Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
How we handle external mastic in Millport
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. If you’re dealing with rain getting behind render or cladding at a joint and movement joints with cracked, split or missing sealant, we can help, whatever the surface.
In and around a place like Millport, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Big or small, it’s backed by our 12-month guarantee in Millport and across North Ayrshire.

Why it’s worth doing now in Millport
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What happens on the day
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take anything from a few hours to several days, depending on the building. Around Millport, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- 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
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Questions from Millport
Will you come out to Millport?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Fairlie station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
How do I get a quote for external mastic in Millport?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we’ll do them. Tell us about the building and we will confirm what access is needed.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Walls and rooflines in Millport
Millport is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Fairlie station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Also in Millport
Do you need external mastic in Millport?
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we’re asked about most:
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
Mount Stuart House, about 4.6 miles north-west, is one of the historic houses in the wider area around Millport.

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
