What we do, step by step
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing in most cases. In Collier Row, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Getting ready for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Glazing silicone in Collier Row
A frameless shower screen depends on its silicone. Leaks usually come from the wall joint or the tray joint, and we reseal both. If you have drips on the inside of a conservatory window and leaks where conservatory glass meets the frame, we can help, on conservatory frames, rooflights and glass-to-glass joints alike.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
If you do try it yourself, take your time over the 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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Frames that have decayed or split
- Leaks from the roof covering or flashing (a roofer’s job)
- Glass that needs replacing
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- Glass-to-glass joints
- Conservatory frames
- Shower screens
- Rooflights

Signs you need glazing silicone in Collier Row
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Common reasons people contact us include:
- New silicone smeared over old sealant
- Drips on the inside of a conservatory window
- Leaking glazing joints on a rooflight
- Split or lifting silicone on glass
Hare Hall, about 1.7 miles east, is one of the historic houses in the wider area around Collier Row.
What your quote should include
- Who does the work, and how experienced they are
- Are they insured?
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
Why act early in Collier Row
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames usually just need resealing, and we’ll tell you if that is not the case. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Collier Row, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

What glazing silicone looks like in Collier Row
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Rise Park Infant School, larger buildings have plenty of frames, and the mastic around each one ages. As a London address, Collier Row can be tricky for parking: let us know about parking bays, permits or a driveway.

Common questions in Collier Row
Can you help a landlord with a rental near Romford station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Can parking be tricky for a visit in Collier Row?
Parking in Collier Row, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you fix a leaking conservatory?
If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we will say so.
Do you replace glass?
That is not something we do. A misted unit has failed inside and needs replacing by a glazier.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Clear the conservatory gutters regularly
- Squeegee the shower screen after each use
- Keep air moving in the conservatory
- Keep harsh solvents off the silicone
Do not use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.
For landlords and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.
