- Mould in or behind the old joints
- How much there is to do
- Any working-time requirements on site
Some things make a job bigger or smaller: 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.

To help us quote quickly, let us know:
- If someone has resealed it before
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Any access issues, like height or stairs

How we handle external mastic in Craigend
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Typical jobs include plants rooting in failed movement joints and hard, crazed mastic that has stopped moving, across joints between brick and frames, copings & trims and façade panels.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Craigend, those joints dry out over time and let water in behind the render or cladding.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Inside a flat in Craigend, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Advice
What we are called out for in Craigend
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Keep an eye out for these signs:
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
For landlords with property near Robroyston station, outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- How long the guarantee is
- Are they insured?
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
Craigend questions
I let a flat near Robroyston station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
How do repairs to the shared parts of a tenement in Craigend 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, and we can quote for the factor or the owners directly.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How long does external mastic take?
That depends on the amount of work, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

What else we do in Craigend
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act on the first splits you see
- Keep high-pressure jets off the joints
- Do not let climbing plants root in the sealant
- Make sure movement joints aren’t pointed over
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
What sealant work cannot fix
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Walls that need new movement joints cut into them
- Damp that isn’t coming from the joint
- Movement that’s more than a sealant joint can take
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

Outside joints around Craigend
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Historic houses such as Provand's Lordship, about 3.1 miles west, show how far back building around Craigend goes, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as St Andrew's Secondary School, larger buildings have long runs of movement joint that eventually need resealing.
