Smallburn homes and the weather
Smallburn is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Smallburn, as everywhere, sand mastic is only as good as the preparation behind it.

Sand mastic for homes and businesses in Smallburn
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We are often asked to deal with modern sealant on a period surround and crumbling sand mastic round a window, on brick reveals, tenement windows and timber door frames.
Mastic can only go onto a dry joint, so outside work in Smallburn depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
- Do not run silicone over sand mastic
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Questions from Smallburn
Is Smallburn within the area you cover?
Yes, Smallburn is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic in Smallburn guaranteed?
All our work, in Smallburn and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.
What we are called out for in Smallburn
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Common reasons people contact us include:
- Modern sealant on a period surround
- Gaps round a timber door in stone or brick
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
If you live in an older home near Muirkirk Old Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
