External Mastic in Greenbank
External mastic across Greenbank and nearby, with old sealant always removed completely and a 12-month guarantee.
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
Common problems we fix in Greenbank
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we’re asked about most:
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
- Failed seals between different materials
Schools such as Firrhill High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Before booking anyone
- When the joint can take water or movement
- Whether the sealant suits the joint
- Whether they’re fully insured
- How long the guarantee is
External mastic in Greenbank, done properly
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 access is needed. If you are dealing with gaps where render, brick and frames meet and rain getting behind render or cladding at a joint, we can put it right, whatever the surface.
Gutters and downpipes on tall city tenements are a long way up, so a leaking joint can run down the stone for months before anyone notices. In Greenbank, access needs planning, and work on shared parts may need the other owners’ agreement.
Every job comes with our 12-month guarantee, wherever you are in Edinburgh.

Outside joints around Greenbank
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Your title deeds say which parts are shared. 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.
Historic houses such as Whitefoord House, about 3 miles north-east, show how far back building around Greenbank goes. Rented homes near Slateford station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Act on the first splits you see
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Inside a flat in Greenbank, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- 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.

Common questions in Greenbank
Do you work for landlords with property near Slateford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How do repairs to the shared parts of a tenement in Greenbank get organised?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you cover Greenbank?

Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What is a movement joint?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
