External mastic in Birnam
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 strip the joint back and start again. If you have joints pointed up with cement by mistake and brick movement joints where the sealant has split, we can help.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Your questions about external mastic in Birnam
Will you come out to Birnam?
Yes. Birnam is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Birnam in your area for external mastic?
Yes. We work across all of Scotland, and Birnam is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How do I get a quote for external mastic in Birnam?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
What we are called out for in Birnam
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The most common problems we see are:
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
If you let a flat or house near Dunkeld & Birnam station, outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- How long to leave it before use
- What guarantee comes with the work
- How the surfaces are prepared before sealing
- What insurance they hold
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Copings & trims
Looking after it afterwards
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Wash walls gently around the sealant
- Point out the joints to other trades
- Keep water from gutters off the wall
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

Advice
Outside joints around Birnam
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 joints where harling meets other materials need a sealant that can grip and flex.
Around Birnam, as everywhere, external mastic is only as good as the preparation behind it.

DIY versus a professional finish
