Sand mastic in Crowmarsh Gifford, done properly
Across Crowmarsh Gifford, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We’re often asked to deal with draughty sash windows at the surround and modern sealant on a period surround, across timber door frames, period & listed homes and tenement windows.
Around Crowmarsh Gifford, 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.
All our work is covered by a one-year guarantee.

Sand mastic in Crowmarsh Gifford: local notes
With historic houses such as Brightwell Manor (about 2.7 miles west) nearby, there’s older building stock in the area around Crowmarsh Gifford as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Crowmarsh Gifford Church of England School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Cholsey station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St Mary Magdalene include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Different surfaces, different methods
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get any rot dealt with first
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like Crowmarsh Gifford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
