External mastic for homes and businesses in High Ruchill
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Common call-outs are for leaking joints around cladding and façade panels and movement joints filled with mortar instead of sealant, on copings & trims, façade panels and joints between brick and frames.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. For a tenement in High Ruchill, repairs to shared parts are generally agreed between the owners, often through a property factor.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Fix overflowing gutters above sealed joints
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we have said otherwise
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
External mastic in High Ruchill: local notes
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Cleveden Secondary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Gilshochill station? Then split movement joints are easy to miss on a rental until damp shows inside.

Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.

Advice

What we are called out for in High Ruchill
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Look out for any of the following:
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
For an older house near a landmark such as Ruchill Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- The amount of work
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- Whether the work is at height
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
What we need to know
When you call or email, it’s useful to know:
- The rough size of the job
- Where the property is
- The type of property
- Any access issues, like height or stairs
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, drop us a line at info@mrmastic.co.uk.
What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. For landlords in High Ruchill, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Questions from High Ruchill
How do repairs to the shared parts of a tenement in High Ruchill 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 do not.
Is High Ruchill in your area for external mastic?
Yes. We work across all of Scotland, and High Ruchill is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
