Advice
Sand mastic in Armadale
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on sash and case windows, timber door frames and tenement windows, and common reasons people get in touch are draughts and rain around sash boxes and window mastic to renew ahead of painting.
In and around a place like Armadale, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.

How to look after the new joints
After the cure time, these simple habits help:
- Ask us before painting near the mastic
- Clear gutters so water does not pour onto the windows
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
What we can’t put right
New sealant can’t fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that rattle, stick or won’t open
- Masonry that needs repairing
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.

What sand mastic looks like in Armadale
Armadale is close to 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For landlords with property near Mallaig station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

FAQs for Armadale
Does living near the coast affect sand mastic in Armadale?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Armadale?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.
What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
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 beds in well.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Why it’s worth doing now in Armadale
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. 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.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
