How we handle external mastic in Braehead
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. We work on brickwork movement joints, joints between brick and frames and copings & trims, and the jobs we see most are failed sealant between panels on a façade and damp patches traced to an open external joint.
Outside joints can only be sealed when they’re dry, so work in Braehead depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

External mastic in Braehead: local notes
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. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Pollok House, about 4.9 miles north-west, is one of the historic houses in the wider area around Braehead, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as Duncanrig Secondary School, its movement joints, gutters and trims need looking after like any other building’s.
Braehead is about 2 miles north-west of Mossneuk, in South Lanarkshire. Every kind of property in Braehead is covered for external mastic, old or new, large or small. The work is guaranteed for a year. Braehead is one of 139 towns and villages in South Lanarkshire where we work. Glasgow is on our list too, about 6 miles from Braehead.

Why act early in Braehead
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Around Braehead, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why choose Mr Mastic in Braehead
- White, clear, grey or another colour, product permitting
- Sanitary silicone with an anti-fungal additive in wet areas

How the job changes by surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Questions from Braehead
I let a flat near Thorntonhall station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Will you come out to Braehead?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
How long does external mastic take?
Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will say how long yours will take.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Somewhere like Braehead 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.

When to call us in Braehead
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Look out for any of the following:
- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
If you let a flat or house near Thorntonhall station, outside joints that have cracked can let damp into a rental, so check them between lets.

When it is not the sealant
To be straight with you, some problems need a different trade:
