Questions from Greenlees
Is Greenlees in your area for sand mastic?
Yes. We work across all of Scotland, and Greenlees is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is Greenlees within the area you cover?
Yes, Greenlees is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once.
Sand mastic for homes and businesses in Greenlees
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We work on sash and case windows, brick reveals and stone surrounds, and common reasons people get in touch are draughty sash windows at the surround and cement or filler used on old window joints that has cracked.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
- Check with your local planning authority if your home is listed
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Greenlees homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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.
Letting a property close to Kirkhill station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as West Coats Primary School, the mastic around its windows and doors needs looking after like any other building’s.

When to call us in Greenlees
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Common reasons people contact us include:
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
For an older house near a landmark such as Cambuslang Baptist Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Greenlees, 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 is generally more efficient than separate visits. You will get one clear quote for the whole job.
