Glazing & conservatory sealant in North Woolwich, Greater London
Glazing joints in North Woolwich need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Glass-to-glass joints that have split
- New silicone smeared over old sealant
- Water getting into a conservatory at the joints
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we handle glazing silicone in North Woolwich
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. We work on shower screens, glass-to-glass joints and glass balustrade bases, and common reasons people get in touch are shower screens leaking along the wall or tray and water tracking down the inner face of the glass.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most jobs. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in North Woolwich. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Squeegee the shower screen after each use
- Use a gentle glass cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
- Inspect the sealant on glazing annually
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below long before you see it.
What we are called out for in North Woolwich
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
Common reasons people contact us are:
- Failed joints on frameless glass
- Drips on the inside of a conservatory window
- Leaking glazing joints on a rooflight
- Stained, discoloured glazing silicone
If you let a flat or house near Woolwich Dockyard station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Frames and glazing around North Woolwich
Historic houses like Eastbury Manor House (about 2.9 miles north-east) are a reminder that the area around North Woolwich has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
North Woolwich is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as Oasis Academy Silvertown, the mastic around its windows and doors needs looking after like any other building’s.

Your questions about glazing silicone in North Woolwich
Is parking a problem for a job in North Woolwich?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is North Woolwich in your area for glazing silicone?
Yes, North Woolwich is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
What information do you need?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Do you fit new glass or sealed units?
That’s not something we do. A misted unit has failed inside, and a glazier needs to replace it.
