Glazing silicone for homes and businesses in Donnington
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We’re often asked to deal with black or yellowed silicone on glass joints and rooflight joints letting water in, on glass-to-frame joints, glass balustrade bases and rooflights.
In a village or hamlet like Donnington, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about glazing silicone in Donnington
Do you cover smaller places like Donnington?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do glazing silicone in Donnington?
Yes. Our work covers London and the South East, and Donnington is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is it possible to redo the silicone on a shower screen?
We can. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most jobs. For a village or hamlet like Donnington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.

What glazing silicone looks like in Donnington
With historic houses such as Shaw House (about 0.7 miles south-east) nearby, there’s older building stock in the area around Donnington 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Newbury station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as Shaw-cum-Donnington C.E. Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Honest limits
It helps to know what we can’t do:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Glass that needs replacing
- Water coming through the roof rather than a sealant joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on
- Rooflights
- Conservatory frames
- Glass-to-frame joints
- Glass-to-glass joints
- Shower screens
- Glass balustrade bases
How to look after the new joints
After the cure time, these simple habits help:
- Stick to mild cleaners on glass
- Inspect the sealant on glazing annually
- Keep harsh solvents off the silicone
- Clear the conservatory gutters regularly
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
Do you need glazing silicone in Donnington?
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that was laid over old silicone and failed
- Leaking glazing joints on a rooflight
- Conservatory leaks at frame and glazing joints
- Water tracking down the inner face of the glass
In the older streets around Parish Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
