Outside joints around Barmulloch
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Glasgow’s tenements are largely red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that will not stain or attack it.
Historic houses such as Provand's Lordship, about 1.9 miles south-west, show how far back building around Barmulloch goes, and older homes nearby need a sealant that suits their walls.

External mastic for homes and businesses in Barmulloch
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. If you have failed sealant between panels on a façade and brick movement joints where the sealant has split, we can put it right, on façade panels, brickwork movement joints and concrete & block alike.
Gutters and downpipes on tall city tenements are a long way up, and a slow drip can stain and soak the stone for a long time before it’s spotted. For a building in Barmulloch, access is planned first, and shared parts may need the other owners to agree.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What else we do in Barmulloch
How we quote for external mastic
The quote reflects the job in front of us. We look at:
- Whether there’s mould to deal with
- How easy the joints are to reach
- The amount of work
- The type of sealant required
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- The type of property
- What’s wrong with the joints now
- Roughly how big the job is
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Do you need external mastic in Barmulloch?
Some movement joints have been pointed up with mortar. The joint cannot move, so the wall cracks somewhere else instead.
Most people get in touch after spotting one of these:
- Panel joints letting water in
- Hard, crazed mastic that has stopped moving
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
For landlords with property near Barnhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- How the colour is chosen
- What the cure time is
- How much experience the applicator has
- How the surfaces are prepared before sealing
Different surfaces, different methods
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and helps it last.
Your questions about external mastic in Barmulloch
Can you do external mastic in Barmulloch?
Yes, Barmulloch is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Barmulloch?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Barmulloch and the rest of Glasgow.
Is there a guarantee?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Never let anyone fill a movement joint with mortar
- Do not let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Landlord and commercial work in Barmulloch
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job normally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Barmulloch, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
