About our sand mastic in New Monkland
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you have draughts and rain around sash boxes and silicone on a period window that looks wrong, we can put it right.
Mastic can only go onto a dry joint, so outside work in New Monkland depends on the weather. Let us know about access to every frame, including any upstairs.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
Looking after new joints is easy:
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
For landlords and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
New Monkland homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Airdrie station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Airdrie Academy, the mastic around its windows and doors needs looking after like any other building’s.

What affects the quote in New Monkland
Your quote is based on your job. We take into account:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- The product the joint needs
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- What’s wrong with the joints now
- Roughly how big the job is
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.
Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Do you cover New Monkland for sand mastic?
Yes. Our work covers the whole of Scotland, and New Monkland is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.

What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
How long will you be here?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
