About our glazing silicone in South Tottenham
Across South Tottenham, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you have silicone pulling away from the glass and water tracking down the inner face of the glass, we can put it right.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to most of a day, depending on the size of the job. 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.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

Questions from South Tottenham
Can parking be tricky for a visit in South Tottenham?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is South Tottenham in your area for glazing silicone?
Yes. Our work covers London and the South East, and South Tottenham is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
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 take it all out and start clean.
What does glazing silicone cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why act early in South Tottenham
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in South Tottenham, the repair is bigger than a sealant job.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What you get with us

What glazing silicone looks like in South Tottenham
Historic houses like Bruce Castle (about 1.1 miles north) are a reminder that the area around South Tottenham 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, South Tottenham can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like Earlsmead Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of Holy Trinity include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What the job involves on each surface
Glass-to-glass joints
You see these joints clearly, so a straight, even finish matters.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. We don’t install or replace glass.
What we can’t put right
To be straight with you, some problems need a different trade:
- A sagging or failing conservatory roof
- A frame that needs repairing or replacing
- A broken pane or roof panel
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Glass balustrade bases
- Shower screens
- Glass-to-frame joints
- Rooflights
- Conservatory frames
- Glass-to-glass joints
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep conservatory gutters clear of leaves
- Run a squeegee over the glass when you’re done
- Avoid scraping close to the bead
- Use gentle products around the joints
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
