Windows and doors in Hadley
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
If you let a flat or house near New Barnet station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Schools such as Susi Earnshaw Theatre School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Glazing silicone in Hadley
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. If you are dealing with glass-to-glass joints that have split and water running down inside the glass, we can help, on shower screens, glass-to-glass joints and glass-to-frame joints alike.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Hadley as anywhere.
A 12-month guarantee comes as standard.

What affects the cost of glazing silicone
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- The size of the job
- Working hours on commercial sites
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
What we need to know
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- The type of property
- How many joints, rooms or windows are involved

Surface by surface
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Shower screens
Mouldy or lifting sealant on a screen leaks. Cutting it out and resealing fixes it.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Clean glass with a mild cleaner and a soft cloth
- Keep air moving in the conservatory
- Squeegee the shower screen after each use
- Clear the conservatory gutters regularly
Don’t use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.

What else we do in Hadley
When to call us in Hadley
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.
Most people get in touch when they notice something like this:
- Leaks where conservatory glass meets the frame
- Leaks from the base of a shower screen
- New silicone smeared over old sealant
- Glass-to-glass joints that have split
In the older streets around Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Hadley
Do you work for landlords with property near New Barnet station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Hadley in your area for glazing silicone?
Yes. Our work covers London and the South East, and Hadley is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
How long will you be here?
As a guide, most jobs take 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 will tell you how long to expect.
Why deal with it now?
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we will tell you. In a flat in Hadley, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
