How we handle sand mastic in Hill Grove
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with crumbling sand mastic round a window and old cement repairs round a window that have failed, across tenement windows, stone surrounds and brick reveals.
Somewhere as small as Hill Grove, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.

Hill Grove homes and the weather
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.
Managing a site like Swanmore Church of England Aided Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Botley station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

When to call us in Hill Grove
Some old mastic was never deep enough. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
These are the problems we’re asked about most:
- Silicone on a period window that looks wrong
- Window mastic to renew ahead of painting
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
In the older streets around Church of St Barnabas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
