How we handle glazing silicone in Grange Park
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. Common call-outs are for water getting into a conservatory at the joints and glazing silicone that has cracked or come away, across glass balustrade bases, glass-to-glass joints and conservatory frames.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
All our work is covered by a 12-month guarantee.

Surface by surface
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Windows and doors in Grange Park
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Forty Hall (about 2 miles north-east) nearby, there’s older building stock in the area around Grange Park as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Grange Park station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you live in an older home near Church of St Mary Magdalene, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We trace the leak and confirm it’s a sealant joint.
- 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.
Before we arrive
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Avoid strong solvents on or near the sealant
- Clean glass with a mild cleaner and a soft cloth
- Keep scrapers and blades away from the silicone
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Grange Park questions
Can you help a landlord with a rental near Grange Park station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can parking be tricky for a visit in Grange Park?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully, and the joints are cleaned and resealed.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can you fix a leaking conservatory?
If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Do you seal glass balustrade bases?
We can, if the base joint is sealed. Send us pictures and we’ll take a look.
Can you replace a misted double-glazed unit?
That’s not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Common problems we fix in Grange Park
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly, the bead can peel away early.
It’s worth asking for a quote if you see:
- Cracked silicone between glass panels
- Leaking glazing joints on a rooflight
- Leaks where conservatory glass meets the frame
- Leaks from the base of a shower screen
