External mastic for homes and businesses in Armadale
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on joints between brick and frames, brickwork movement joints and copings & trims, and common reasons people get in touch are joints with sealant missing in places and leaking joints around cladding and façade panels.
External sealant needs dry surfaces, so outdoor work around Armadale is planned around the weather. Let us know about access to every wall and roofline.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access. Around Armadale, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

Should I try it myself first?
If you do try it yourself, take your time over the 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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Outside joints around Armadale
Armadale is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Armadale 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.
Letting a property close to Mallaig station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In and around Armadale, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Armadale (Gaelic: Armadail) is in Highland. Whether you’re in the middle of Armadale or further out, external mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Armadale is one of 253 towns and villages in Highland where we work for external mastic.

Near you in Armadale
Armadale’s nearest station is Mallaig station, roughly 4.9 miles south-east of the centre. A little further out are Museum of the Isles (within half a mile north) and Armadale Castle (0.5 miles north). Not far away are Loch Ic Iain and Sgùrr nan Caorach.
Why it’s worth doing now in Armadale
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Aftercare tips
A little care helps the new joints last. Our advice:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Act on the first splits you see
- Show decorators and builders where the movement joints are
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.

Different surfaces, different methods
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
