Liberton External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Liberton. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Water getting into walls through failed joints
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
How we handle external mastic in Liberton
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. If you have sealant pulling away from one side of the joint and weathered mastic that no longer stretches, we can help, whatever the surface.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Liberton, work on shared parts of a tenement is usually agreed between owners, often with a factor arranging it.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.

What else we do in Liberton
What the job involves on each surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.
What affects the cost of external mastic
You’ll get a clear quote before any work starts. It’s based on:
- Access and height
- The old material and how stubborn it is
- Any mould that needs treating
- Any working-time requirements on site
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- The address or postcode of the job
- The type of property
- Any access issues, like height or stairs

Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

External mastic in Liberton: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. With historic houses such as Whitefoord House (about 2.7 miles north) nearby, there’s older building stock in the area around Liberton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Liberton High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Shawfair station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Liberton is about 3 miles south-east of Edinburgh, in Edinburgh.

Liberton: your questions answered
Is Liberton in your area for external mastic?
Yes. We work across all of Scotland, and Liberton is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Liberton?
It normally 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.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Edinburgh.
Is there a guarantee?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access from start to finish. Parking in city streets around Liberton can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit

Advice
What we’re called out for in Liberton
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Most people get in touch when they notice one of these:
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
In the older streets around Liberton Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- Is VAT in the price?
- The length of the guarantee
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Don’t let climbing plants root in the sealant
- Look over the joints every year, ideally after winter
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
