External Mastic in Blairninich
Specialist external mastic for Blairninich: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
How we handle external mastic in Blairninich
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you have joints with sealant missing in places and hard, crazed mastic that has stopped moving, we can help.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Blairninich: your questions answered
I let a flat near Dingwall station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Blairninich?
Yes, Blairninich is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
External mastic in Blairninich: local notes
Blairninich is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. 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.
Letting a property close to Dingwall station? Then split movement joints are easy to miss on a rental until damp shows inside.

What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outdoor work around Blairninich depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive

Advice
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. 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.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why Blairninich clients choose us
- We agree the colour with you first
- We are fully insured
- More than 20 years in sealant work
- Sealant colour chosen to suit

Signs you need external mastic in Blairninich
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
In and around Blairninich, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Whether the sealant suits the joint
- What happens if the job turns out different
- Is the old sealant removed completely?
- Is VAT in the price?

How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
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.
