About our sand mastic in Netherton
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you are dealing with silicone on a period window that looks wrong and mastic dropping out of the joint, we can help.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Netherton, and in a tenement the outside of the building may be a shared repair.
There’s a 12-month guarantee on every job.

Sand mastic in Netherton: 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Knightswood Secondary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Knightswood St Margaret's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Broken panes
- Sashes that rattle, stick or won’t open
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Where we work in Netherton

Why it’s worth doing now in Netherton
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. For landlords in Netherton, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.

Related advice
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Keep an eye out for these signs:
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
