External mastic in Brocketsbrae
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. If you have leaking joints around cladding and façade panels and joints pointed up with cement by mistake, we can help, whatever the surface.
In and around a place like Brocketsbrae, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
There’s a 12-month guarantee on every job, whatever its size.

Do you need external mastic in Brocketsbrae?
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
It’s worth asking for a quote if you see:
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
- Damp patches traced to an open external joint
Letting a property close to Lanark station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Before booking anyone
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- When the joint can take water or movement
- Whether they’re fully insured
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
What we seal
- Render & cladding joints
- Copings & trims
- Façade panels
- Brickwork movement joints
- Concrete & block
- Joints between brick and frames
What happens if it’s left?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. In an older home around Brocketsbrae, damp from a failed joint can get into timber and plaster.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.

What do you put in the joint?

Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins, matched as closely as the range allows.
What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the building. Outside jobs in Brocketsbrae need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Related advice
Brocketsbrae buildings and the weather
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Lesmahagow High School? Then larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Lesmahagow Old Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
