- Failed sealant between panels on a façade
External mastic for homes and businesses in Greenloaning
Getting the depth right is half the job. 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. Typical jobs include failed sealant between panels on a façade and weeds or debris growing in open joints, on brickwork movement joints, copings & trims and façade panels.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

When to call us in Greenloaning
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Weeds or debris growing in open joints
- Failed seals between different materials
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
In the older streets around Greenloaning Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

When something else is needed
To be straight with you, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Damp that isn’t coming from the joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right 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.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a handful of joints, longer for a whole elevation. Around Greenloaning, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Advice
What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Outside joints around Greenloaning
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
In and around Greenloaning, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid pressure-washing directly into sealant joints
- Get split or bare joints resealed while the damage is small
- Make sure movement joints aren’t pointed over
- Walk round the building once a year and look at the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Greenloaning questions
Is Greenloaning within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What guarantee comes with external mastic in Greenloaning?
All our work, in Greenloaning and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
