- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
Why act early in Roughmussel
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Private landlords in Roughmussel must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

External mastic for homes and businesses in Roughmussel
On houses, flats and commercial buildings across Roughmussel, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on joints between brick and frames, concrete & block and render & cladding joints, and people most often call us about gaps where render, brick and frames meet and plants rooting in failed movement joints.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Roughmussel, those joints dry out over time and let water in behind the render or cladding.
You get a 12-month guarantee, the same in Roughmussel as everywhere else we work.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. In a city area like Roughmussel, parking may be by permit or pay-and-display, so tell us what’s nearby. 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.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

Walls and rooflines in Roughmussel
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. Your title deeds say which parts are shared. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Letting a property close to Nitshill station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as St. Paul's High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Roughmussel questions
Who arranges sealant work on the shared parts of a tenement in Roughmussel?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Do you work for landlords with property near Nitshill station?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
How do I get a quote for external mastic in Roughmussel?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Quotes for external mastic in Roughmussel
There’s no set price list. What we look at:
- The old material and how stubborn it is
- The number of rooms or windows
- Whether the work is at height
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Where the job is, and your postcode
- A few pictures by email, if you can
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
What we can’t put right
We won’t take on work that will not last, so these are the limits:
- Damp that is not coming from the joint
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

When to call us in Roughmussel
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Joints with sealant missing in places
- Plants rooting in failed movement joints
Historic houses such as Pollok House, about 1.8 miles east, show how far back building around Roughmussel goes.
