External mastic in High Earnock, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on joints between brick and frames, concrete & block and façade panels, and common reasons people get in touch are sealant that has lost its bond to the brick or render and weathered mastic that no longer stretches.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. 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 isn’t right with it, email us at info@mrmastic.co.uk.

What affects the cost of external mastic
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- The type of sealant required
- Whether there’s mould to deal with
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
Helping us quote
To help us quote quickly, let us know:
- The type of property

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, email us at info@mrmastic.co.uk.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Make sure movement joints aren’t pointed over
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Don’t let climbing plants root in the sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.

Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.

What external mastic looks like in High Earnock
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Managing a site like Earnock High School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Hamilton West station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Advice
Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What we can’t put right
Before you book, it’s worth knowing the limits:
- Subsidence or other structural problems

- Loose or hollow render, which needs re-rendering
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
