Glazing silicone in Wealdstone, done properly
We do not replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. We work on glass-to-frame joints, rooflights and glass-to-glass joints, and people most often call us about glass-to-glass joints that have split and shower screens leaking along the wall or tray.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Wealdstone.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What glazing silicone looks like in Wealdstone
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. Historic houses like Headstone Manor (about 0.9 miles west) are a reminder that the area around Wealdstone has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you let a flat or house near Harrow & Wealdstone station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Wealdstone is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why it’s worth doing now in Wealdstone
Replacing windows or a shower screen isn’t needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that’s not the case. In a flat in Wealdstone, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

What we cannot put right
We will always be straight with you, so here’s what sealant can’t fix:
- Frames that have decayed or split
- Water coming through the roof rather than a sealant joint
- Cracked or broken glass
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Glass-to-frame joints
- Conservatory frames
- Shower screens
- Glass-to-glass joints
- Rooflights
- Glass balustrade bases
Do you need glazing silicone in Wealdstone?
Glass and frames expand and contract with the temperature, and they do not move by the same amount. In time, the sealant splits or pulls away.
The most common problems we see are:
- Sealant that was laid over old silicone and failed
- Leaks where conservatory glass meets the frame
- Failed joints on frameless glass
- Water running down inside the glass
Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Advice
Aftercare tips
Good habits help new joints last longer. A few tips:
- Squeegee the shower screen after each use
- Clear the conservatory gutters regularly
- Do not use a blade near the sealant
- Stick to mild cleaners on glass
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we will find out which.
