How we handle sand mastic in Orchard Leigh
We work across Orchard Leigh renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We’re often asked to deal with modern sealant on a period surround and weathered mastic on the most exposed windows, across sash and case windows, stone surrounds and tenement windows.
Around Orchard Leigh, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Windows and doors in Orchard Leigh
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Chenies Manor House (about 3.6 miles south-east) are a reminder that the area around Orchard Leigh has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Berkhamsted station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as St George's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Go gently near the mastic when preparing windows
- Clear gutters so water does not pour onto the windows
- Find out about consent before window work on a listed home
- Do not run silicone over sand mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

Advice
Common problems we fix in Orchard Leigh
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
The most common problems we see are:
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
For site and facilities teams at buildings such as Ley Hill School, its window and door frames need their mastic kept sound, just like a home’s.
