About our external mastic in Clo Mhuillin
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. If you have rain getting behind render or cladding at a joint and old sealant gone brittle and cracked, we can help.
External sealant needs dry surfaces, so outdoor work around Clo Mhuillin is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

The process
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Move anything stored near the joints

Related advice
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What we’re called out for in Clo Mhuillin
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Most people get in touch after spotting one of these:
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
Homes close to Ardgour Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

FAQs for Clo Mhuillin
Is Clo Mhuillin in your area for external mastic?
Yes. We work across all of Scotland, and Clo Mhuillin is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is external mastic in a coastal place like Clo Mhuillin any different?
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.
How do I get a quote for external mastic in Clo Mhuillin?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
How do you reach high-level joints?
It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Highland.
What information do you need?
Tell us what needs doing and where. We will ask anything else we need to know.
Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a place like Clo Mhuillin, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Walk round the building once a year and look at the joints
- Keep high-pressure jets off the joints
- Fix overflowing gutters above sealed joints
- Make sure movement joints aren’t pointed over
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
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 it’s worth resealing at the first signs.
What else we do in Clo Mhuillin
How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Clo Mhuillin buildings and the weather
Clo Mhuillin 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 Clo Mhuillin, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
