About our sand mastic in North End
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you have patchy fillers round a sash window and modern sealant on a period surround, we can help.
Somewhere as small as North End, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Every job comes with our 12-month guarantee.

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Whether work needs listed building consent
- Cracked or broken glass

What sand mastic looks like in North End
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.
For site and facilities teams at buildings such as The Flitch Green Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in North End
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like North End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What you get with us

- Quality sealants from Arbo and Everbuild
- Neat joints and a tidy finish
- Sanitary silicone with an anti-fungal additive in wet areas
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. Somewhere like North End needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Do you need sand mastic in North End?
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
It’s worth asking for a quote if you see:
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Crumbling sand mastic round a window
- Open joints round the window box
If you live in an older home near Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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.
