- Patchy fillers round a sash window
- Gaps where the frame meets the masonry
The process
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints in most cases. For a job in Bellshill, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.

Sand mastic for homes and businesses in Bellshill
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you’re dealing with weathered mastic on the most exposed windows and mastic that needs renewing before redecorating, we can put it right.
Wind and rain in a Scottish town like Bellshill find any gap around a frame. Frames on the side that takes the weather generally fail first.
All our work comes with a one-year guarantee, wherever you are in North Lanarkshire.

A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
When to call us in Bellshill

- Modern sealant on a period surround
Schools such as Cardinal Newman High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Why act early in Bellshill
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. If you live in a flat in Bellshill, failed sealant can send water to the neighbours below, and that is much harder to put right.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
