About our external mastic in Linnvale
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 brickwork movement joints, façade panels and copings & trims, and common reasons people get in touch are brick movement joints where the sealant has split and failed sealant between panels on a façade.
Outside joints can only be sealed when they’re dry, so work in Linnvale depends on the weather. Let us know about access to every wall and roofline.
You are covered for a year from the day we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

What we cannot put right
Sealant is not the answer to every problem, and we will tell you before work begins. It will not solve:
- Cracks in the bricks or render themselves, away from the joints
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
What we seal
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
- Façade panels
- Concrete & block
Questions from Linnvale
Is Linnvale in your area for external mastic?
Yes, Linnvale is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Linnvale?
Yes. Linnvale is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What colours does the sealant come in?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
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. It all has to come out first.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Aftercare tips
A little care helps the new joints last. We recommend:
- Keep movement joints as flexible joints, not mortar
- Check external joints each spring
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
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. When it finally shows inside, the joint may have been open for years.

What else we do in Linnvale
Linnvale buildings and the weather
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Linnvale is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
For site and facilities teams at buildings such as Saint Andrew's High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Drumry station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Surface by surface
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
