How we handle external mastic in Glamis
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We work on brickwork movement joints, joints between brick and frames and copings & trims, and common reasons people get in touch are joints where the bead has come unstuck and joints pointed up with cement by mistake.
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.
Big or small, it’s backed by our one-year guarantee.

What we’re called out for in Glamis
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Most people get in touch after spotting one of these:
- Gaps where render, brick and frames meet
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
In and around Glamis, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Whether the sealant suits the joint
- Whether they’re fully insured
- When the joint can take water or movement
- Whether they seal over old material or remove it
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In an older home around Glamis, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

Glamis buildings and the weather
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as St Fergus's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. For a place like Glamis, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive

Surface by surface
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.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
What we cannot put right
Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.

Glamis questions
Is external mastic in Glamis guaranteed?
All our work, in Glamis and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Glamis within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
How do I get a quote for external mastic in Glamis?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Act on the first splits you see
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
