How we handle sand mastic in Newbigging
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Typical jobs include draughty sash windows at the surround and silicone on a period window that looks wrong, across period & listed homes, stone surrounds and sash and case windows.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Big or small, you get the same one-year guarantee.

Common problems we fix in Newbigging
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Keep an eye out for these signs:
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
- Mastic round period door frames that has failed
- Open joints round the window box

Newbigging: your questions answered
Do you cover smaller places like Newbigging?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Carstairs station?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Surface by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What sand mastic looks like in Newbigging
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
