Glazing silicone in Brightwell-cum-Sotwell, done properly
Many conservatory leaks come down to failed sealant 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.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Leaks from the roof covering or flashing (a roofer’s job)
- A frame that needs repairing or replacing
- A sealed unit that has misted inside
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Glass-to-frame joints
- Glass-to-glass joints
- Glass balustrade bases
- Conservatory frames
- Rooflights
- Shower screens
Leave it or put it right?
Replacing windows or a shower screen is not needed for a failed joint. 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. Where a wall is exposed, as many are in small places like Brightwell-cum-Sotwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Keeping the joints in good condition
So the new joints stay in good condition:
- Use gentle products around the joints
- Use a gentle glass cleaner and a soft cloth
- Squeegee the shower screen after each use
- Ventilate the conservatory to cut condensation
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we will find out which.

Advice
Your questions about glazing silicone in Brightwell-cum-Sotwell
Will you come out to Brightwell-cum-Sotwell?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Cholsey station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you fit new glass or sealed units?
That is not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Windows and doors in Brightwell-cum-Sotwell
Historic houses like Brightwell Manor (about 0.3 miles south-west) are a reminder that the area around Brightwell-cum-Sotwell has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Cholsey station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Brightwell-Cum-Sotwell Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
