Sand mastic in Langlee
We work across Langlee renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. Typical jobs include modern sealant on a period surround and mastic that needs renewing before redecorating, across tenement windows, sash and case windows and timber door frames.
In and around a place like Langlee, 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
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, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Advice
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or will not open
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal
- Timber door frames
- Stone surrounds
- Tenement windows
- Brick reveals
- Sash and case windows
- Period & listed homes
What the job involves on each surface
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.

It takes a while. It skins first and hardens fully later, and we will tell you what to expect.

Yes. We are fully insured.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new sealant bonds properly.

Are you an approved applicator?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What sand mastic looks like in Langlee
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Peel House (about 4.8 miles west) nearby, there’s older building stock in the area around Langlee 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 is traditional sand mastic.
Managing a site like Galashiels Academy? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Tweedbank station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
