Walls and rooflines in Irvine
Irvine is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Irvine is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
If you look after a building such as Greenwood Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Montgreenan, about 3.2 miles north, show how far back building around Irvine goes.

External mastic in Irvine, done properly
For buildings in Irvine, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on render & cladding joints, copings & trims and joints between brick and frames, and common reasons people get in touch are rigid filler in a joint that should flex and moss and dirt in joints with no sealant left.
In a town like Irvine, plenty of homes have harled (roughcast) walls, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Rooflines take their share of the weather as well.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Other services in Irvine
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. Parking around Irvine is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Mention if the joints have been sealed before

Advice
When to call us in Irvine
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. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Panel joints letting water in
If you let a flat or house near Irvine station, split movement joints are easy to miss on a rental until damp shows inside.

When it is not the sealant
A few problems are outside what sealant work can do:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

What affects the quote in Irvine
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How much there is to do
- Mould in or behind the old joints
- How easy the joints are to reach
- The old material and how stubborn it is
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- If someone has resealed it before
- Where the property is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
FAQs for Irvine
Does living near the coast affect external mastic in Irvine?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Irvine station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
How do I get a quote for external mastic in Irvine?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Why deal with it now?
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 pays to do it properly once. If you live in a flat in Irvine, failed sealant can send water to the neighbours below, which turns a small job into a bigger one.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we’ve said otherwise
- Keep movement joints as flexible joints, not mortar
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
