About our sand mastic in Craigmarloch
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. If you’re dealing with window mastic to renew ahead of painting and cracked mastic round a front door frame, we can help, on brick reveals, timber door frames and stone surrounds alike.
In and around a place like Craigmarloch, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
All our work is covered by our one-year guarantee, wherever you are in North Lanarkshire.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Clear gutters so water does not pour onto the windows
- Get any rot dealt with first
- Do not paint over the new mastic
- Find out about consent before window work on a listed home
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
What sand mastic looks like in Craigmarloch
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
If you look after a building such as Our Lady's High, the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
