What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
External mastic in An Luirg
On houses, flats and commercial buildings across An Luirg, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on brickwork movement joints, copings & trims and render & cladding joints, and common reasons people get in touch are hard, crazed mastic that has stopped moving and damp patches traced to an open external joint.
External sealant needs dry surfaces, so outdoor work around An Luirg is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

FAQs for An Luirg
Is An Luirg within the area you cover?
Yes. An Luirg is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Lairg station. Can you help?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can I do it myself?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Adding movement joints to masonry that has none
- Damp that is not coming from the joint
- Failed render or damaged cladding panels
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
What we seal
- Façade panels
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like An Luirg, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep water from gutters off the wall
- Check external joints each spring
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
What external mastic looks like in An Luirg
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Lairg station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In and around An Luirg, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Outside jobs in An Luirg 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
