What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.

External mastic for homes and businesses in Newbank
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you have movement joints filled with mortar instead of sealant and old sealant gone brittle and cracked, we can help, whatever the surface.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Newbank, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Whatever the size of the job, you get the same one-year guarantee.

Your questions about external mastic in Newbank
Who arranges sealant work on the shared parts of a tenement in Newbank?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
I let a flat near Duke Street station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Newbank and the rest of Glasgow, along with the rest of our area.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
What we cannot put right
It helps to know what we can’t do too:
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.

What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access. In a city area like Newbank, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Advice
Walls and rooflines in Newbank
With historic houses such as Provand's Lordship (about 1.7 miles north-west) nearby, there’s older building stock in the area around Newbank as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Newbank is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Common problems we fix in Newbank
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Keep an eye out for any of the following:
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
If you look after a building such as St Mungo's Academy, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- When the joint can take water or movement
- How the colour is chosen
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
