Granton: your questions answered
How do repairs to the shared parts of a tenement in Granton get organised?
The owners of the flats generally 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.
Do you work for landlords with property near Haymarket station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we’ll say how long yours will take.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render. Exterior sealants come in a good range of colours.
External mastic in Granton, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We’re often asked to deal with cracked joints where brick meets render or frames and water getting into walls through failed joints, on joints between brick and frames, concrete & block and render & cladding joints.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Granton, work on shared parts of a tenement is usually agreed between owners, often with a factor arranging it.

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. In a tenement flat in Granton, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a tenement in Granton, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Have failed joints looked at early
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Keep water from gutters off the wall
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
When to call us in Granton
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Most people get in touch when they notice something like this:
- Weeds or debris growing in open joints
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
In the older streets around Granton Congregational Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Walls and rooflines in Granton
Granton is within about 1 mile of 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. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Your title deeds say which parts are shared.
If you look after a building such as Ainslie Park High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Haymarket station, outside joints that have cracked can let damp into a rental, so check them between lets.
