Windows and doors in Haverstock
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Keats House (about 0.8 miles north) nearby, there’s older building stock in the area around Haverstock as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like Fine Arts College? Then larger buildings have plenty of frames, and the mastic around each one ages. As a London address, Haverstock can be tricky for parking: let us know about parking bays, permits or a driveway.

How we handle glazing silicone in Haverstock
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. We work on glass balustrade bases, glass-to-glass joints and conservatory frames, and common reasons people get in touch are cracked silicone between glass panels and leaks from the base of a shower screen.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Haverstock is something to talk through when you book.
Every job is covered by our one-year guarantee.

What else we do in Haverstock
When to call us in Haverstock
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
People usually contact us after spotting one of these:
- Leaks where conservatory glass meets the frame
- Leaks from the base of a shower screen
- Drips on the inside of a conservatory window
- Rooflight joints letting water in
In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we quote for glazing silicone
Your quote is based on your job. We look at:
- When we can work, for business premises
- The size of the job
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.
Helping us quote
What to tell us when you ask for a quote:
- The rough size of the job
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The address or postcode of the job
If you’re in Haverstock and need glazing silicone, phone 0345 464 0079 or email us. Tell us what the problem is and where, and we’ll agree the price before any work begins.
How to look after the new joints
So the new joints stay in good condition:
- Check the silicone on glass every year or so
- Use gentle products around the joints
- Check the gutters above the glazing for debris
- Avoid scraping close to the bead
Don’t use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the problem grows.
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes a few hours for most jobs, depending on how much there is to do. In a London area like Haverstock, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Move anything stored near the joints

FAQs for Haverstock
I let a flat near South Hampstead station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Do you cover Haverstock for glazing silicone?
Yes, Haverstock is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you fit new glass or sealed units?
No. We renew the sealant. Glass and sealed units need a glazier.
Is it enough to run a bead over the old sealant?
Topping up is a common cause of leaks. We remove the old silicone, clean the joint and reseal.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How much does glazing silicone cost in Haverstock?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Leaks from the roof covering or flashing (a roofer’s job)
- A frame that needs repairing or replacing
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
