Your questions about external mastic in Silverknowes
Do you work for landlords with property near South Gyle station?

How do repairs to the shared parts of a tenement in Silverknowes 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. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
External mastic for homes and businesses in Silverknowes
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. We work on concrete & block, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are joints where the bead has come unstuck and leaking joints around cladding and façade panels.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Silverknowes, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
You get a 12-month guarantee, the same in Silverknowes as everywhere else we work.

Why it’s worth doing now in Silverknowes
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. For landlords in Silverknowes, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.

What external mastic looks like in Silverknowes
Silverknowes 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. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. The title deeds set out which parts are common.
Rented homes near South Gyle station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Craigroyston Community High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St Columba's Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for a handful of joints, longer for a whole elevation. In a city area like Silverknowes, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- 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.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
What we seal
- Façade panels
- Concrete & block
