How we handle external mastic in Rubha Ban
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall. If you have joints where the bead has come unstuck and leaking joints around cladding and façade panels, we can help, whatever the surface.
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.

External mastic in Rubha Ban: local notes
Rubha Ban is within about 2 miles of 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. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
For an older house near a landmark such as St Michael's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Do you need external mastic in Rubha Ban?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
Around Rubha Ban, as everywhere, external mastic is only as good as the preparation behind it.

Why it’s worth doing now in Rubha Ban
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What happens on the day
When we arrive, we start by going over the job with you. 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. Around Rubha Ban, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on

Related advice
DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
When something else is needed
In fairness, some problems need a different trade:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Rubha Ban: your questions answered
Is Rubha Ban in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Rubha Ban is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Does the coastal weather in Rubha Ban affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I add another job to the visit?
Yes. Just list everything you need.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall and the joint fails. If it has already been filled, we can usually cut it out and reseal it.
