External Mastic in Fairlie
Movement joints in Fairlie need attention? We remove the old material, prepare the joints and seal them properly.

When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
- Render that’s blown, hollow or coming away
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

About our external mastic in Fairlie
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on concrete & block, brickwork movement joints and render & cladding joints, and the jobs we see most are sealant pulling away from one side of the joint and moss and dirt in joints with no sealant left.
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.
Each job carries a 12-month guarantee.

Questions from Fairlie
I let a flat near Fairlie station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Fairlie?
Yes, Fairlie is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
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.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin from the range available.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
How it works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around Fairlie depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Landlords, agents and businesses in Fairlie
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Deal with leaking gutters that soak the joints below
- Do not let climbing plants root in the sealant
- Wash walls gently around the sealant
- Make sure movement joints aren’t pointed over
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Walls and rooflines in Fairlie
Fairlie is within about 1 mile of 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. Fairlie 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.
Rented homes near Fairlie station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a place like Fairlie, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Surface by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Signs you need external mastic in Fairlie
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
- Failed seals between different materials
- Sealant that has lost its bond to the brick or render
Around Fairlie, as everywhere, external mastic is only as good as the preparation behind it.
