External mastic in Port Elphinstone: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
For an older house near a landmark such as St Mary's Episcopal Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Inverurie station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Inverurie Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

About our external mastic in Port Elphinstone
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have joints with sealant missing in places and joints pointed up with cement by mistake, we can help.
External sealant needs dry surfaces, so outdoor work around Port Elphinstone is planned around the weather. Let us know about access to every wall and roofline.
All of our work is guaranteed for twelve months, in Port Elphinstone and everywhere else we cover.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building. Outside jobs in Port Elphinstone 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.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
Getting a quote
Getting a quote is simple: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand.
Advice
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that’s blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Where we work in Port Elphinstone
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Copings & trims
- Concrete & block
- Joints between brick and frames
What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Landlord and commercial work in Port Elphinstone
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Port Elphinstone questions
I let a flat near Inverurie station. Can you help?
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’ll send you a clear quote.
Will you come out to Port Elphinstone?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What’s an expansion joint in brickwork?
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.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin from the range available.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Aftercare tips
After the cure time, these simple habits help:
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Clear growth from the base of walls and joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
