Glazing silicone in Coscote, done properly
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. We are often asked to deal with drips on the inside of a conservatory window and water getting into a conservatory at the joints, across rooflights, glass balustrade bases and glass-to-glass joints.
In a village or hamlet like Coscote, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours, depending on how many joints need doing, depending on the amount of work. Somewhere as small as Coscote, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Coscote: your questions answered
I let a flat near Didcot Parkway station. Can you help?

Is Coscote in your area for glazing silicone?
Yes, Coscote is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
How much does glazing silicone cost in Coscote?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
How long does the job take?
Most jobs take a few hours, depending on how many joints need doing, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you seal glass balustrade bases?
We can, if the base joint is sealed. Send us pictures and we will take a look.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
What sealant do you use on glazing?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
Do you reseal glass shower screens?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Use a gentle glass cleaner and a soft cloth
- Do not use a blade near the sealant
- Avoid strong solvents on or near the sealant
- Ventilate the conservatory to cut condensation
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
Surface by surface
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Glazing silicone in Coscote: local notes
With historic houses such as Brightwell Manor (about 4.1 miles east) nearby, there’s older building stock in the area around Coscote as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Andrew include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Didcot Parkway station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as Hagbourne Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Coscote
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that’s not the case. Older cottages and farmhouses around Coscote can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
