- Weathered mastic that no longer stretches
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
External mastic in Seafield, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you are dealing with weeds or debris growing in open joints and joints pointed up with cement by mistake, we can put it right, on copings & trims, brickwork movement joints and façade panels alike.
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 Seafield, access is planned first, and shared parts may need the other owners to agree.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Seafield, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- 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.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Advice
Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Seafield buildings and the weather
Seafield is close to 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. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
For site and facilities teams at buildings such as Leith Academy, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Edinburgh Waverley station, outside joints that have cracked can let damp into a rental, so check them between lets.
Seafield is about 1 mile north-east of Lochend, in Edinburgh. Anywhere in EH6, we can carry out external mastic at your property. Across Edinburgh, we cover 175 places, and Seafield is one of them.
Work in EH6, EH7 and EH15 works the same way as everywhere else we cover. You’ll find streets such as Blackie Road, Seafield Road and Restalrig Road. Neighbouring places we cover for external mastic include Restalrig (1 mile south-west), Craigentinny (1 mile south-east), Lochend (1 mile south-west), Piershill (1 mile south) and Jock's Lodge (1 mile south).

What’s near Seafield
We work in homes and buildings around Public House, Portobello Library and Lochend Park, among other places. The nearest railway station is Edinburgh Waverley station, roughly 2.2 miles south-west. Well-known places in the area include Eastern General Hospital (within half a mile west) and Ocean Terminal (1.5 miles north-west). For a walk, there’s Whinny Hill and The New Leaf Co-op.
What we’re called out for in Seafield
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
The problems people normally mention when they call include:
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
In the older streets around Restalrig Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a tenement flat in Seafield, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Act on the first splits you see
- Check external joints each spring
- Avoid pressure-washing directly into sealant joints
- Check the sealant is paintable before painting near it
Do not 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. That can lead to damp patches, staining and frost damage.
Seafield: your questions answered
Do you work for landlords with property near Edinburgh Waverley station?
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 quote.
Who arranges sealant work on the shared parts of a tenement in Seafield?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t.
Do you work in Seafield?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall. If it has already been filled, we can usually cut it out and reseal it.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
