External Mastic in Kelvinside
Movement joints in Kelvinside need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
External mastic for homes and businesses in Kelvinside
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. If you’re dealing with joints pointed up with cement by mistake and weathered mastic that no longer stretches, we can put it right, on copings & trims, brickwork movement joints and façade panels alike.
Gutters and downpipes on tall city tenements are a long way up, and a slow drip can stain and soak the stone for a long time before it’s spotted. For a building in Kelvinside, access is planned first, and shared parts may need the other owners to agree.
Each job carries a 12-month guarantee, whatever its size.

When it is not the sealant
It helps to know what we can’t do:
- Damp that is not coming from the joint
- Cracked brickwork or render that needs a builder or plasterer
- Render that is blown, hollow or coming away
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
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. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
Why choose Mr Mastic in Kelvinside
- Sanitary silicone with an anti-fungal additive in wet areas
- Colour picked to suit the job
- Approved under the ARBOMaster scheme
- Old sealant always removed completely
Keeping the joints in good condition
So the new joints stay in good condition:
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Act on the first splits you see
- Walk round the building once a year and look at the joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it.
Your questions about external mastic in Kelvinside
Do you work for landlords with property near Hyndland station?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Can you do external mastic in Kelvinside?
Yes, Kelvinside is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, large or small.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Landlord and commercial work in Kelvinside
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
How the visit 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. For a tenement in Kelvinside, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Advice
Outside joints around Kelvinside
With historic houses such as Tenement House (about 1.8 miles south-east) nearby, there’s older building stock in the area around Kelvinside as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
For site and facilities teams at buildings such as Cleveden Secondary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Hyndland station? Then split movement joints are easy to miss on a rental until damp shows inside.

Common problems we fix in Kelvinside
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Joints with sealant missing in places
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
In the older streets around St John's Renfield Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
