External mastic for Scalasaig and the surrounding area: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way and it means sorting access once. In a place like Scalasaig, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why choose Mr Mastic in Scalasaig

External mastic in Scalasaig, done properly
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. If you are dealing with sealant pulling away from one side of the joint and moss and dirt in joints with no sealant left, we can put it right, on façade panels, render & cladding joints and brickwork movement joints alike.
In and around a place like Scalasaig, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
Every job comes with a one-year guarantee.

When to call us in Scalasaig
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
- Brick movement joints where the sealant has split
Around Scalasaig, as everywhere, external mastic is only as good as the preparation behind it.
What to look for in a quote
- What the cure time is
- What product goes in the joint
- What happens if they find a problem under the old sealant
- The length of the guarantee
Surface by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building. Outside jobs in Scalasaig need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
Getting a quote
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.
Related advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Make sure movement joints are not pointed over
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
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 early resealing is worth it.
External mastic in Scalasaig: local notes
Scalasaig is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you live in an older home near Scalasaig Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

FAQs for Scalasaig
Does living near the coast affect external mastic in Scalasaig?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Scalasaig?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
How much does external mastic cost in Scalasaig?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
