Glazing Silicone in Haddenham
Glazing joints in Haddenham need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- New silicone smeared over old sealant
- Water tracking down the inner face of the glass
- Rooflight joints letting water in
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep air moving in the conservatory
- Use a gentle glass cleaner and a soft cloth
- Use gentle products around the joints
- Run a squeegee over the glass when you are done
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
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.
Glazing silicone in Haddenham
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. Typical jobs include stained, discoloured glazing silicone and conservatory leaks at frame and glazing joints, on conservatory frames, rooflights and glass-to-frame joints.
Homes around Haddenham range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
All our work is covered by a 12-month guarantee, wherever you are in Buckinghamshire.

- Glass-to-frame joints
- Rooflights
- Glass-to-glass joints

Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.

Windows and doors in Haddenham
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Waddesdon Manor (about 4.9 miles north) are a reminder that the area around Haddenham has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Parish Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Haddenham & Thame Parkway station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive

Common problems we fix in Haddenham
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Common reasons people contact us include:
- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
- Leaks from the base of a shower screen
- Rooflight joints letting water in
Schools such as Haddenham Community Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Which colour the sealant will be
- What insurance they hold
- Whether all the old sealant comes out first
- How long the guarantee is
Why deal with it now?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Around Haddenham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Common questions in Haddenham
Is Haddenham within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Haddenham & Thame Parkway station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you seal glass balustrade bases?
Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.
Why not top up the existing silicone?
Silicone does not stick to silicone, so a top-up soon lets water through. The old bead always comes out first.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Should I try DIY first?
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.
