External Mastic in Dyce
Movement joints in Dyce need attention? We cut out the old, prepare the joints and apply the right sealant.
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
External mastic in Dyce
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. If you are dealing with damp patches traced to an open external joint and rigid filler in a joint that should flex, we can put it right.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Dyce, repairs to shared parts are normally agreed between the owners, often through a property factor.
Big or small, it’s backed by our one-year guarantee.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What we’re called out for in Dyce
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Signs it’s time to call us include:
- Plants rooting in failed movement joints
- Panel joints letting water in
- Joints with sealant missing in places
- Movement joints filled with mortar instead of sealant
Managing a site like Dyce Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

Common questions in Dyce
Do you work for landlords with property near Dyce station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Dyce?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
How long does external mastic take?
Most jobs take anything from a few hours to several days, depending on the building. We will confirm how long when we quote.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How do I get a quote for external mastic in Dyce?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
What external mastic looks like in Dyce
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Your title deeds say which parts are shared. Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
Rented homes near Dyce station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

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.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
