Glazing silicone in Worcester Park
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. If you are dealing with shower screens leaking along the wall or tray and mouldy sealant around glass panels, we can put it right.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Worcester Park as anywhere.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Worcester Park homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Parish Church of St Mary the Virgin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. As a London address, Worcester Park can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like Cuddington Community Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Questions from Worcester Park
Can you help a landlord with a rental near Worcester Park station?
Yes, rental work is part of what we do. Just call 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 Worcester Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you reseal a frameless shower screen?
Yes. We remove the old silicone carefully, and the joints are cleaned and resealed.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you come to Worcester Park?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you offer different sealant colours?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Why it’s worth doing now in Worcester Park
Resealing cannot fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway, so you can call the right trade. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

How the job changes by surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. Failed sealant there lets water collect.
Conservatory frames
Leaks often start where the frame meets the wall. We remove the failed sealant and renew it.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A sealed unit that has misted inside
- Glass that needs replacing
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Inspect the sealant on glazing annually
- Keep harsh solvents off the silicone
- Stick to mild cleaners on glass
- Keep scrapers and blades away from the silicone
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
