- Water getting into walls through failed joints
External mastic in West Darlochan
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you have sealant that has lost its bond to the brick or render and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
Every job is covered by our 12-month guarantee, wherever you are in Argyll and Bute.

Why it’s worth doing now in West Darlochan
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. 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.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before work begins.
Why us?
- A choice of colours where the product allows
- Approved under the ARBOMaster scheme
- Fully insured
- Any old sealant cut out fully, not covered over

What we’re called out for in West Darlochan
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
The problems people generally mention when they call are:
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Failed seals between different materials
Around West Darlochan, as everywhere, external mastic is only as good as the preparation behind it.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the building. For a place like West Darlochan, longer drives are planned in advance. 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Try not to wet indoor joints just before the visit

West Darlochan questions
Is West Darlochan in your area for external mastic?
Yes, West Darlochan is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Does the coastal weather in West Darlochan 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.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How long does external mastic take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we’ll say how long yours will take.
How do I get a quote for external mastic in West Darlochan?
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. We agree the price before any work begins.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

What external mastic looks like in West Darlochan
West Darlochan is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you live in an older home near Kilchenzie Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
