Sand mastic for homes and businesses in Auchenreoch
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include mastic dropping out of the joint and weathered mastic on the most exposed windows, across stone surrounds, sash and case windows and timber door frames.
In and around a place like Auchenreoch, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY sealant or a professional job?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Damaged stone surrounds
- Whether work needs listed building consent
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
What we seal
- Tenement windows

What else we do in Auchenreoch
Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Auchenreoch homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Rented homes near Lenzie station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Kirkintilloch High School? Then the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
- Make sure water runs off the sill
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
