About our sand mastic in Carstairs
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. Typical jobs include mastic dropping out of the joint and window mastic to renew ahead of painting, on period & listed homes, brick reveals and timber door frames.
Outdoor sealant needs a dry surface, so window work around Carstairs is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Make sure water runs off the sill
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- Mention any parking rules near the property

Related advice
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What guarantee comes with the work?
Every job comes with our one-year guarantee.
Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Carstairs, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

What sand mastic looks like in Carstairs
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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Rented homes near Carstairs station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Carstairs Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
