- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
- Wind and rain getting in round a sash window
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Plan mastic work ahead of painting
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Sand mastic in A' Chrìon Làraich, done properly
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you have crumbling sand mastic round a window and gaps round a timber door in stone or brick, we can help.
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.
Big or small, it’s backed by our 12-month guarantee.

Different surfaces, different methods
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.

What else we do in A' Chrìon Làraich
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I add another job to the visit?

Why it’s worth doing now in A' Chrìon Làraich
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a place like A' Chrìon Làraich, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
