About our external mastic in Avoch
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, and when it fails, the wall takes the strain and water finds a way in. We’re often asked to deal with old sealant gone brittle and cracked and joints pointed up with cement by mistake, across brickwork movement joints, copings & trims and concrete & block.
In and around a place like Avoch, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is generally less of an issue than access and distance. 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.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Tell us about any water getting in

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
FAQs for Avoch
Is Avoch in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Avoch is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.

How do you reach high-level joints?
It depends on the building. Send us photos and a rough idea of the height and we’ll confirm how they can be reached safely.
Can landlords and businesses book you?

Are you fully insured?
Yes. Mr Mastic is fully insured.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Aftercare tips
After the cure time, these simple habits help:
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
- Get split or bare joints resealed while the damage is small
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
External mastic in Avoch: local notes
Avoch is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Around Avoch, as everywhere, external mastic is only as good as the preparation behind it. For jobs in and around Avoch, choosing the right material for each joint is as important as a tidy finish.

Why act early in Avoch
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What affects the cost of external mastic
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Whether the work is at height
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
When you call or email, these details help:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- The rough size of the job
- Whether it has been sealed before
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear quote.
What the job involves on each surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
