About our external mastic in Barrmill
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 where a rigid filler would soon crack. Typical jobs include leaking joints around cladding and façade panels and sealant that has lost its bond to the brick or render, on copings & trims, joints between brick and frames and concrete & block.
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.
You are covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. In an older home around Barrmill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Colour agreed with you before we start
- Experience in homes, commercial sites and hotels

What sealant work can’t fix
We will not take on work that won’t last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

How it works
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Somewhere like Barrmill may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on

What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
DIY versus a professional finish
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 a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
External mastic in Barrmill: local notes
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.
If you look after a building such as Spier's School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Dunlop station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Montgreenan, about 4.6 miles south, is one of the historic houses in the wider area around Barrmill.

How we quote for external mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How many rooms, windows or areas are involved
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Helping us quote
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- The address or postcode of the job
- The problem you’ve noticed
