What we’re called out for in North Kessock
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
- Panel joints letting water in
- Weathered mastic that no longer stretches
If you let a flat or house near Inverness station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in North Kessock, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on concrete & block, render & cladding joints and joints between brick and frames, and people most often call us about leaking joints around cladding and façade panels and rain getting behind render or cladding at a joint.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
All of our work is guaranteed for twelve months, in North Kessock and everywhere else we cover.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outside jobs in North Kessock need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Mention any parking rules near the property

North Kessock: your questions answered
Is North Kessock within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in North Kessock affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.

What the job involves on each surface
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 the movement is taken up.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
External mastic in North Kessock: local notes
North Kessock 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. North Kessock 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.
Schools such as Inverness High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Historic houses such as Old Allangrange House, about 2.2 miles north-west, show how far back building around North Kessock goes.

Why it’s worth doing now in North Kessock
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
