Surface by surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Glazing silicone for homes and businesses in Wexham Street
We do not replace glass, and misting between panes means a failed sealed unit. Our work is the sealant joints and that is often where the water gets in. We work on glass balustrade bases, shower screens and rooflights, and people most often call us about black or yellowed silicone on glass joints and failed joints on frameless glass.
In a village or hamlet like Wexham Street, 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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Landlords, agents and businesses in Wexham Street
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Water coming through the roof rather than a sealant joint
- Structural problems with a conservatory roof
- Frames that have decayed or split
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Glass balustrade bases
- Rooflights
- Glass-to-glass joints
- Conservatory frames
- Shower screens
- Glass-to-frame joints
Aftercare tips
So the new joints stay in good condition:
- Wipe the screen down after showering
- Keep harsh solvents off the silicone
- Ventilate the conservatory to cut condensation
- Act on drips or damp patches early
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.

Common problems we fix in Wexham Street
Some conservatory leaks are not sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
Signs it’s time to call us include:
- Stained, discoloured glazing silicone
- Drips on the inside of a conservatory window
- Silicone pulling away from the glass
- Leaks where conservatory glass meets the frame
Schools such as Khalsa Secondary Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- What product goes in the joint
- Whether they seal over old material or remove it
- How the colour is chosen
- Whether they’re fully insured

What glazing silicone looks like in Wexham Street
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Windsor Castle (about 4.3 miles south) nearby, there’s older building stock in the area around Wexham Street as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near St Andrew's Church Centre, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Slough station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
