External Mastic in Corry
We cover Corry for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
Common problems we fix in Corry
Poor preparation causes many early failures: 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.
The problems people normally mention when they call include:
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
If you live in an older home near Broadford Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic for homes and businesses in Corry
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We are often asked to deal with rigid filler in a joint that should flex and weathered mastic that no longer stretches, across façade panels, render & cladding joints and joints between brick and frames.
External sealant needs dry surfaces, so outdoor work around Corry is planned around the weather. Tell us how to reach each wall, gutter and roofline.
All our work comes with our one-year guarantee, wherever you are in Highland.

When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:
- Damp that is not coming from the joint
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Common questions in Corry
Will you come out to Corry?
Yes, Corry is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Corry affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away and have them redone then.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How long does external mastic take?
A typical job takes anything from a few hours to several days, depending on the building, including the preparation. Your quote will say how long we expect yours to take.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. Around Corry, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in

Related advice
Walls and rooflines in Corry
Corry 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. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Around Corry, as everywhere, external mastic is only as good as the preparation behind it.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Wash walls gently around the sealant
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
