About our glazing silicone in Coombe
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it, and if it’s something sealant cannot fix, we will tell you. Common call-outs are for glazing silicone that has cracked or come away and conservatory leaks at frame and glazing joints, across glass-to-frame joints, glass-to-glass joints and shower screens.
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, letting in draughts and water.
We stand behind the work with a 12-month guarantee.

Glazing silicone in Coombe: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Schools such as Coombe Wood School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Coombe is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours, depending on how many joints need doing. In Coombe, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

Your questions about glazing silicone in Coombe
I let a flat near South Croydon station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is parking a problem for a job in Coombe?
Parking in Coombe, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you fit new glass or sealed units?
No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours, depending on how many joints need doing. We’ll tell you when we quote.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep harsh solvents off the silicone
- Wipe the screen down after showering
- Do not use a blade near the sealant
- Open vents or windows to let moisture out
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
When to call us in Coombe
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
The most common problems we see are:
- Failed joints on frameless glass
- Split or lifting silicone on glass
- Conservatory leaks at frame and glazing joints
- Water tracking down the inner face of the glass
If you let a flat or house near South Croydon station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why act early in Coombe
Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame so we choose a glazing silicone instead. 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 the work is at height. Your quote takes all of that into account.
