About our sand mastic in Coatbridge
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We’re often asked to deal with gaps where the frame meets the masonry and weathered mastic on the most exposed windows, across tenement windows, brick reveals and timber door frames.
Scottish towns like Coatbridge tend to mix older stone-built streets, harled houses and newer estates, and windows range from older sash and case to modern uPVC. Each needs the right sealant against the right wall.
Big or small, you get the same 12-month guarantee in Coatbridge and across North Lanarkshire.

Sand mastic in Coatbridge: local notes
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you let a flat or house near Whifflet station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Mary's Rc Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as St. Ambrose High School, its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
- Keep sills and gutters clear so water drains away
- Check the mastic when you check the paintwork
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints for a typical job.

Do the sealants smell?

Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
