External mastic for homes and businesses in Goldenacre
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We’re often asked to deal with cracked joints where brick meets render or frames and rain getting behind render or cladding at a joint, across brickwork movement joints, concrete & block and copings & trims.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Goldenacre, those joints dry out over time and let water in behind the render or cladding.
Big or small, it’s backed by our 12-month guarantee.

Surface by surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
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.
Quotes for external mastic in Goldenacre
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- The old material and how stubborn it is
- How many areas need sealing
- When we can work, for business premises
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- The type of property
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
When something else is needed
It helps to know what we can’t do too:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.

Why deal with it now?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. Private landlords in Goldenacre must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why book with us
- An ARBOMaster approved applicator
- We are fully insured
- We never seal over old sealant
- We leave the area clean and tidy

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Outside joints around Goldenacre
Goldenacre is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Edinburgh’s Old and New Towns 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.
Rented homes near Edinburgh Waverley station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near St Serf's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Trinity Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. For a tenement in Goldenacre, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Common questions in Goldenacre
Who arranges sealant work on the shared parts of a tenement in Goldenacre?
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.
Do you work for landlords with property near Edinburgh Waverley station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
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. It’s closed with backing rod and a flexible sealant.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
