Sand mastic in Cartland: local notes
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.
For site and facilities teams at buildings such as Lanark Grammar School, larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic in Cartland, done properly
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We work on tenement windows, timber door frames and stone surrounds, and people most often call us about old cement repairs round a window that have failed and modern sealant on a period surround.
In and around a place like Cartland, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. Somewhere like Cartland may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

Advice
FAQs for Cartland
Will you come out to Cartland?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Lanark station. Can you help?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new sealant go over the old?
No, and we never do. 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.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick normally suit sand mastic and newer frames usually get a flexible sealant.

Why it’s worth doing now in Cartland
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. 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.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Signs you need sand mastic in Cartland
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
The problems people normally mention when they call are:
- Gaps round a timber door in stone or brick
- Old sand mastic that has cracked, crumbled or fallen out
- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
For landlords with property near Lanark station, older sash windows in a rental need their mastic kept sound to keep the weather out.
