How we handle sand mastic in Aith
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you have gaps round a timber door in stone or brick and silicone on a period window that looks wrong, we can put it right.
Outdoor sealant needs a dry surface, so window work around Aith is planned around the weather. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

FAQs for Aith
Is Aith within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Is sand mastic in a coastal place like Aith any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
How do I get a quote for sand mastic in Aith?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
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 per window, depending on the condition of the joints. Outside jobs in Aith need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Let us know about earlier repairs to the joints

Advice
Sand mastic in Aith: local notes
Aith is within about 1 mile 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 failed outside joints work against that.
Around Aith, as everywhere, sand mastic is only as good as the preparation behind it.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens if it’s left?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Common problems we fix in Aith
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
The most common problems we see are:
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window
- Open joints round the window box
Homes close to Aith Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
