About our glazing silicone in Midhurst
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We work on rooflights, glass-to-frame joints and glass balustrade bases, and people most often call us about leaking glazing joints on a rooflight and leaks where conservatory glass meets the frame.
Around Midhurst, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check the gutters above the glazing for debris
- Avoid scraping close to the bead
- Run a squeegee over the glass when you are done
- Open vents or windows to let moisture out
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we’ll find out which.
Why act early in Midhurst
A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Homes in smaller places like Midhurst can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

How the job changes by surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. It must be clean, neat and well bonded.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
What we are called out for in Midhurst
Glass and frames expand and contract with the temperature, and they do not move by the same amount. Over years, that movement tears the silicone.
Any of these means the joints need attention:
- Sealant that was laid over old silicone and failed
- Leaking glazing joints on a rooflight
- Cracked silicone between glass panels
- Shower screens leaking along the wall or tray
Managing a site like Midhurst CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Before you book anyone
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- What happens if the job turns out different
- Is the old sealant removed completely?
Midhurst homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Cowdray House (about 0.6 miles north-east) are a reminder that the area around Midhurst 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 Roman Catholic Church of Divine Motherhood, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Advice
Should I try it myself first?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
