How we handle glazing silicone in East Barnet
We work across East Barnet on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. We work on glass balustrade bases, shower screens and conservatory frames, and the jobs we see most are leaks where conservatory glass meets the frame and failed sealant around rooflight glass.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
All our work comes with a one-year guarantee, wherever you are in Greater London.

For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. In East Barnet, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
How to get a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
Related advice
Do you need glazing silicone in East Barnet?
Sunlight breaks sealant down, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.
It’s worth asking for a quote if you see:
- Cracked silicone between glass panels
- Leaks from the base of a shower screen
- Split or lifting silicone on glass
- Mouldy sealant around glass panels
East Barnet is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- How the colour is chosen
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
- How much experience the applicator has

Other services in East Barnet
Leave it or put it right?
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway, so you can call the right trade. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
Why us?
- You choose the colour before work begins
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- White, clear, grey or coloured to suit, where the product allows

Windows and doors in East Barnet
Historic houses like Heath Hall (about 4.2 miles south) are a reminder that the area around East Barnet 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 is traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
For landlords with property near Oakleigh Park station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to St Mary the Virgin include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

How the job changes by surface
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. It must be clean, neat and well bonded.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Don’t use a blade near the sealant
- Keep conservatory gutters clear of leaves
- Inspect the sealant on glazing annually
- Keep air moving in the conservatory
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
Your questions about glazing silicone in East Barnet
Is East Barnet in your area for glazing silicone?
Yes. Our work covers London and the South East, and East Barnet is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Is parking a problem for a job in East Barnet?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone and water gets between the layers. The old bead always comes out first.
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.
Can you replace a misted double-glazed unit?
Glass replacement is not our trade. We look after the sealant joints and can tell you if a unit seems to have gone.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before any work starts.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
