What external mastic looks like in An Tairbeart
An Tairbeart is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Arrochar & Tarbet station, split movement joints are easy to miss on a rental until damp shows inside.

External mastic in An Tairbeart, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on concrete & block, joints between brick and frames and render & cladding joints, and people most often call us about rigid filler in a joint that should flex and weathered mastic that no longer stretches.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
- Clear growth from the base of walls and joints
- Check external joints each spring
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
What we can’t put right
A few problems are outside what sealant work can do:
- Damp that isn’t coming from the joint
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

How it works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around An Tairbeart depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules

What the job involves on each surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
What we’re called out for in An Tairbeart
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Failed sealant between panels on a façade
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
In the older streets around Ballyhennan Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

An Tairbeart questions
Does living near the coast affect external mastic in An Tairbeart?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like An Tairbeart?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What affects the quote in An Tairbeart
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- The size of the job
- Mould in or behind the old joints
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Roughly how big the job is
- What’s wrong with the joints now
- Any previous sealing or DIY work
