About our external mastic in Moredun
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Typical jobs include joints where the bead has come unstuck and brick movement joints where the sealant has split, across copings & trims, joints between brick and frames and concrete & block.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Moredun, those joints dry out over time and let water in behind the render or cladding.
Whatever the size of the job, it’s backed by our one-year guarantee.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How it works
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Moredun, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Tell us about any water getting in

How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- How much there is to do
- The type of sealant required
- How easy the joints are to reach
- The number of rooms or windows
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- How we’d reach the joints
- The rough size of the job
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. In a tenement flat in Moredun, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

What external mastic looks like in Moredun
Moredun is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Melville Castle (about 2 miles south-east) nearby, there’s older building stock in the area around Moredun as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Liberton High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Shawfair station, outside joints that have cracked can let damp into a rental, so check them between lets.

FAQs for Moredun
How do repairs to the shared parts of a tenement in Moredun get organised?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Does living near the coast affect external mastic in Moredun?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work in Moredun?
Yes. We work in Moredun, as part of our work across South East England, London and Scotland. For a quote, email us at info@mrmastic.co.uk.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Edinburgh.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
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 any work starts.
What we are called out for in Moredun
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
- Sealant that has lost its bond to the brick or render
If you live in an older home near Liberton Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
