Glazing silicone in West Hampstead
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We’re often asked to deal with mouldy sealant around glass panels and sealant that was laid over old silicone and failed, on conservatory frames, glass balustrade bases and glass-to-frame joints.
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, and access in West Hampstead is something to talk through when you book.
We stand behind the work with a one-year guarantee.

West Hampstead: your questions answered
Do you cover West Hampstead for glazing silicone?
Yes. Our work covers London and the South East, and West Hampstead is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Finchley Road & Frognal station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. Fresh silicone will not bond to cured silicone, so we remove the old sealant and clean the joint.
Do you replace glass?
No, our work is the silicone. Glass and sealed units need a glazier.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you insured?
Yes. We are fully insured.
DIY versus a professional finish
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Why act early in West Hampstead
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before you notice. 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

What we’re called out for in West Hampstead
Using a sealant not made for glass causes many failures. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Keep an eye out for these signs:
- Drips on the inside of a conservatory window
- New silicone smeared over old sealant
- Glass-to-glass joints that have split
- Glazing silicone that has cracked or come away
If you look after a building such as Emmanuel Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In West Hampstead, 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.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Before we arrive
- Let us know about parking restrictions
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Advice
What the job involves on each surface
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Frames and glazing around West Hampstead
With historic houses such as Fenton House (about 0.5 miles north-east) nearby, there’s older building stock in the area around West Hampstead as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Finchley Road & Frognal station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. As a London address, West Hampstead can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not use a blade near the sealant
- Keep air moving in the conservatory
- Squeegee the shower screen after each use
- Keep conservatory gutters clear of leaves
Clear the conservatory gutters regularly so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
