About our sand mastic in Calderbank
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on timber door frames, period & listed homes and stone surrounds, and the jobs we see most are failed mastic on an exposed elevation and gaps round a timber door in stone or brick.
Outdoor sealant needs a dry surface, so window work around Calderbank is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. Outdoor work around Calderbank depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know if you’ve seen damp or leaks

Advice
Calderbank homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against 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.
Letting a property close to Airdrie station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Brannock High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Calderbank is about 2 miles south of Airdrie, in North Lanarkshire. Anywhere in ML6, our applicators can take on sand mastic. Our North Lanarkshire coverage runs to 89 places, Calderbank among them. Our Glasgow page covers work nearby.
We work across ML6 for sand mastic and the streets around it. If you need sand mastic at a property on Main Street, Crow-Wood Road and Crowwood Crescent or a nearby road, our applicators can take on the job. Other places close to Calderbank include Chapelhall (1 mile east), Gartness (1 mile north-east), Airdrie (2 miles north), Holytown (2 miles south) and Moffat Mills (2 miles north-east).

What’s near Calderbank

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Do you cover Calderbank for sand mastic?
Yes. We work across all of Scotland, and Calderbank is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.

Common problems we fix in Calderbank
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The problems people generally mention when they call are:
- Draughts and rain around sash boxes
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
Homes close to Calderbank Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
