About our glazing silicone in Stoke Newington
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. If you have water tracking down the inner face of the glass and glass-to-glass joints that have split, we can help, whatever the surface.
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 Stoke Newington as anywhere.
All of our work is guaranteed for twelve months.

FAQs for Stoke Newington
Can parking be tricky for a visit in Stoke Newington?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you cover Stoke Newington for glazing silicone?
Yes, Stoke Newington is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Why not top up the existing silicone?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. Fitting glass is a separate trade.
Do you fit new glass or sealed units?
No. We renew the sealant. Glass and sealed units need a glazier.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Can landlords and businesses book you?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It won’t solve:
- Glass that needs replacing
- Water coming through the roof rather than a sealant joint
- A roof that has moved or dropped
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Frames and glazing around Stoke Newington
Historic houses like Sutton House (about 1.7 miles south-east) are a reminder that the area around Stoke Newington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Homes close to Old Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Stoke Newington station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Why it’s worth doing now in Stoke Newington
If the problem is a misted unit or a broken panel, sealant won’t help. We will tell you that rather than seal it anyway, so you can call the right trade. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Stoke Newington, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

How the job changes by surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
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.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most jobs. In Stoke Newington, 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 agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Before we arrive
- Keep children and pets away from the work area
- Mention any tricky access
- Move anything stored near the joints

Related advice
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Do not leave a drip for the next storm
- Keep conservatory gutters clear of leaves
- Ventilate the conservatory to cut condensation
- Use gentle products around the joints
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
When to call us in Stoke Newington
Shower screen silicone gets wet every day. Mould gets into it and the edges begin to peel.
The problems people normally mention when they call include:
- Water getting into a conservatory at the joints
- Shower screens leaking along the wall or tray
- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
For site and facilities teams at buildings such as St Mary's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
