About our sand mastic in Badshot Lea
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on timber door frames, stone surrounds and sash and case windows, and the jobs we see most are wind and rain getting in round a sash window and gaps where the frame meets the masonry.
Homes in small places like Badshot Lea often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Badshot Lea
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
These are the problems we’re asked about most:
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
In the older streets around St George's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Frames and glazing around Badshot Lea
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Farnham Castle (about 1.8 miles south-west) nearby, there’s older building stock in the area around Badshot Lea as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Badshot Lea Village Infant School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Aldershot station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Why it’s worth doing now in Badshot Lea
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Badshot Lea can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What else we do in Badshot Lea
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Check the mastic when you check the paintwork
- Clear gutters so water does not pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
