External mastic in Rosshall: local notes
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. The title deeds set out which parts are common. 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 Rosshall Academy? Then larger buildings have long runs of movement joint that eventually need resealing. Historic houses such as Pollok House, about 2 miles south-east, show how far back building around Rosshall goes, and older homes nearby need a sealant that suits their walls. Rented homes near Crookston station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Wind-driven rain gets into any failed joint on the outside of a city building, and in Rosshall, damp can spread through stone and plaster before anyone sees it.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Parking in city streets around Rosshall can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Leave the joints unpainted unless we have said otherwise
- Have failed joints looked at early
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

Can you help a landlord with a rental near Crookston station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
How do repairs to the shared parts of a tenement in Rosshall get organised?
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.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
