External mastic in Craigcrook
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Common call-outs are for weathered mastic that no longer stretches and leaking joints around cladding and façade panels, on render & cladding joints, copings & trims and façade panels.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Craigcrook, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Can I do it myself?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What happens on the day
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases.

Your questions about external mastic in Craigcrook
Can you help a landlord with a rental near South Gyle station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
How do repairs to the shared parts of a tenement in Craigcrook get organised?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can usually cut it out and reseal it.
Do you come to Craigcrook?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
What is a movement joint?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Why deal with it now?
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. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Craigcrook, damp can travel a long way before it shows.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
What you get with us
- A choice of colours where the product allows
- An ARBOMaster approved applicator
- Arbo and Everbuild products
- A sealant colour to suit the surroundings

Craigcrook buildings and the weather
Craigcrook is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near South Gyle station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as The Mary Erskine School, its movement joints, gutters and trims need looking after like any other building’s.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
- Façade panels
- Render & cladding joints
Signs you need external mastic in Craigcrook
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
It’s worth asking for a quote if you see:
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
In the older streets around St Columba's Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- Whether you can choose the colour
- What the quote includes, VAT included or not
- How much experience the applicator has
- When the joint can take water or movement
