How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. Outdoor work around Cumnock depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in

How we handle sand mastic in Cumnock
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. Typical jobs include mastic dropping out of the joint and wind and rain getting in round a sash window, across sash and case windows, timber door frames and brick reveals.
In and around a place like Cumnock, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
All of our work is guaranteed for twelve months, in Cumnock and everywhere else we cover.

What sand mastic looks like in Cumnock
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. Historic houses like Dumfries House (about 1.9 miles west) are a reminder that the area around Cumnock has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Crichton Church of Scotland, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Robert Burns Academy, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Your questions about sand mastic in Cumnock
Do you work for landlords with property near Auchinleck station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is Cumnock in your area for sand mastic?
Yes. We work across all of Scotland, and Cumnock is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Should I use sand mastic or silicone?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic can sit properly.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Why it’s worth doing now in Cumnock
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. 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. You’ll have a clear quote before any work starts.
