How we handle external mastic in Catterline
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. We work on concrete & block, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are joints pointed up with cement by mistake and leaking joints around cladding and façade panels.
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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Catterline questions
Can you help a landlord with a rental near Stonehaven station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Is Catterline within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
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.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Landlord and commercial work in Catterline
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Make sure movement joints are not pointed over
- Leave the joints unpainted unless we have said otherwise
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.

What else we do in Catterline
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Catterline 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 look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
Getting a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
Related advice
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
Outside joints around Catterline
Catterline is within about 1 mile 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Stonehaven station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Catterline Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
