External mastic in Kirkton of Maryculter, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have failed sealant between panels on a façade and rain getting behind render or cladding at a joint, we can help, whatever the surface.
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.
There’s a 12-month guarantee on every job.

When to call us in Kirkton of Maryculter
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
These are the problems we’re asked about most:
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
Managing a site like International School of Aberdeen? Then its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- Whether all the old sealant comes out first
- When the joint can take water or movement
- The length of the guarantee
- Who does the work, and how experienced they are
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep high-pressure jets off the joints
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
What external mastic looks like in Kirkton of Maryculter
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Portlethen station? Then split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Maryculter Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a place like Kirkton of Maryculter, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

What we can’t put right

- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
