External mastic in Gowkhall
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We are often asked to deal with plants rooting in failed movement joints and hard, crazed mastic that has stopped moving, on copings & trims, brickwork movement joints and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Gowkhall depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
You get a 12-month guarantee, the same in Gowkhall as everywhere else we work.

What we are called out for in Gowkhall
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Plants rooting in failed movement joints
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
Letting a property close to Dunfermline City station? Then split movement joints are easy to miss on a rental until damp shows inside.

What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
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 so neither cracks the other.
Honest limits
It helps to know what we cannot do:
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Outdoor work around Gowkhall depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Keep children and pets away from the work area
- Mention any parking rules near the property
- On commercial sites, let us know about site rules

What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. 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.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

Questions from Gowkhall
Can you help a landlord with a rental near Dunfermline City station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Is external mastic in a coastal place like Gowkhall any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you insured?
Yes, we’re fully insured for every job we do.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins.
Do you work at height?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Walls and rooflines in Gowkhall
Gowkhall is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you live in an older home near Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Queen Anne High School Dunfermline, larger buildings have long runs of movement joint that eventually need resealing.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
