Do you need external mastic in Inveraldie?
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Signs it’s time to call us include:
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
For site and facilities teams at buildings such as Braeview Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic in Inveraldie, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on render & cladding joints, copings & trims and brickwork movement joints, and common reasons people get in touch are weathered mastic that no longer stretches and rain getting behind render or cladding at a joint.
External sealant needs dry surfaces, so outdoor work around Inveraldie is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
All of our work is guaranteed for twelve months.

FAQs for Inveraldie
Will you come out to Inveraldie?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Inveraldie in your area for external mastic?
Yes, Inveraldie is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
What’s an expansion joint in brickwork?
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.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Advice
What the job involves on each 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 where it can be done safely.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Quotes for external mastic in Inveraldie
Jobs vary more than people expect. What affects the quote:
- The size of the job
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove

- A few pictures by email, if you can

Honest limits
New sealant can’t fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Concrete & block
- Façade panels
- Brickwork movement joints
Why act early in Inveraldie
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In an older home around Inveraldie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Inveraldie buildings and the weather
Dundee sits on the north bank of the Tay, and much of its older housing is sandstone tenements, so movement joints and outside wall joints on walls facing the water can take plenty of weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Dundee station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Tealing Parish Church And Churchyard, older walls, gutters and the joints where extensions meet them need a flexible sealant.
