Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us

External mastic for homes and businesses in Carmichael
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. Common call-outs are for joints with sealant missing in places and joints pointed up with cement by mistake, across concrete & block, façade panels and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Carmichael depends on the weather. Tell us how to reach each wall, gutter and roofline.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
So the new joints stay in good condition:
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
- Walk round the building once a year and look at the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by walking round the building and agreeing the joints and the access.
- 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 items away from the joints we’re working on
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Carmichael questions
Is Carmichael in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Carmichael is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Carmichael?
Yes. Carmichael is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What is a movement joint?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
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.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.

External mastic in Carmichael: local notes
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near Carmichael Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
- Movement that’s more than a sealant joint can take
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- Façade panels
- Concrete & block
- Brickwork movement joints
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
Do you need external mastic in Carmichael?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Keep an eye out for any of the following:
- Rigid filler in a joint that should flex
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
Rented homes near Lanark station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether the sealant suits the joint
- What the cure time is
- Whether they’re fully insured
- How the surfaces are prepared before sealing
