Sand mastic in Maltman's Hill
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on timber door frames, tenement windows and period & listed homes, and common reasons people get in touch are gaps between timber frames and stone or brick and weathered mastic on the most exposed windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Maltman's Hill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, in Maltman's Hill and everywhere else we cover.

How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
