About our window mastic in Tottenham Green
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with whistling draughts around closed windows and a bead that doesn’t match the frame, we can help, on window sills, composite doors and timber windows & doors alike.
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 Tottenham Green as anywhere.
Each job carries a 12-month guarantee.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. In Tottenham Green, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Mention if the joints have been sealed before
How to get a quote
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll take it from there.

Common problems we fix in Tottenham Green
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
The most common problems we see are:
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
- Leaking joints at the ends of sills
Managing a site like Earlsmead Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How we quote for window mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- The number and length of the joints
- How easy the joints are to reach
- Working hours on commercial sites
- Which sealant suits the joint
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Photos by email, if that’s easy
If you’re in Tottenham Green and need window mastic, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
Windows and doors in Tottenham Green
With historic houses such as Bruce Castle (about 0.9 miles north) nearby, there’s older building stock in the area around Tottenham Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Tottenham Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near Church of Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp problems in the wall away from the window
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
What we seal
- Window sills
- uPVC windows

Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a flat in Tottenham Green, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Tottenham Green: your questions answered
Is parking a problem for a job in Tottenham Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you cover Tottenham Green for window mastic?
Yes. We work across London and the South East, and Tottenham Green is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
