Glazing & conservatory sealant in Norton Mandeville, Essex
Our applicators work in Norton Mandeville on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly.
- Failed joints on frameless glass
- Leaking glazing joints on a rooflight
- Split or lifting silicone on glass
When something else is needed
We will not take on work that will not last, so here’s what sealant can’t put right:
- Condensation trapped between two panes
- Water coming through the roof rather than a sealant joint
- Cracked or broken glass
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Shower screens
- Glass balustrade bases
- Rooflights
- Glass-to-glass joints
- Conservatory frames
- Glass-to-frame joints
Glazing silicone in Norton Mandeville, done properly
Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that’s often where the water gets in. We’re often asked to deal with leaks from the base of a shower screen and drips on the inside of a conservatory window, on glass-to-frame joints, glass balustrade bases and shower screens.
In a village or hamlet like Norton Mandeville, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Don’t leave a drip for the next storm
- Stick to mild cleaners on glass
- Run a squeegee over the glass when you are done
- Look over the glazing joints once a year
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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 does not work out, we can still put it right.
Leave it or put it right?
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Where a wall is exposed, as many are in small places like Norton Mandeville, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Common problems we fix in Norton Mandeville
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the joint starts to lift.
Any of these means the joints need attention:
- Mouldy sealant around glass panels
- Sealant that was laid over old silicone and failed
- Failed sealant around rooflight glass
- Water getting into a conservatory at the joints
For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for most jobs in most cases. Somewhere as small as Norton Mandeville, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Mention any tricky access
