Why act early in Steeple Aston
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Steeple Aston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Sand mastic in Steeple Aston
We work across Steeple Aston renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, sash and case windows and timber door frames, and the jobs we see most are mastic dropping out of the joint and draughts and rain around sash boxes.
In a village or hamlet like Steeple Aston, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in Steeple Aston as everywhere else we work.

Aftercare tips
To keep the joints looking good and working properly:
- Keep modern sealant off the mastic
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
