Glazing silicone for homes and businesses in Arnos Grove
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. If you are dealing with water running down inside the glass and sealant that was laid over old silicone and failed, we can put it right, whatever the surface.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What happens if it’s left?
You do not need new glazing because the sealant has gone. Sound glass and frames normally just need resealing. 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. Dealing with it early is far simpler.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Glazing silicone in Arnos Grove: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. With historic houses such as Bruce Castle (about 2.6 miles south-east) nearby, there’s older building stock in the area around Arnos Grove as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Bowes Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near New Southgate station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Can you do glazing silicone in Arnos Grove?
Yes, Arnos Grove is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
How long does glazing silicone take?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job, including the preparation. We will confirm how long when we quote.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you just put new silicone over the old?
It does not last. The new bead cannot grip the old one so we take it all out and start clean.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. In a London area like Arnos Grove, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

Related advice
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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 does not work out, we can still put it right.
Do you need glazing silicone in Arnos Grove?
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
Signs it’s time to call us include:
- Water getting into a conservatory at the joints
- Glass-to-glass joints that have split
- Water tracking down the inner face of the glass
- Silicone pulling away from the glass
In the older streets around Syro-Malabar Catholic Church of London, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- What the cure time is
