External & façade joints in Carrick Knowe, Edinburgh
External mastic for Carrick Knowe and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Movement joints with cracked, split or missing sealant
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
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.
External mastic for homes and businesses in Carrick Knowe
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have brick movement joints where the sealant has split and joints pointed up with cement by mistake, we can help, whatever the surface.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Carrick Knowe, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the quote in Carrick Knowe
You will get a clear quote before any work starts. It takes into account:
- The number of rooms or windows
- Mould in or behind the old joints
- The old material and how stubborn it is
- The amount of work
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, and we will explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Photos by email, if that is easy
- What’s wrong with the joints now
- The type of property
- If someone has resealed it before
If you are in Carrick Knowe and need external mastic, send an email to info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What we can’t put right
We’ll always be straight with you, so here’s what sealant cannot fix:

- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.

What else we do in Carrick Knowe
How to look after the new joints
After the cure time, these simple habits help:
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Carrick Knowe questions
Can you help a landlord with a rental near South Gyle station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Does the coastal weather in Carrick Knowe affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
Do you work in Carrick Knowe?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Carrick Knowe.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Outside joints around Carrick Knowe
Carrick Knowe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around St Anne's Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to South Gyle station? Then split movement joints are easy to miss on a rental until damp shows inside.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Carrick Knowe, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs 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
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Related advice
What we’re called out for in Carrick Knowe
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Common reasons people contact us are:
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
Managing a site like Scotus Academy? Then larger buildings have long runs of movement joint that eventually need resealing.
