About external mastic in Aberdeen
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We work on concrete & block, copings & trims and render & cladding joints, and common reasons people get in touch are panel joints letting water in and moss and dirt in joints with no sealant left.
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.

External mastic across Aberdeen: local notes
Aberdeen has everything from period brickwork to rendered and clad modern buildings. Where two materials meet is where water usually gets in.
The west of Scotland is wetter than the east, but outside joints take plenty of weather everywhere. Sealants for jobs in Aberdeen are chosen with that in mind. In the coastal parts of Aberdeen, the sea-facing side of a building takes the most weather, so they’re often the first to fail. Good preparation and the right sealant help it cope.
Aberdeen: For site and facilities teams at buildings such as Aberdeen Grammar School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to Rutherford Church And Church Hall include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
- Rising or penetrating damp from elsewhere in the wall
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Point out the joints to other trades
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we’ve said otherwise
- 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.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly.
Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself.

Questions from Aberdeen
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before work begins, matched as closely as the range allows.
Where are you based?
Mr Mastic is based in Crawley. We cover Aberdeen, along with the rest of our area.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you have insurance?
Yes. We’re fully insured.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
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.
