External mastic in Corpach
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. We are often asked to deal with plants rooting in failed movement joints and joints with sealant missing in places, across brickwork movement joints, joints between brick and frames and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Corpach depends on the weather. Let us know about access to every wall and roofline.
Each job carries a 12-month guarantee, large or small.

What else we do in Corpach
Common questions in Corpach
Do you cover smaller places like Corpach?
Yes, Corpach is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Corpach station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
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 the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How the visit works
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Somewhere like Corpach may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
How to get a quote

Advice
What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Why it’s worth doing now in Corpach
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. 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.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Render that’s blown, hollow or coming away
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Corpach buildings and the weather
Corpach is close to 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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Corpach station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Common problems we fix in Corpach
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Look out for any of the following:
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
For site and facilities teams at buildings such as Lochaber High School, larger buildings have long runs of movement joint that eventually need resealing.
