FAQs for Kingsknowe
Can you do external mastic in Kingsknowe?
Yes, Kingsknowe is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Kingsknowe station?
Yes, landlords and agents are among the people we work for. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
What is backing rod for?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
About our external mastic in Kingsknowe
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We are often asked to deal with joints pointed up with cement by mistake and sealant pulling away from one side of the joint, on façade panels, render & cladding joints and joints between brick and frames.
Gutters and downpipes on tall city tenements are a long way up, and a slow drip can stain and soak the stone for a long time before it’s spotted. For a building in Kingsknowe, access is planned first, and shared parts may need the other owners to agree.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. 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.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.

Common problems we fix in Kingsknowe
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
Managing a site like Merchiston Castle School? Then larger buildings have long runs of movement joint that eventually need resealing.

Walls and rooflines in Kingsknowe
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.

How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We also work for property managers and facilities teams in Kingsknowe and across Edinburgh. We can quote a run of properties together, and we are fully insured for the work.
