External mastic in Auchterderran
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you’re dealing with plants rooting in failed movement joints and brick movement joints where the sealant has split, we can put it right, whatever the surface.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Auchterderran
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Questions from Auchterderran
Is Auchterderran within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Cardenden station. Can you help?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
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.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
Can you quote for more than one area?
Yes. Just list everything you need.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you need external mastic in Auchterderran?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Common reasons people contact us include:
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
- Water getting into walls through failed joints
If you let a flat or house near Cardenden station, outside joints that have cracked can let damp into a rental, so check them between lets.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
- Damp that is not coming from the joint
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

What affects the cost of external mastic
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The size of the job
- Access and height
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

How the job changes by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Auchterderran buildings and the weather
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Lochgelly High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Auchterderran Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
