External mastic in Dundonald, done properly
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 and we use one wherever it does. We work on façade panels, joints between brick and frames and brickwork movement joints, and people most often call us about failed seals between different materials and panel joints letting water in.
External sealant needs dry surfaces, so outdoor work around Dundonald is planned around the weather. Tell us how to reach each wall, gutter and roofline.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
What else we do in Dundonald
External mastic in Dundonald: local notes
Dundonald is within about 3 miles of 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. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Letting a property close to Barassie station? Then split movement joints are easy to miss on a rental until damp shows inside. Homes close to Dundonald Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Dundonald questions
Do you work for landlords with property near Barassie station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Is Dundonald within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What affects the quote in Dundonald
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- The number of rooms or windows
- Which sealant suits the joint
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
What to tell us when you ask for a quote:
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Where the job is, and your postcode
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
For landlords and businesses
If you manage several properties in or around Dundonald, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
When it is not the sealant
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Around Dundonald, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children

Advice
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What happens if it’s left?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. 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.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
