- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.

External mastic in Caiystane
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and the jobs we see most are brick movement joints where the sealant has split and panel joints letting water in.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Caiystane, repairs to shared parts are normally agreed between the owners, often through a property factor.
Big or small, it’s backed by our 12-month guarantee in Caiystane and across Edinburgh.

DIY sealant or a professional job?
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, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Walls and rooflines in Caiystane
Historic houses like Whitefoord House (about 3.6 miles north) are a reminder that the area around Caiystane has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
In the older streets around Fairmilehead Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Slateford station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Firrhill High School, its movement joints, gutters and trims need looking after like any other building’s.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Tell anyone working on the walls about the movement joints
- Check the sealant is paintable before painting near it
- Don’t let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
Caiystane: your questions answered
How is work on the outside of a tenement in Caiystane normally arranged?
The owners of the flats generally 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 do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
Do you cover Caiystane for external mastic?
Yes. We work across all of Scotland, and Caiystane is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before work begins. It will not solve:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.
