Advice
External mastic in Ardminish
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. Typical jobs include movement joints with cracked, split or missing sealant and moss and dirt in joints with no sealant left, on façade panels, brickwork movement joints and copings & trims.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
There’s a 12-month guarantee on every job, whatever its size.

What happens if it’s left?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In an older home around Ardminish, damp from a failed joint can get into timber and plaster.

How the job changes by surface
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly.
FAQs for Ardminish
Is Ardminish in your area for external mastic?
Yes. We work across all of Scotland, and Ardminish is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Does the coastal weather in Ardminish 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.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Ardminish.
Can you quote for more than one area?
Yes. Just list everything you need.
How much does external mastic cost in Ardminish?
Size, access and the old material all affect the cost. Ask us for a quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

What else we do in Ardminish
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Failed render or damaged cladding panels
- Damp that is not coming from the joint
- Movement that is more than a sealant joint can take
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Concrete & block
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
- Check external joints each spring
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
External mastic in Ardminish: local notes
Ardminish is close to 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Gigha Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. In and around Ardminish, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
