heyford
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Homes in smaller places like Upper Heyford can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

Will the old sealant be removed?

That depends on the amount of work, but most jobs take 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.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on how many joints need doing. A visit to Upper Heyford is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
How to prepare

- Tell us if parking is tricky
