Glazing silicone for homes and businesses in Chenies
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on glass balustrade bases, glass-to-frame joints and shower screens, and common reasons people get in touch are black or yellowed silicone on glass joints and a quick top-up bead that didn’t last.
Somewhere as small as Chenies, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same one-year guarantee.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why act early in Chenies
If the problem is a misted unit or a broken panel, sealant won’t help. We will tell you that rather than seal it anyway and point you to a glazier or roofer. In a small place like Chenies, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Chenies questions
Is Chenies within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Chalfont & Latimer station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Do you replace glass?
We don’t replace glass. We reseal the joints around it, and we will tell you if a unit looks like it has failed.
Can you reseal the base of a glass balustrade?
We can. We cut out the failed sealant and reseal the base joint using a sealant that suits the materials.
Will resealing stop my conservatory leaking?
If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we will tell you.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
Chenies homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Chenies Manor House (about 0.2 miles south) are a reminder that the area around Chenies 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 an older house near a landmark such as Church of St Michael, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Chalfont & Latimer station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Chenies School, the mastic around its windows and doors needs looking after like any other building’s.
