About our external mastic in North Kelvinside
For buildings in North Kelvinside, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. Common call-outs are for weeds or debris growing in open joints and joints with sealant missing in places, on joints between brick and frames, façade panels and concrete & block.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around North Kelvinside, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Whatever the size of the job, it’s backed by our 12-month guarantee in North Kelvinside and across Glasgow.

The work usually takes anything from a few hours to several days, depending on the building. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In North Kelvinside, it helps to know the floor, the door entry arrangements and the nearest parking.

Common problems we fix in North Kelvinside
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Most people get in touch when they notice one of these:
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
For landlords with property near Possilpark & Parkhouse station, split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether the sealant suits the joint

How the job changes by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. For landlords in North Kelvinside, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.

Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
