Outside joints around Borestone
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. 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.
In and around Borestone, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

External mastic in Borestone, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We’re often asked to deal with sealant that has lost its bond to the brick or render and plants rooting in failed movement joints, on copings & trims, façade panels and joints between brick and frames.
In and around a place like Borestone, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a place like Borestone, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Move anything stored near the joints

Advice
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that is not coming from the joint
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on
- Copings & trims
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check external joints each spring
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Questions from Borestone
Can you do external mastic in Borestone?
Yes. We work across all of Scotland, and Borestone is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Is Borestone within the area you cover?
Yes. Borestone is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the building, including the preparation. We’ll confirm how long when we quote.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

What we are called out for in Borestone
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
It’s worth asking for a quote if you see:
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Panel joints letting water in
- Brick movement joints where the sealant has split
Rented homes near Stirling station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
