External mastic in Kilkerran
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Common call-outs are for weathered mastic that no longer stretches and panel joints letting water in, on concrete & block, copings & trims and façade panels.
In and around a place like Kilkerran, 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.

Signs you need external mastic in Kilkerran
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Most people get in touch when they notice one of these:
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
- Failed seals between different materials
- Damp patches traced to an open external joint
If you live in an older home near Kilkerran Old Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before you book
- Whether you can choose the colour
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?

Why it’s worth doing now in Kilkerran
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.

Common questions in Kilkerran
Does the coastal weather in Kilkerran affect outside sealant?
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.

Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How long does external mastic take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer.

Kilkerran 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.
