Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant isn’t too deep.
About our external mastic in Millmannoch
On houses, flats and commercial buildings across Millmannoch, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on façade panels, brickwork movement joints and joints between brick and frames, and the jobs we see most are rain getting behind render or cladding at a joint and weathered mastic that no longer stretches.
External sealant needs dry surfaces, so outdoor work around Millmannoch is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Whatever the size of the job, you get the same one-year guarantee in Millmannoch and across South Ayrshire.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What external mastic looks like in Millmannoch
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Millmannoch is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Around Millmannoch, as everywhere, external mastic is only as good as the preparation behind it.
Millmannoch is about 6 miles east of Ayr, in South Ayrshire.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we’ve said otherwise
- Make sure movement joints aren’t pointed over
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Common questions in Millmannoch
Is Millmannoch in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Millmannoch is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Is there a guarantee on external mastic in Millmannoch?
All our work, in Millmannoch and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long will you be here?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. Your quote will say how long we expect yours to take.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them.
What we cannot put right
It helps to know what we cannot do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Failed render or damaged cladding panels
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on

What else we do in Millmannoch
What we’re called out for in Millmannoch
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Joints where the bead has come unstuck
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Failed seals between different materials
For jobs in and around Millmannoch, choosing the right material for each joint is as important as a tidy finish.
