Sand mastic in Laurieston, done properly
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with failed mastic on an exposed elevation and draughty sash windows at the surround, we can help, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
Aftercare is simple:
- Leave the new mastic unpainted
- Do not run silicone over sand mastic
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Questions from Laurieston
Is sand mastic in a coastal place like Laurieston any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I let a flat near Polmont station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
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 finished to sit neatly against the masonry.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How we quote for sand mastic
For a quick quote, just ask. What matters most is:
- Access and height
- The size of the job
- The product the joint needs
- How many areas need sealing
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Photos by email, if that’s easy
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, email us at info@mrmastic.co.uk.
How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a single window, longer for several, including the tidy-up. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
For landlords with property near Polmont station, any sash windows need sound mastic to keep draughts and rain out.

What sand mastic looks like in Laurieston
Laurieston is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you look after a building such as Graeme High School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Christ Church Episcopal Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
