Glazing silicone in Lower Green, done properly
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it and tell you plainly if the cause is something else. If you are dealing with new silicone smeared over old sealant and glazing silicone that has cracked or come away, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Lower Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Rotten or badly damaged frames
- Glass that needs replacing
- Water coming through the roof rather than a sealant joint

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

What glazing silicone looks like in Lower Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Stargroves (about 4.1 miles south-east) are a reminder that the area around Lower Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Kintbury station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Homes close to Church of St Michael include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Inkpen Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How the job changes by surface
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Looking after it afterwards
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Avoid scraping close to the bead
- Clear the conservatory gutters regularly
- Squeegee the shower screen after each use
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
Why it’s worth doing now in Lower Green
Topping up old silicone can look like a fix, but new silicone will not bond to old, and the leak normally returns. A proper reseal is the lasting answer. In a small place like Lower Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why choose Mr Mastic in Lower Green
