External & façade joints in Greosabhagh, Na h-Eileanan Siar
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Greosabhagh and across Na h-Eileanan Siar. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
Looking after it afterwards
To keep the joints looking good and working properly:
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Tell anyone working on the walls about the movement joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
How we handle external mastic in Greosabhagh
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We work on copings & trims, joints between brick and frames and façade panels, and people most often call us about old sealant gone brittle and cracked and failed sealant between panels on a façade.
External sealant needs dry surfaces, so outdoor work around Greosabhagh is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We stand behind the work with a one-year guarantee.

How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Outside jobs in Greosabhagh need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Common problems we fix in Greosabhagh
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Common reasons people contact us are:
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
For jobs in and around Greosabhagh, choosing the right material for each joint is as important as a tidy finish.

What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
FAQs for Greosabhagh
Is external mastic in a coastal place like Greosabhagh any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Greosabhagh in your area for external mastic?
Yes, Greosabhagh is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Greosabhagh.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Greosabhagh buildings and the weather
Greosabhagh is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Island weather, with its wind and salt spray, is tough on movement joints and outside wall joints.
Around Greosabhagh, as everywhere, external mastic is only as good as the preparation behind it.
Greosabhagh is in Na h-Eileanan Siar. Greosabhagh gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Our Na h-Eileanan Siar coverage runs to 87 places, Greosabhagh among them.

What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
