External & façade joints in Old Balornock, Glasgow
Our applicators work in Old Balornock on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Damp that isn’t coming from the joint
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint

External mastic in Old Balornock
For buildings in Old Balornock, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on joints between brick and frames, brickwork movement joints and copings & trims, and people most often call us about old sealant gone brittle and cracked and sealant that has lost its bond to the brick or render.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Old Balornock, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.

What happens if it’s left?
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. For landlords in Old Balornock, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Common questions in Old Balornock
Do you work for landlords with property near Barnhill station?
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.
How do repairs to the shared parts of a tenement in Old Balornock get organised?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
What external mastic looks like in Old Balornock
With historic houses such as Provand's Lordship (about 0.8 miles south-west) nearby, there’s older building stock in the area around Old Balornock as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Your title deeds say which parts are shared.
If you look after a building such as St. Roch's Secondary School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Barnhill station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Our Lady of Good Counsel Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Check external joints each spring
- Deal with leaking gutters that soak the joints below
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Parking in city streets around Old Balornock can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
