Craigmarloch External Mastic
Professional external mastic in and around Craigmarloch, with old sealant always removed completely and a 12-month guarantee.
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Failed seals between different materials
External mastic in Craigmarloch
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. If you have leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving, we can put it right.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.

When to call us in Craigmarloch
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Most people get in touch after spotting one of these:
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
For landlords with property near Croy station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Your questions about external mastic in Craigmarloch
Will you come out to Craigmarloch?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Craigmarloch in your area for external mastic?
Yes. We work across all of Scotland, and Craigmarloch is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Are you fully insured?
Yes. We are fully insured.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
How long does external mastic take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across North Lanarkshire.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on.

Mention tracks, gates, ferries or anything else about the route.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.

Advice
What affects the quote in Craigmarloch
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- How many rooms, windows or areas are involved
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- A few photos by email, if you can
- If someone has resealed it before
- Access, such as stairs, a lift or height
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, drop us a line at info@mrmastic.co.uk.
What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Where we work in Craigmarloch
- Concrete & block
- Joints between brick and frames
- Façade panels
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Leave the joints unpainted unless we’ve said otherwise
- Do not let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
- Keep high-pressure jets off the joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.

External mastic in Craigmarloch: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For site and facilities teams at buildings such as Our Lady's High, its movement joints, gutters and trims need looking after like any other building’s.
