Why it’s worth doing now in Kilmaluag
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a place like Kilmaluag, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

External mastic in Kilmaluag, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We work on brickwork movement joints, joints between brick and frames and copings & trims, and the jobs we see most are old sealant gone brittle and cracked and movement joints filled with mortar instead of sealant.
In and around a place like Kilmaluag, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
Big or small, you get the same 12-month guarantee in Kilmaluag and across Highland.

Questions from Kilmaluag
Is Kilmaluag in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Kilmaluag is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Does the coastal weather in Kilmaluag 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. Walls facing the sea are generally the first to need attention.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How long does external mastic last?
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.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. If it has already been filled, we can normally cut it out and reseal it.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.
What we seal
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
- Façade panels
- Render & cladding joints
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
- Look over the joints every year, ideally after winter
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Signs you need external mastic in Kilmaluag
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
The most common problems we see are:
- Failed seals between different materials
- Failed sealant between panels on a façade
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
For jobs in and around Kilmaluag, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- How long to leave it before use
- Are they insured?
- What guarantee comes with the work
- How the joint is cleaned and prepared

Walls and rooflines in Kilmaluag
Kilmaluag is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In and around Kilmaluag, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
