How we handle sand mastic in Hairmyres
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and gaps where the frame meets the masonry, on timber door frames, brick reveals and sash and case windows.
In and around a place like Hairmyres, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
A one-year guarantee comes as standard.

What sand mastic looks like in Hairmyres
Hairmyres is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you let a flat or house near Hairmyres station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Leave it or put it right?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Around Hairmyres, water from a failed joint in an older stone home can soak into timber and plaster.
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 we need extra access for height. Your quote takes all of that into account.

What we are called out for in Hairmyres
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
If you look after a building such as Duncanrig Secondary School, larger buildings have plenty of frames, and the mastic around each one ages.

Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.

Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
