Sand mastic in Middle Wallop, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. Typical jobs include gaps where the frame meets the masonry and old cement repairs round a window that have failed, across sash and case windows, stone surrounds and period & listed homes.
In a village or hamlet like Middle Wallop, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, you get the same one-year guarantee.

Sand mastic in Middle Wallop: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Wallop Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Gaps round a timber door in stone or brick
- Old sand mastic that has cracked, crumbled or fallen out

- What insurance they hold
What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Where a wall is exposed, as many are in small places like Middle Wallop, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs 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 we start.

How to look after the new joints
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
- Clear gutters so water doesn’t pour onto the windows
- Sort the mastic before the decorators arrive
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
