Sand mastic in Drimlabarra
Across Drimlabarra, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. Common call-outs are for wind and rain getting in round a sash window and modern sealant on a period surround, on sash and case windows, period & listed homes and brick reveals.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In an older home around Drimlabarra, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

What we are called out for in Drimlabarra
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
These are the problems we’re asked about most:
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
- Mastic that needs renewing before redecorating
- Cracked mastic round a front door frame
For an older house near a landmark such as Church Of Scotland, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Don’t run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Check with your local planning authority if your home is listed
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

What else we do in Drimlabarra
Drimlabarra homes and the weather
Drimlabarra is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Drimlabarra is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Around Drimlabarra, as everywhere, sand mastic is only as good as the preparation behind it.
Drimlabarra is about 19 miles south-west of Saltcoats, in North Ayrshire. Across the KA27 area, we cover sand mastic for homes and businesses. Drimlabarra is one of 53 towns and villages in North Ayrshire we cover. Our Glasgow page covers work nearby, about 44 miles away.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
