Sand mastic for homes and businesses in Ludgershall
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with wind and rain getting in round a sash window and silicone on a period window that looks wrong, we can put it right, whatever the surface.
Around Ludgershall, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Surface by surface
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Frames and glazing around Ludgershall
With historic houses such as Boarstall Tower (about 3.1 miles south-west) nearby, there’s older building stock in the area around Ludgershall as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Common problems we fix in Ludgershall
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Most people get in touch when they notice something like this:
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep sills and gutters clear so water drains away
- Do not run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
- Find out about consent before window work on a listed home
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Why act early in Ludgershall
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Ludgershall, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
