External mastic for homes and businesses in Head of Muir
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and people most often call us about joints where the bead has come unstuck and failed seals between different materials.
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.
Every job comes with a 12-month guarantee.

External mastic in Head of Muir: local notes
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Larbert station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Bonnybridge Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

When to call us in Head of Muir
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
For site and facilities teams at buildings such as Denny High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Head of Muir
Do you cover Head of Muir for external mastic?
Yes. We work across all of Scotland, and Head of Muir is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Head of Muir?
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.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Head of Muir.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Have failed joints looked at early
- Keep high-pressure jets off the joints
- Don’t let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Why act early in Head of Muir
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like Head of Muir, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.

What happens on the day
We bring everything the job needs with us. 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. Outdoor work around Head of Muir depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
