- Leaks from the base of a shower screen
Glazing silicone for homes and businesses in Cockpole Green
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. Typical jobs include mouldy sealant around glass panels and leaking glazing joints on a rooflight, across glass-to-glass joints, conservatory frames and shower screens.
Mastic can only go onto a dry, clean joint, so window work in Cockpole Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same 12-month guarantee in Cockpole Green and across Wokingham.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most jobs. Somewhere as small as Cockpole Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

Common problems we fix in Cockpole Green
UV light ages silicone and roof joints get the most sun. Old silicone hardens, cracks and loses its grip to the glass and frame.
Any of these means the joints need attention:
- Sealant that was laid over old silicone and failed
- Shower screens leaking along the wall or tray
- Failed sealant around rooflight glass
- Glass-to-glass joints that have split
If you look after a building such as Crazies Hill CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Cockpole Green: your questions answered
I let a flat near Shiplake station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Is Cockpole Green within the area you cover?
Yes. Cockpole Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is balustrade sealant something you do?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Cockpole Green and the rest of Wokingham, along with the rest of our area.
Can I do it myself?
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.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Act on drips or damp patches early
- Keep scrapers and blades away from the silicone
- Check the gutters above the glazing for debris
- Check the silicone on glass every year or so
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.

What glazing silicone looks like in Cockpole Green
Historic houses like Harleyford Manor (about 2.7 miles north-east) are a reminder that the area around Cockpole 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. London and the South East are among 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 St Paul's Mission Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Shiplake station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
