Walls and rooflines in Pitcairngreen
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of 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.
Managing a site like Bertha Park High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

About our external mastic in Pitcairngreen
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Typical jobs include movement joints with cracked, split or missing sealant and cracked joints where brick meets render or frames, across brickwork movement joints, façade panels and concrete & block.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
All our work comes with our 12-month guarantee, wherever you are in Perth and Kinross.

When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

What else we do in Pitcairngreen
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 matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep water from gutters off the wall
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Around Pitcairngreen, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

Pitcairngreen questions
Do you cover smaller places like Pitcairngreen?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Pitcairngreen for external mastic?
Yes. Our work covers the whole of Scotland, and Pitcairngreen is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
What we’re called out for in Pitcairngreen
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
These are the problems we are asked about most:
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
For landlords with property near Perth station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
