Why act early in Ballumbie
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Ballumbie, damp can travel a long way before it shows.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

External mastic in Ballumbie
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on façade panels, brickwork movement joints and render & cladding joints, and common reasons people get in touch are rain getting behind render or cladding at a joint and movement joints filled with mortar instead of sealant.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. For a building in Ballumbie, access is planned first, and shared parts may need the other owners to agree.
Big or small, you get the same one-year guarantee in Ballumbie and across Dundee.

What else we do in Ballumbie
External mastic in Ballumbie: local notes
Ballumbie is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
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.

Your questions about external mastic in Ballumbie
Does the coastal weather in Ballumbie affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
I let a flat near Broughty Ferry station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How long does external mastic take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
How we quote for external mastic
Your quote is based on your job. We look at:
- The type of sealant required
- The old material and how stubborn it is
- Whether there’s mould to deal with
- When we can work, for business premises
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- The type of property
- How we’d reach the joints
- If someone has resealed it before

Aftercare tips
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Check external joints each spring
- Wash walls gently around the sealant
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we’re called out for in Ballumbie
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
The problems people generally mention when they call include:
- Failed sealant between panels on a façade
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
Rented homes near Broughty Ferry station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Ballumbie, tell us the floor, how the door entry system works and where we can park nearby.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
