What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes a few hours for a handful of joints, longer for a whole elevation. Around Swinton, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- 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.
Before we arrive
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints

External mastic in Swinton, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We work on façade panels, joints between brick and frames and concrete & block, and common reasons people get in touch are weeds or debris growing in open joints and movement joints with cracked, split or missing sealant.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Swinton: your questions answered
Is Swinton within the area you cover?
Yes. Swinton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Easterhouse station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Where do you work from?
We work from Crawley. Our applicators cover Swinton, along with the rest of our area.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Common problems we fix in Swinton
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
People generally contact us after spotting something like this:
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
Letting a property close to Easterhouse station? Then split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- When the joint can take water or movement
- Whether you can choose the colour
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
Aftercare tips
To keep the joints looking good and working properly:
- Check external joints each spring
- Make sure movement joints are not pointed over
- Keep water from gutters off the wall
- Avoid pressure-washing directly into sealant joints
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.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
External mastic in Swinton: local notes
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that won’t mark it. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you live in an older home near St John's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as St. Leonard's Secondary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the job changes by surface
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
Why it’s worth doing now in Swinton
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t 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.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
