Oxgangs External Mastic
Our applicators work in Oxgangs on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that is more than a sealant joint can take
- Walls that need new movement joints cut into them
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Copings & trims

How we handle external mastic in Oxgangs
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Common call-outs are for damp patches traced to an open external joint and failed seals between different materials, across façade panels, joints between brick and frames and brickwork movement joints.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Oxgangs, repairs to shared parts are generally agreed between the owners, often through a property factor.
You get a one-year guarantee, the same in Oxgangs as everywhere else we work.

Aftercare tips
To keep the joints looking good and working properly:
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Walls and rooflines in Oxgangs
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Historic houses like Whitefoord House (about 3.5 miles north-east) are a reminder that the area around Oxgangs has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Firrhill High School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Slateford station, split movement joints are easy to miss on a rental until damp shows inside. Whitefoord House, about 3.5 miles north-east, is one of the historic houses in the wider area around Oxgangs, and older homes nearby need a sealant that suits their walls.

What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Oxgangs, damp can travel a long way before it shows.

Oxgangs: your questions answered
How is work on the outside of a tenement in Oxgangs normally arranged?
It generally 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 don’t.
I let a flat near Slateford station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How much does external mastic cost in Oxgangs?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint doesn’t draw the eye.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
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.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Inside a flat in Oxgangs, 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.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
Getting a quote

What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
