- Water getting into walls through failed joints
How the job changes by surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
External mastic in Lossiemouth, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. We work on concrete & block, brickwork movement joints and render & cladding joints, and the jobs we see most are joints pointed up with cement by mistake and joints where the bead has come unstuck.
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 one-year guarantee comes as standard, so you’re covered after we’ve gone.

When it is not the sealant
In fairness, some problems need a different trade:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Do you need external mastic in Lossiemouth?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
Managing a site like Lossiemouth High School? Then its movement joints, gutters and trims need looking after like any other building’s.

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a place like Lossiemouth, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

FAQs for Lossiemouth
Do you cover smaller places like Lossiemouth?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is Lossiemouth in your area for external mastic?
Yes. We work across all of Scotland, and Lossiemouth is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Lossiemouth.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Ask before painting over external sealant
- Point out the joints to other trades
- Have failed joints looked at early
- Check external joints each spring
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Walls and rooflines in Lossiemouth
Lossiemouth 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’s 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 failed outside joints work against that.
Around Lossiemouth, as everywhere, external mastic is only as good as the preparation behind it.
