DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
External mastic in Craignure, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. Common call-outs are for rain getting behind render or cladding at a joint and cracked joints where brick meets render or frames, across render & cladding joints, joints between brick and frames and façade panels.
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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What external mastic looks like in Craignure
Craignure 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. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
In the older streets around Torosay Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Craignure
Does living near the coast affect external mastic in Craignure?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will you come out to Craignure?
Yes, Craignure is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.
Do you have insurance?
Yes. Mr Mastic is fully insured.
How much does external mastic cost in Craignure?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Craignure.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In an older home around Craignure, damp from a failed joint can get into timber and plaster.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Façade panels
- Concrete & block
Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Common problems we fix in Craignure
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:
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
In and around Craignure, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. Outside jobs in Craignure need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure movement joints aren’t pointed over
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Check external joints each spring
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
