How we handle external mastic in Newlands
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We’re often asked to deal with rigid filler in a joint that should flex and failed seals between different materials, on render & cladding joints, copings & trims and brickwork movement joints.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Newlands, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Newlands buildings and 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. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Your title deeds say which parts are shared.
Rented homes near Langside station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Merrylea Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Hillpark Secondary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the job changes by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Newlands, damp can travel a long way before it shows.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Full insurance on every job

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What sealant work cannot fix
To be straight with you, there are a few things sealant will not fix:
- Render that’s blown, hollow or coming away
- Damp that is not coming from the joint
- Subsidence or other structural problems
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.

Common questions in Newlands
Do you cover Newlands for external mastic?

What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.
