When to call us in Glenboig
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Failed seals between different materials
Rented homes near Gartcosh station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic for homes and businesses in Glenboig
On houses, flats and commercial buildings across Glenboig, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on copings & trims, concrete & block and render & cladding joints, and common reasons people get in touch are weathered mastic that no longer stretches and sealant pulling away from one side of the joint.
In and around a place like Glenboig, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Render that’s blown, hollow or coming away
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Brickwork movement joints
- Façade panels
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
Glenboig buildings and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Glenboig is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
If you look after a building such as Buchanan High School, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church Of Scotland, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What you get with us
- Experience in homes, commercial sites and hotels
- 20+ years of sealant experience
- Anti-fungal sanitary silicone in wet areas
- Old sealant always removed completely
