Glenbrook External Mastic
Problem with your movement joints in Glenbrook? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
When something else is needed
In fairness, there are a few things sealant will not fix:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.
Joints and surfaces we work on
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
- Façade panels
- Copings & trims
- Render & cladding joints
About our external mastic in Glenbrook
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on render & cladding joints, copings & trims and joints between brick and frames, and people most often call us about cracked joints where brick meets render or frames and brick movement joints where the sealant has split.
External sealant needs dry surfaces, so outdoor work around Glenbrook is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Your questions about external mastic in Glenbrook
Is Glenbrook within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Curriehill station. Can you help?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins, matched as closely as the range allows.
Are you fully insured?
Yes. We’re fully insured.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How much does external mastic cost in Glenbrook?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
- Wash walls gently around the sealant
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Landlords, agents and businesses in Glenbrook
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes 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.
External mastic in Glenbrook: local notes
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Curriehill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Balerno Community High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What’s near Glenbrook
Locally, jobs take us to homes and businesses close to Malleny Park and the streets around them. The closest station to Glenbrook is Curriehill station, roughly 2.4 miles north-east of the centre. A little further out are Bavelaw Castle (2.3 miles south-east) and Linburn Centre (2.2 miles north-west). Open spaces near Glenbrook include Black Hill.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Around Glenbrook, water from a failed joint in an older stone home can soak into timber and plaster.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

What we are called out for in Glenbrook
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Look out for any of the following:
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
In the older streets around Balerno Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. For a place like Glenbrook, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
