Glazing silicone in North End
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. If you are dealing with a quick top-up bead that didn’t last and silicone pulling away from the glass, we can help.
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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Windows and doors in North End
Historic houses like Heath House (about 0.3 miles south) are a reminder that the area around North End has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Alban the Martyr, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. North End is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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 fails, we can still redo it.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Use gentle products around the joints
- Keep conservatory gutters clear of leaves
- Check the silicone on glass every year or so
- Open vents or windows to let moisture out
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.

Look out for any of the following:
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
- Leaks from the base of a shower screen
- Glazing silicone that has cracked or come away
