How the job changes by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
External mastic in Tradeston
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We are often asked to deal with gaps where render, brick and frames meet and plants rooting in failed movement joints, on copings & trims, concrete & block and render & cladding joints.
On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. In Tradeston, access needs planning, and work on shared parts may need the other owners’ agreement.
All of our work is guaranteed for twelve months.

Aftercare tips
A little care helps the new joints last. Our advice:
- Keep soil, plants and ivy away from the joints
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we have said otherwise
- Make sure movement joints are not pointed over
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Honest limits
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.

How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. Parking in city streets around Tradeston can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

Advice
Questions from Tradeston
Who arranges sealant work on the shared parts of a tenement in Tradeston?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can you do external mastic in Tradeston?
Yes. We work across all of Scotland, and Tradeston is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
What is a movement joint?
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.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Walls and rooflines in Tradeston
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Glasgow Central station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Our Lady and St Margaret's Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Tenement House, about 1.1 miles north, is one of the historic houses in the wider area around Tradeston, and older homes nearby need a sealant that suits their walls.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
