External mastic in Chapel of Garioch
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We’re often asked to deal with movement joints with cracked, split or missing sealant and rigid filler in a joint that should flex, across joints between brick and frames, copings & trims and concrete & block.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels

Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
Do you need external mastic in Chapel of Garioch?
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Hard, crazed mastic that has stopped moving
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
Letting a property close to Inverurie station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in Chapel of Garioch: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Homes close to Chapel Of Garioch include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Your questions about external mastic in Chapel of Garioch
I let a flat near Inverurie station. Can you help?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Can you do external mastic in Chapel of Garioch?
Yes. Our work covers the whole of Scotland, and Chapel of Garioch is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you work at height?
It depends on the building. Where joints can be reached safely, we’ll do them. Tell us about the building and we’ll confirm what access is needed.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. In a place like Chapel of Garioch, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
