What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

External mastic in Blarmachfoldach
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on façade panels, brickwork movement joints and concrete & block, and the jobs we see most are panel joints letting water in and sealant pulling away from one side of the joint.
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.
Whatever the size of the job, you get the same 12-month guarantee in Blarmachfoldach and across Highland.

How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- The product the joint needs
- The amount of work
- Access and height
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
Before you ask for a quote, have a think about:
- If someone has resealed it before
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Aftercare tips
A little care helps the new joints last. Our advice:
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
- Get split or bare joints resealed while the damage is small
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Blarmachfoldach: your questions answered
Is external mastic in a coastal place like Blarmachfoldach any different?
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.
Can you help a landlord with a rental near Fort William station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What should I tell you?
A short description and the location, plus photos if you have them. If we need more, we will ask.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Signs you need external mastic in Blarmachfoldach
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint.
Look out for any of the following:
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Sealant pulling away from one side of the joint
- Leaking joints around cladding and façade panels
Rented homes near Fort William station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What else we do in Blarmachfoldach
Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
Walls and rooflines in Blarmachfoldach
Blarmachfoldach is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Blarmachfoldach is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
