Ardrishaig External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Ardrishaig. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
What happens on the day
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height

External mastic in Ardrishaig
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We are often asked to deal with failed seals between different materials and weeds or debris growing in open joints, on render & cladding joints, façade panels and copings & trims.
External sealant needs dry surfaces, so outdoor work around Ardrishaig is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Questions from Ardrishaig
Is Ardrishaig within the area you cover?
Yes, we do. 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.
Is external mastic in a coastal place like Ardrishaig any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
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.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
External mastic in Ardrishaig: local notes
Ardrishaig 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Lochgilphead High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Around Ardrishaig, as everywhere, external mastic is only as good as the preparation behind it.
Ardrishaig is about 27 miles west of Greenock, in Argyll and Bute. Every kind of property in Ardrishaig is covered for external mastic, old or new, large or small. The work is guaranteed for a year. Ardrishaig is one of 118 places in Argyll and Bute where we work for external mastic. Glasgow is on our list too, about 47 miles from Ardrishaig.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the cost of external mastic
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- The number and length of the joints
- Access and height
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Photos by email, if that is easy
- Any previous sealing or DIY work
- Roughly how big the job is
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why it’s worth doing now in Ardrishaig
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
