About our external mastic in Achintee
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. Typical jobs include damp patches traced to an open external joint and sealant pulling away from one side of the joint, across concrete & block, copings & trims and façade panels.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Achintee: your questions answered
Is external mastic in a coastal place like Achintee any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Will you come out to Achintee?
Yes, Achintee is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
How much does external mastic cost in Achintee?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we have said otherwise
- Tell anyone working on the walls about the movement joints
- Never let anyone fill a movement joint with mortar
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

Signs you need external mastic in Achintee
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Any of these means the joints need attention:
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
Letting a property close to Strathcarron station? Then split movement joints are easy to miss on a rental until damp shows inside.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why it’s worth doing now in Achintee
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In an older home around Achintee, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Landlord and commercial work in Achintee
For anyone letting property in or around Achintee, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. 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. Outside jobs in Achintee need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Outside joints around Achintee
Achintee is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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.
For site and facilities teams at buildings such as Kirkton in Meikle Strath School, larger buildings have long runs of movement joint that eventually need resealing.
Achintee is in Highland. We provide external mastic to homes and businesses in Achintee and the surrounding area. Achintee is one of 253 towns and villages in Highland where we work for external mastic.
