Auchenheath Sand Mastic
We cover Auchenheath for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- A silicone bead on a sash window that spoils the look
- Open joints round the window box
- Gaps round a timber door in stone or brick
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours per window, depending on the condition of the joints. For a place like Auchenheath, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

How we handle sand mastic in Auchenheath
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on timber door frames, period & listed homes and tenement windows, and the jobs we see most are mastic dropping out of the joint and mastic worn away on windows facing the weather.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. 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 few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Questions from Auchenheath
Do you cover smaller places like Auchenheath?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Carluke station. Can you help?
Yes. We work for landlords and agents as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later, and we will tell you what to expect.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
When to call us in Auchenheath
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
The problems people usually mention when they call include:
- A silicone bead on a sash window that spoils the look
- Gaps between timber frames and stone or brick
- Weathered mastic on the most exposed windows
- Old sand mastic that has cracked, crumbled or fallen out
If you let a flat or house near Carluke station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What else we do in Auchenheath
Surface by surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Clear gutters so water doesn’t pour onto the windows
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Do not run silicone over sand mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Auchenheath homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Homes close to Kirkmuirhill Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Lesmahagow High School, larger buildings have plenty of frames, and the mastic around each one ages.
