Advice
External mastic in Greenhill
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Typical jobs include leaking joints around cladding and façade panels and moss and dirt in joints with no sealant left, across brickwork movement joints, façade panels and render & cladding joints.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Greenhill, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Big or small, you get the same one-year guarantee in Greenhill and across Edinburgh.

How we quote for external mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Roughly how big the job is
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Clear growth from the base of walls and joints
- Keep movement joints as flexible joints, not mortar
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Why it’s worth doing now in Greenhill
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Walls and rooflines in Greenhill
Greenhill is within about 3 miles 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. 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.
Managing a site like Iain Tomlin School of Music? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Morningside United Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Haymarket station? Then split movement joints are easy to miss on a rental until damp shows inside.

Questions from Greenhill
Does the coastal weather in Greenhill affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
How is work on the outside of a tenement in Greenhill generally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Send us any details you have about the façade.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and helps it last.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
