What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
External mastic in Barcaldine, done properly
On houses, flats and commercial buildings across Barcaldine, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you’re dealing with joints with sealant missing in places and panel joints letting water in, we can put it right, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
All our work is covered by our one-year guarantee, wherever you are in Argyll and Bute.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Barcaldine questions
Is Barcaldine in your area for external mastic?
Yes, Barcaldine is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Is external mastic in a coastal place like Barcaldine any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
External mastic in Barcaldine: local notes
Barcaldine is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
In and around Barcaldine, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. Whether the job is in Barcaldine itself or nearby, the right material for each joint matters as much as a neat finish.

Why act early in Barcaldine
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
How it works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Mention any tricky access

Aftercare tips
To keep the joints looking good and working properly:
- Point out the joints to other trades
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
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, all bigger jobs than a reseal.
