Glazing silicone in Hampstead
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Common call-outs are for shower screens leaking along the wall or tray and black or yellowed silicone on glass joints, across conservatory frames, glass-to-glass joints and rooflights.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Hampstead is something to talk through when you book.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When to call us in 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:
- Water escaping where a screen meets the wall
- Drips on the inside of a conservatory window
- Cracked silicone between glass panels
- New silicone smeared over old sealant
Hampstead is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- Whether they seal over old material or remove it
- Whether you can choose the colour
- Who turns up on the day
- What insurance they hold
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A roof that has moved or dropped
- A sealed unit that has misted inside
- Failed flashing around a conservatory

If you manage several properties in or around Hampstead, several properties can go on one quote. Send us the addresses and the work at each.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
How the job changes by surface
Conservatory frames
Frame joints face sun and rain all year. A fresh bead seals them again.
Glass balustrade bases
The base of a glass balustrade is usually sealed. When it fails, water can sit in the channel.
The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Hampstead: your questions answered
Do you work for landlords with property near Finchley Road & Frognal station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Is Hampstead in your area for glazing silicone?
Yes. We work across London and the South East, and Hampstead is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can a conservatory leak be sealed?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
How long does the job take?
As a guide, most jobs take a few hours for most jobs. Bigger jobs take longer.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Why not top up the existing silicone?
New silicone will not bond to old silicone, so a top-up soon lets water through. The old bead always comes out first.
What does glazing silicone cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
What glazing silicone looks like in Hampstead
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Fenton House (about 0.4 miles north) are a reminder that the area around Hampstead has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Finchley Road & Frognal station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For an older house near a landmark such as St John-at-Hampstead church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
