Sand mastic for homes and businesses in Burnfoot
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have window mastic to renew ahead of painting and mastic worn away on windows facing the weather, we can put it right.
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 something isn’t right with it in that time, tell us and we will put it right.

What affects the cost of sand mastic
Every job gets its own quote. These are the things that affect it:
- Access and height
- How many areas need sealing
- The product the joint needs
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Can you work on commercial sites?

Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Can sand mastic be painted?

Work for landlords, hotels and businesses
Landlords and agents in Burnfoot can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Look over the window mastic once a year
- Make sure water runs off the sill
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several. Outside jobs in Burnfoot need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each window surround and the condition of the joint.
- 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
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Clear the area around the work

What sand mastic looks like in Burnfoot
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Schools such as Lesmahagow High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Carluke station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

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, which can matter on listed and conservation-area homes. In an older home around Burnfoot, damp from a failed joint can get into timber and plaster.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Do you need sand mastic in Burnfoot?
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
These are the problems we are asked about most:
- Gaps round a timber door in stone or brick
- Old cement repairs round a window that have failed
- Mastic worn away on windows facing the weather
- Old sand mastic that has cracked, crumbled or fallen out
In the older streets around Kirkmuirhill Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
