How we handle sand mastic in Bakers Arms
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on brick reveals, stone surrounds and period & listed homes, and people most often call us about cracked mastic round a front door frame and crumbling sand mastic round a window.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Bakers Arms and across Greater London.

Bakers Arms homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Sutton House (about 2.5 miles south-west) are a reminder that the area around Bakers Arms has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Thomas Gamuel Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Stephen's, the joint between an old wall and a newer frame is generally the first place rain gets in.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check with your local planning authority if your home is listed
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Do you need sand mastic in Bakers Arms?
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they normally need raking out.
It’s worth asking for a quote if you see:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Patchy fillers round a sash window
If you let a flat or house near Leyton Midland Road station, older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- What happens if the job turns out different
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
What the job involves on each surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Why it’s worth doing now in Bakers Arms
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Bakers Arms, the repair is bigger than the sealant job would have been.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
