External mastic in Greenfaulds, done properly
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you are dealing with joints pointed up with cement by mistake and hard, crazed mastic that has stopped moving, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Greenfaulds depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Whatever the size of the job, you get the same one-year guarantee in Greenfaulds and across North Lanarkshire.

Aftercare tips
Aftercare is simple:
- Make sure movement joints aren’t pointed over
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
- Keep soil, plants and ivy away from the joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. At that stage it’s a simple cut out and reseal.

What we cannot put right
Sealant is not the answer to every problem, and we’ll tell you before we start. It will not solve:
- Failed render or damaged cladding panels
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Copings & trims
- Concrete & block
- Brickwork movement joints
What external mastic looks like in Greenfaulds
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you live in an older home near St Mungo's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Greenfaulds High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Greenfaulds station, outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Greenfaulds questions
Is Greenfaulds in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Greenfaulds is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you come out to Greenfaulds?
Yes. Greenfaulds is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work at height?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
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.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Greenfaulds depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
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.
