About our glazing silicone in Forestdale
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that’s often where the water gets in. Typical jobs include glass-to-glass joints that have split and shower screens leaking along the wall or tray, across rooflights, conservatory frames and glass-to-glass joints.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Forestdale.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Landlords, agents and businesses in Forestdale
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Honest limits
In fairness, some problems need a different trade:
- Leaks from the roof covering or flashing (a roofer’s job)
- A frame that needs repairing or replacing
- Condensation trapped between two panes
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Where we work in Forestdale
- Glass-to-frame joints
- Glass balustrade bases
- Conservatory frames
- Rooflights
- Shower screens
- Glass-to-glass joints
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Check the silicone on glass every year or so
- Run a squeegee over the glass when you are done
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
Common problems we fix in Forestdale
Shower screen silicone gets wet every day. Mould gets into it and the joint starts to lift.
People normally contact us when they notice something like this:
- Cracked silicone between glass panels
- Leaks from the base of a shower screen
- Leaks where conservatory glass meets the frame
- New silicone smeared over old sealant
If you look after a building such as Courtwood Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Forestdale
Do you cover Forestdale for glazing silicone?
Yes. We work across London and the South East, and Forestdale is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is parking an issue for glazing silicone in Forestdale?
Parking in Forestdale, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
How long does the job take?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Can you fix a leaking conservatory?
Often, if the leak is at a sealant joint. We find where the water gets in first before any sealing.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Can you replace a misted double-glazed unit?
That is not something we do. A misted unit has failed inside and needs replacing by a glazier.
Should I try DIY first?
You can, for simple jobs. 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.
What affects the cost of glazing silicone
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Access and height
- The type of sealant required
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
To help us quote quickly, please include:
- Roughly how big the job is
- The type of property
- What’s wrong with the joints now
- How we’d reach the joints
To get a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
What happens if it’s left?
If the problem is a misted unit or a broken panel, sealant won’t help. 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What glazing silicone looks like in Forestdale
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Historic houses like Addington Palace (about 0.9 miles north) are a reminder that the area around Forestdale has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
As a London address, Forestdale can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Sanderstead station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours, depending on how many joints need doing, and we explain the cure time before we leave.

- First, we check where the water gets in.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
