External Mastic in Baberton
Problem with your movement joints in Baberton? We cut out the old, prepare the joints and apply the right sealant.
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
External mastic for homes and businesses in Baberton
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. We’re often asked to deal with sealant pulling away from one side of the joint and joints pointed up with cement by mistake, on concrete & block, render & cladding joints and brickwork movement joints.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Baberton, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Big or small, you get the same one-year guarantee.

Honest limits
In fairness, there are a few things sealant will not fix:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall

The process
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes a few hours to a few days, depending on the length of joint and the access. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Baberton, tell us the floor, how the door entry system works and where we can park nearby.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

External mastic in Baberton: local notes
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. 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 landlords with property near Wester Hailes station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Wester Hailes Baptist Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Scottish rain finds any gap around a frame or wall joint, and in Baberton, damp can spread through stone and plaster before anyone sees it.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Tell anyone working on the walls about the movement joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Baberton questions
Do you cover Baberton for external mastic?
Yes. We work across all of Scotland, and Baberton is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Baberton?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Windows often belong to the individual flat, but it’s worth checking your deeds.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams. We can quote a run of properties together.
Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
