Advice
How we handle external mastic in Claddach Kirkibost
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. We work on concrete & block, copings & trims and façade panels, and the jobs we see most are water getting into walls through failed joints and failed seals between different materials.
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.
You get a one-year guarantee, the same in Claddach Kirkibost as everywhere else we work.

Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. In an older home around Claddach Kirkibost, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- We never seal over old sealant
- Neat joints and a tidy finish
- Homes, businesses and hotels
- Colour picked to suit the job
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Point out the joints to other trades
- Do not let climbing plants root in the sealant
- Have failed joints looked at early
- Make sure movement joints aren’t pointed over
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Outside joints around Claddach Kirkibost
Claddach Kirkibost 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. Island weather, with its wind and salt spray, is tough on movement joints and outside wall joints.
In and around Claddach Kirkibost, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Claddach Kirkibost: your questions answered
Do you cover Claddach Kirkibost for external mastic?
Yes. We work across all of Scotland, and Claddach Kirkibost is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Does the coastal weather in Claddach Kirkibost affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
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.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What we are called out for in Claddach Kirkibost
UV, rain and frost all age exterior sealant. 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 any of the following:
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
For jobs in and around Claddach Kirkibost, choosing the right material for each joint is as important as a tidy finish.
