Sand mastic for homes and businesses in Dufftown
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include gaps between timber frames and stone or brick and weathered mastic on the most exposed windows, across timber door frames, sash and case windows and stone surrounds.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work is covered by our 12-month guarantee, wherever you are in Moray.

Aftercare tips
A little care helps the new joints last. Our advice:
- Inspect the joints round the windows every year or so
- Don’t paint over the new mastic
- Check with your local planning authority if your home is listed
- Make sure water runs off the sill
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
For landlords and businesses
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
How we quote for sand mastic
For a quick quote, just ask. The main things that affect it are:
- How easy the joints are to reach
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
Combining jobs into one visit normally makes better use of the time than several visits. We will give you a clear quote for the lot.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Roughly how big the job is
To get a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
Why it’s worth doing now in Dufftown
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Windows and doors in Dufftown
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against 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.

Signs you need sand mastic in Dufftown
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Signs it’s time to call us include:
- Old cement repairs round a window that have failed
- Gaps where the frame meets the masonry
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
If you live in an older home near St Mary of The Assumption, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Outdoor work around Dufftown depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- 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
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

Dufftown: your questions answered
What guarantee comes with sand mastic in Dufftown?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do sand mastic in Dufftown?
Yes, Dufftown is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How much does sand mastic cost in Dufftown?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
