Sand mastic in Old Blair
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, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on brick reveals, tenement windows and stone surrounds, and common reasons people get in touch are old cement repairs round a window that have failed and gaps where the frame meets the masonry.
In and around a place like Old Blair, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

How the job changes by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

The process

It normally takes anything from a few hours to a full day, depending on how many windows. Around Old Blair, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
