Sand mastic in Tottenham Hale, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on stone surrounds, sash and case windows and tenement windows, and common reasons people get in touch are mastic worn away on windows facing the weather and cement or filler used on old window joints that has cracked.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Tottenham Hale as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

Questions from Tottenham Hale
Is parking an issue for sand mastic in Tottenham Hale?
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.
I let a flat near Tottenham Hale station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
What does sand mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
How long does the job take?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll say how long yours will take.
Aftercare tips
A little care helps the new joints last. We recommend:
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
- Renew mastic before redecorating the windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Tottenham Hale.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

Frames and glazing around Tottenham Hale
With historic houses such as Bruce Castle (about 1 mile north-west) nearby, there’s older building stock in the area around Tottenham Hale as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
For site and facilities teams at buildings such as Ferry Lane Primary School, its window and door frames need their mastic kept sound, just like a home’s. As a London address, Tottenham Hale can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
