DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Glazing silicone for homes and businesses in Roe Green
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. We work on glass balustrade bases, glass-to-glass joints and glass-to-frame joints, and common reasons people get in touch are sealant that was laid over old silicone and failed and drips on the inside of a conservatory window.
Around Roe Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What does glazing silicone cost?

Which silicone is used for glass joints?
We use a neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
Why act early in Roe Green
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Where a wall is exposed, as many are in small places like Roe Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Avoid scraping close to the bead
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
- Keep air moving in the conservatory
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Surface by surface
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
What glazing silicone looks like in Roe Green
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.
If you look after a building such as Sandon Junior Mixed and Infant School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Ashwell & Morden station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
