About our external mastic in Ballachulish
For buildings in Ballachulish, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We’re often asked to deal with sealant pulling away from one side of the joint and brick movement joints where the sealant has split, across joints between brick and frames, render & cladding joints and copings & trims.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job normally takes a few hours to a few days, depending on the length of joint and the access. Outside jobs in Ballachulish 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 is not affected.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Advice
Aftercare tips
Good habits help new joints last longer. A few tips:
- Point out the joints to other trades
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.

Outside joints around Ballachulish
Ballachulish is within about 1 mile of 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. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Whether the job is in Ballachulish itself or nearby, the right material for each joint matters as much as a neat finish.

Common questions in Ballachulish
Will you come out to Ballachulish?
Yes. Ballachulish 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.
Does the coastal weather in Ballachulish affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Signs you need external mastic in Ballachulish
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
People generally contact us after spotting one of these:
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
Around Ballachulish, as everywhere, external mastic is only as good as the preparation behind it.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What we need to know
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- Where the property is

- Access, such as stairs, a lift or height
Every job is quoted individually. Simply send an email to info@mrmastic.co.uk and describe the job.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. In a place like Ballachulish, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
