Glazing & conservatory sealant in Highmoor, Oxfordshire

- Sealant that was laid over old silicone and failed
Glazing silicone in Highmoor, done properly
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on shower screens, glass balustrade bases and glass-to-frame joints, and the jobs we see most are leaking glazing joints on a rooflight and new silicone smeared over old sealant.
Around Highmoor, 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.
Big or small, you get the same one-year guarantee in Highmoor and across Oxfordshire.

Highmoor questions
Is Highmoor within the area you cover?
Yes. Highmoor is within the area we cover, which takes in towns, villages and rural addresses. 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 Highmoor?
Yes. We work across London and the South East, and Highmoor is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can you reseal a frameless shower screen?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.

What else we do in Highmoor
Should I try it myself first?
If you are 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.
A careful DIYer can reseal a simple joint, 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.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Highmoor needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Glazing silicone in Highmoor: local notes
Historic houses like Greys Court (about 2 miles south-east) are a reminder that the area around Highmoor 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Stoke Row Church of England School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Henley-On-Thames station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

How the job changes by surface
Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
Conservatory frames
Frame joints face sun and rain all year. Renewed sealant keeps water out.
Why act early in Highmoor
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Around Highmoor, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
