How we handle external mastic in Ardfern
Low-level joints can normally be done from the ground. 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 leaking joints around cladding and façade panels and weeds or debris growing in open joints, across façade panels, joints between brick and frames and brickwork movement joints.
In and around a place like Ardfern, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we are called out for in Ardfern
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Weeds or debris growing in open joints
- Weathered mastic that no longer stretches
- Panel joints letting water in
- Failed seals between different materials
Around Ardfern, as everywhere, external mastic is only as good as the preparation behind it.

What affects the cost of external mastic
Your quote is based on your job. We look at:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Whether there’s mould to deal with
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- The rough size of the job
- The problem you’ve noticed
- If someone has resealed it before
If you’re in Ardfern and need external mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
The process
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Around Ardfern, 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.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Advice
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
What we can’t put right
We will not take on work that will not last, so these are the limits:
- Movement that is more than a sealant joint can take
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why it’s worth doing now in Ardfern
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. Around Ardfern, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Ardfern buildings and the weather
Ardfern 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. Ardfern 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.
In the older streets around Craignish Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Ardfern: your questions answered
Is Ardfern in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Ardfern is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is external mastic in a coastal place like Ardfern 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. Walls facing the sea are generally the first to need attention.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
