Ashendon Glazing Silicone
Glazing silicone for conservatories, rooflights, glass panels and shower screens for homeowners, landlords and businesses in Ashendon. Fully insured, ARBOMaster approved and guaranteed for a year.
- Water tracking down the inner face of the glass
- Leaking glazing joints on a rooflight
- Glazing silicone that has cracked or come away
Leave it or put it right?
Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Older cottages and farmhouses around Ashendon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is generally more efficient than separate visits. We will give you a clear price for the lot.
Why Ashendon customers choose us
- White, clear, grey or another colour, product permitting
- A sealant colour to suit the surroundings

- Domestic, commercial and hotel work

How we handle glazing silicone in Ashendon
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. We work on glass balustrade bases, shower screens and rooflights, and common reasons people get in touch are new silicone smeared over old sealant and water escaping where a screen meets the wall.
Mastic can only go onto a dry, clean joint, so window work in Ashendon is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Glass balustrade bases
The base of a glass balustrade is generally sealed. Failed sealant there lets water collect.
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. Somewhere like Ashendon needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive

What affects the cost of glazing silicone
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Which sealant suits the joint
- The number and length of the joints
- Whether old sealant or filler has to be cut out
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any previous sealing or DIY work
- The address or postcode of the job
- What’s wrong with the joints now
- Whether it’s a home or a business
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
We also work for property managers and facilities teams. We can quote a run of properties together.
Glazing silicone in Ashendon: local notes
With historic houses such as Waddesdon Manor (about 2.3 miles north-east) nearby, there’s older building stock in the area around Ashendon as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
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. For an older house near a landmark such as Parish Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Ashendon is about 5 miles north of Thame, in Buckinghamshire. Jobs in Ashendon get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee.

Local landmarks in Ashendon

DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
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.
