About our external mastic in Miabhaig
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. If you have damp patches traced to an open external joint and sealant that has lost its bond to the brick or render, we can put it right, whatever the surface.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Big or small, you get the same one-year guarantee in Miabhaig and across Na h-Eileanan Siar.

Outside joints around Miabhaig
Miabhaig is within about 1 mile of 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Around Miabhaig, as everywhere, external mastic is only as good as the preparation behind it.

FAQs for Miabhaig
Do you cover Miabhaig for external mastic?
Yes. Our work covers the whole of Scotland, and Miabhaig is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is external mastic in a coastal place like Miabhaig any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we will tell you how long to expect.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
Do you need external mastic in Miabhaig?
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
The most common problems we see are:
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
Whether the job is in Miabhaig itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- The length of the guarantee
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Are they insured?
Why it’s worth doing now in Miabhaig
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 so it’s worth doing right. In a place like Miabhaig, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Miabhaig may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- 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
- Mention any parking rules near the property
- Tell us about any water getting in
- Clear items away from the joints we’re working on

If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal

How to look after the new joints
A little care helps the new joints last. Our advice:
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
