External & façade joints in Charleston, Dundee

What external mastic looks like in Charleston
Charleston is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Schools such as Menzieshill High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Homes close to Lochee Baptist Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Charleston
For buildings in Charleston, 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. If you have sealant pulling away from one side of the joint and movement joints with cracked, split or missing sealant, we can help, on brickwork movement joints, render & cladding joints and façade panels alike.
Gutters and downpipes on tall city tenements are a long way up, so a leaking joint can run down the stone for months before anyone notices. For a building in Charleston, access is planned first, and shared parts may need the other owners to agree.
You’re covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Charleston: your questions answered
How do repairs to the shared parts of a tenement in Charleston get organised?
It generally 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 do not, and we can quote for the factor or the owners directly.
Do you work for landlords with property near Invergowrie station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
What does external mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What happens on the day
The work is kept neat and contained to the joints we are treating. The job normally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Charleston, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Tell us if parking is tricky

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Private landlords in Charleston must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.

When to call us in Charleston
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.
Keep an eye out for these signs:
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Joints with sealant missing in places
- Plants rooting in failed movement joints
For landlords with property near Invergowrie station, outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
