Glensburgh Sand Mastic
Our applicators work in Glensburgh on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Silicone on a period window that looks wrong
- Patchy fillers round a sash window
- Weathered mastic on the most exposed windows
Leave it or put it right?
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Around Glensburgh, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

About our sand mastic in Glensburgh
Traditional burnt sand mastic 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 tenement windows, timber door frames and sash and case windows, and common reasons people get in touch are silicone on a period window that looks wrong and cement or filler used on old window joints that has cracked.
In and around a place like Glensburgh, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows. For a place like Glensburgh, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

What sand mastic looks like in Glensburgh
Glensburgh is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
If you look after a building such as Graeme High School, the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
- Check with your local planning authority if your home is listed
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
What the job involves on each surface
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Questions from Glensburgh
Do you cover smaller places like Glensburgh?
Yes. Glensburgh is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect sand mastic in Glensburgh?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Falkirk.
Is the work guaranteed?
All our work has a 12-month guarantee.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
