External mastic for homes and businesses in Garrowhill
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you have hard, crazed mastic that has stopped moving and weeds or debris growing in open joints, we can put it right.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
You get a one-year guarantee, the same in Garrowhill as everywhere else we work.

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way. In an older home around Garrowhill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

What the job involves on each surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
What we cannot put right
We will always be straight with you, so here’s what new sealant won’t do:
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on
- Copings & trims
- Concrete & block
- Façade panels
- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
DIY versus a professional finish
What a professional job adds is preparation and the right 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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Will there be a smell?

Do you work at height?
Each building is different. Tell us the height, the number of joints and what’s below them.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Outside joints around Garrowhill
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Bannerman High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St John's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Garrowhill station, split movement joints are easy to miss on a rental until damp shows inside.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off the joints
- Check external joints each spring
- Make sure movement joints aren’t pointed over
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
