About our external mastic in Braehead
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Common call-outs are for sealant that has lost its bond to the brick or render and gaps where render, brick and frames meet, on render & cladding joints, concrete & block and joints between brick and frames.
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.
All of our work is guaranteed for twelve months.

What external mastic looks like in Braehead
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Carstairs station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Leave it or put it right?
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. In an older home around Braehead, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a place like Braehead, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- 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.
Getting ready for the visit
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Your questions about external mastic in Braehead
Do you cover Braehead for external mastic?
Yes, Braehead is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is Braehead within the area you cover?
Yes. Braehead is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Are you insured?
Yes, we are fully insured.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
When to call us in Braehead
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Any of these means the joints need attention:
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
If you live in an older home near Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before booking
- Whether VAT is included
- Whether the sealant suits the joint
- Are they insured?
- How much experience the applicator has
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Show decorators and builders where the movement joints are
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Ask before painting over external sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
For landlords and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
