Glazing silicone in Sarsden
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. If you have failed sealant around rooflight glass and water getting into a conservatory at the joints, we can help.
Somewhere as small as Sarsden, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work comes with a one-year guarantee, wherever you are in Oxfordshire.

Glazing silicone in Sarsden: local notes
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. With historic houses such as Chastleton House (about 4.3 miles north-west) nearby, there’s older building stock in the area around Sarsden as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Chipping Norton School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If it’s the roof itself, we’ll tell you. Where a wall is exposed, as many are in small places like Sarsden, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

How to look after the new joints
To keep the joints looking good and working properly:
- Stick to mild cleaners on glass
- Keep air moving in the conservatory
- Keep harsh solvents off the silicone
- Run a squeegee over the glass when you’re done
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Glass that needs replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Frames that have decayed or split
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

Sarsden: your questions answered
Will you come out to Sarsden?
Yes, Sarsden is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Sarsden in your area for glazing silicone?
Yes, Sarsden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you just put new silicone over the old?
A top-up rarely holds. The new bead can’t grip the old one, so we remove the old sealant and clean the joint.
What does glazing silicone cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where do you work from?
Mr Mastic is based in Crawley. We cover Sarsden and the rest of Oxfordshire.
How long does glazing silicone take?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When to call us in Sarsden
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Signs it’s time to call us include:
- Silicone pulling away from the glass
- New silicone smeared over old sealant
- Mouldy sealant around glass panels
- Water tracking down the inner face of the glass
Letting a property close to Kingham station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Questions to ask before booking
- When the joint can take water or movement
- Whether they seal over old material or remove it
- What guarantee comes with the work
- How much experience the applicator has

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most jobs and we leave things clean and tidy. For a village or hamlet like Sarsden, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
