External mastic in Ardeer, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, render & cladding joints and concrete & block, and common reasons people get in touch are plants rooting in failed movement joints and hard, crazed mastic that has stopped moving.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Common questions in Ardeer
Does living near the coast affect external mastic in Ardeer?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will you come out to Ardeer?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it doesn’t stand out.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask before painting over external sealant
- Make sure movement joints are not pointed over
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
How we quote for external mastic
You will get a clear quote before work begins. It takes into account:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- The size of the job
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- A few pictures by email, if you can
- What’s wrong with the joints now
- Where the property is
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Do you need external mastic in Ardeer?
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
If you can see any of these, it’s time to have the joints looked at:
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
Schools such as Glencairn Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- How the colour is chosen
- Whether VAT is included
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
DIY versus a professional finish
The difference is mostly in the preparation and the 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What else we do in Ardeer
Ardeer buildings and the weather
Ardeer is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Montgreenan (about 4.5 miles north-east) nearby, there’s older building stock in the area around Ardeer as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Stevenston station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Ardeer Church Of Scotland include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
Ardeer is about 1 mile south-east of Stevenston, in North Ayrshire. Jobs in Ardeer get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Across North Ayrshire, we cover 53 places, Ardeer among them. We also work in Glasgow, around 24 miles away.
All of KA20 is covered for external mastic, from the main roads to the quietest streets. If you need external mastic at a property on Shore Road, Golf Avenue and Garven Road or a nearby road, our applicators can take on the job. Nearby, we also carry out external mastic in Stevenston (1 mile north-west), Auchenharvie (2 miles north-west), Kilwinning (2 miles north-east), Saltcoats (2 miles north-west) and Girdle Toll (3 miles east).

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
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Why act early in Ardeer
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

How the visit works
At the end, we look at the finished work together. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Mention any tricky access
