- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes

Sand mastic in Aimes Green, done properly
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. Typical jobs include mastic dropping out of the joint and weathered mastic on the most exposed windows, on sash and case windows, brick reveals and tenement windows.
Homes in small places like Aimes Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Keep sills and gutters clear so water drains away
- Have rotten timber repaired before new mastic goes in
- Go gently near the mastic when preparing windows
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Aimes Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
