Anderston External Mastic
External mastic across Anderston and nearby, with old sealant always removed completely and a 12-month guarantee.
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Cracked joints where brick meets render or frames
What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
External mastic in Anderston, done properly
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. Typical jobs include cracked joints where brick meets render or frames and panel joints letting water in, across brickwork movement joints, façade panels and concrete & block.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Anderston, repairs to shared parts are generally agreed between the owners, often through a property factor.
Whatever the size of the job, you get the same 12-month guarantee in Anderston and across Glasgow.

Common questions in Anderston
Do you cover Anderston for external mastic?
Yes, Anderston 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.
Who arranges sealant work on the shared parts of a tenement in Anderston?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
How do I get a quote for external mastic in Anderston?
Size, access and the old material all affect the cost. Ask us for a quote.
Do you need external mastic in Anderston?
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
The problems people generally mention when they call include:
- Panel joints letting water in
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
If you look after a building such as Glasgow Academy, its movement joints, gutters and trims need looking after like any other building’s.
Before you book anyone
- Whether the sealant suits the joint
- Whether VAT is included
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Anderston, damp can travel a long way before it shows.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

How it works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a tenement in Anderston, 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.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Clear the area around the work

Walls and rooflines in Anderston
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that will not stain or attack it.
Tenement House, about 0.1 miles north, is one of the historic houses in the wider area around Anderston, and older homes nearby need a sealant that suits their walls. For landlords with property near Charing Cross (Glasgow) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
