How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
External mastic in Slateford
On houses, flats and commercial buildings across Slateford, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you’re dealing with water getting into walls through failed joints and plants rooting in failed movement joints, we can help.
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. For a building in Slateford, access is planned first, and shared parts may need the other owners to agree.
All our work is covered by a 12-month guarantee, wherever you are in Edinburgh.

Signs you need external mastic in Slateford
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and make things worse.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
Rented homes near Slateford station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Slateford questions
Is Slateford in your area for external mastic?
Yes, Slateford is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
How do repairs to the shared parts of a tenement in Slateford get organised?
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 do not.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. Wind-driven rain gets into any failed joint on the outside of a city building, and in Slateford, damp can spread through stone and plaster before anyone sees it.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
Why us?
- More than 20 years in sealant work

What external mastic looks like in Slateford
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as St. Cuthbert's Catholic Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Craiglockhart Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
- Check external joints each spring
- Leave the joints unpainted unless we’ve said otherwise
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
The process
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Parking in city streets around Slateford can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- First, the joints are inspected and the access agreed.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
