Glazing silicone in Great Haseley, done properly
Glass replacement isn’t something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. We work on glass-to-frame joints, glass balustrade bases and conservatory frames, and common reasons people get in touch are a quick top-up bead that didn’t last and silicone pulling away from the glass.
Outdoor sealant needs dry, clean surfaces, so work on frames around Great Haseley is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same 12-month guarantee in Great Haseley and across Oxfordshire.

Why act early in Great Haseley
You don’t need new glazing because the sealant has gone. Sound glass and frames usually just need resealing, and we’ll tell you if that’s not the case. In a small place like Great Haseley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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 will explain what it covers.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wipe the screen down after showering
- Ventilate the conservatory to cut condensation
- Get a new leak looked at quickly
- Avoid scraping close to the bead
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
What the job involves on each surface
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Rooflights
Water around a rooflight isn’t always the sealant. We check which it is.
What glazing silicone looks like in Great Haseley
With historic houses such as Garsington Manor (about 3.5 miles west) nearby, there’s older building stock in the area around Great Haseley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.

Do you fit new glass or sealed units?
No. A misted unit has failed inside and needs replacing by a glazier.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most jobs. In a small place like Great Haseley, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.

Common problems we fix in Great Haseley
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
If you can see any of these, it’s time to have the joints looked at:
- Water escaping where a screen meets the wall
- Leaking glazing joints on a rooflight
- Glazing silicone that has cracked or come away
- Water running down inside the glass
Managing a site like Great Milton Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
