Problem with your movement joints in Muirend? We cut out the old, prepare the joints and apply the right sealant.

External mastic in Muirend, done properly
On houses, flats and commercial buildings across Muirend, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on façade panels, joints between brick and frames and concrete & block, and people most often call us about sealant pulling away from one side of the joint and hard, crazed mastic that has stopped moving.
On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. In Muirend, access needs planning, and work on shared parts may need the other owners’ agreement.
All of our work is guaranteed for twelve months.

- Any mould that needs treating
- How many areas need sealing
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Do you need external mastic in Muirend?
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
People usually contact us after spotting one of these:
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
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.

Muirend: your questions answered
I let a flat near Muirend station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Muirend?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Looking after it afterwards
To keep the joints looking good and working properly:
- Act on the first splits you see
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
- Ask before painting over external sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

What external mastic looks like in Muirend
With historic houses such as Pollok House (about 1.9 miles north-west) nearby, there’s older building stock in the area around Muirend as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For site and facilities teams at buildings such as Hillpark Secondary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Muirend station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How it works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building for a typical job. Parking in city streets around Muirend can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

Advice
Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a tenement flat in Muirend, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
