How we handle sand mastic in Dedridge
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 have old cement repairs round a window that have failed and mastic dropping out of the joint, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

How the job changes by surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is usually favoured.
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Common problems we fix in Dedridge
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
People usually contact us when they notice one of these:
- Draughty sash windows at the surround
- Modern sealant on a period surround
- Failed mastic on an exposed elevation
- Cracked mastic round a front door frame
If you live in an older home near Livingston Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Windows and doors in Dedridge
Historic houses like Howden House (about 0.9 miles north) are a reminder that the area around Dedridge has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Letting a property close to Livingston South station? Then any sash windows need sound mastic to keep draughts and rain out. Schools such as St. Margaret's Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

- Cracked or broken glass

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Why act early in Dedridge
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- Access and height
