How we handle sand mastic in Earley
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 and built up by hand. On older homes, it suits the building far better than silicone. We are often asked to deal with failed mastic on an exposed elevation and mastic dropping out of the joint, across tenement windows, period & listed homes and brick reveals.
Walls in Earley that face the prevailing wind take the most weather, so the mastic there tends to fail first. It’s worth looking at every frame, not just the one that leaks.
Whatever the size of the job, you get the same one-year guarantee.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Common problems we fix in Earley
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
If you can see any of these, it’s time to have the joints looked at:
- Wind and rain getting in round a sash window
- Gaps round a timber door in stone or brick
- Mastic that needs renewing before redecorating
- Open joints round the window box
For site and facilities teams at buildings such as Radstock Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Earley
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In Earley, as anywhere, most leaks start as a small gap in a joint, and early is when they’re cheapest and quickest to sort.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
