Why act early in Muirhead
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Around Muirhead, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

External mastic in Muirhead
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. Typical jobs include water getting into walls through failed joints and moss and dirt in joints with no sealant left, on copings & trims, façade panels and joints between brick and frames.
In and around a place like Muirhead, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Act on the first splits you see
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
What we are called out for in Muirhead
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
For landlords with property near Gartcosh station, outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- How long the guarantee is
- Are they insured?
When something else is needed
A few problems are outside what sealant work can do:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Muirhead buildings and the weather
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that will not mark it. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Managing a site like Chryston High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
