How the job changes by surface
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Rooflights
Water around a rooflight isn’t always the sealant. We check which it is.
Glazing silicone for homes and businesses in Stroud Green
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we will tell you. If you’re dealing with water escaping where a screen meets the wall and leaking glazing joints on a rooflight, we can help.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Stroud Green as anywhere.
Every job comes with our one-year guarantee, wherever you are in Greater London.

What glazing silicone looks like in Stroud Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
For landlords with property near Harringay station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Stroud Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Managing a site like St Aidan's Voluntary Controlled Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Common questions in Stroud Green
Can you help a landlord with a rental near Harringay station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can parking be tricky for a visit in Stroud Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Can you reseal a frameless shower screen?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you guarantee glazing sealant work?
Every job comes with our 12-month guarantee, and we are fully insured.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Why it’s worth doing now in Stroud Green
You do not need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that is not the case. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Stroud Green.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep air moving in the conservatory
- Do not leave a drip for the next storm
- Run a squeegee over the glass when you’re done
- Keep conservatory gutters clear of leaves
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
What we cannot put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- A sagging or failing conservatory roof
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Water coming through the roof rather than a sealant joint
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Rooflights
- Conservatory frames
- Glass balustrade bases

What affects the quote in Stroud Green
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- Working hours on commercial sites
- Whether there’s mould to deal with
- The old material and how stubborn it is
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
To make quoting easier, please include:
- The rough size of the job
- The problem you’ve noticed
- If someone has resealed it before
- Where the job is, and your postcode

How it works
We work through the job in order: 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 and we leave things clean and tidy. In Stroud Green, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on
- Let us know about parking restrictions
How to get a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
