External mastic in Drimlabarra, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. If you have joints with sealant missing in places and failed sealant between panels on a façade, we can put it right.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
Big or small, you get the same one-year guarantee in Drimlabarra and across North Ayrshire.

How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. Outdoor work around Drimlabarra depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit

Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. In an older home around Drimlabarra, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.

External mastic in Drimlabarra: local notes
Drimlabarra 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
In and around Drimlabarra, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Questions from Drimlabarra
Is Drimlabarra within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Does the coastal weather in Drimlabarra affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you work for letting agents?
Yes, often. Several properties can be quoted together.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. We will reseal it with a flexible sealant.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
When to call us in Drimlabarra
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Keep an eye out for these signs:
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
For an older house near a landmark such as Church Of Scotland, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What the job involves on each surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one.
