External mastic in Balmullo
On houses, flats and commercial buildings across Balmullo, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on façade panels, copings & trims and concrete & block, and people most often call us about leaking joints around cladding and façade panels and sealant that has lost its bond to the brick or render.
In and around a place like Balmullo, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

What happens if it’s left?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why book with us
- Tidy, careful work
- Fully insured
- Quality sealants from Arbo and Everbuild
- White, clear, grey or coloured to suit, where the product allows

Looking after it afterwards
To keep the joints looking good and working properly:
- Leave the joints unpainted unless we’ve said otherwise
- Never let anyone fill a movement joint with mortar
- Clear growth from the base of walls and joints
- Check external joints each spring
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere like Balmullo may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at every joint and agree a colour to suit the wall.
- 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
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Quotes for external mastic in Balmullo
We do not publish a price list, because jobs vary so much. The quote depends on:
- Which sealant suits the joint
- Any mould that needs treating
- When we can work, for business premises
- The amount of work
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

How the job changes by surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Send us any details you have about the façade.
External mastic in Balmullo: local notes
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Leuchars station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Balmullo questions
Is Balmullo in your area for external mastic?
Yes, Balmullo is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
I let a flat near Leuchars station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can email us at info@mrmastic.co.uk with the details for a clear quote.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do you use backing rod?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
Common problems we fix in Balmullo
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Most people get in touch when they notice something like this:
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
In and around Balmullo, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
