External mastic in Millerston, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. We’re often asked to deal with rigid filler in a joint that should flex and gaps where render, brick and frames meet, on brickwork movement joints, joints between brick and frames and concrete & block.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. For a building in Millerston, access is planned first, and shared parts may need the other owners to agree.
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.

Signs you need external mastic in Millerston
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
These are the problems we are asked about most:
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
For landlords with property near Robroyston station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Honest limits
It helps to know what we can’t do too:
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
- Movement that is more than a sealant joint can take

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job normally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Millerston, 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 will 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- The size of the job
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
Photos by email are helpful but not essential. Please mention:
- The address or postcode of the job
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- A few photos by email, if you can
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.
Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant isn’t too deep.

Millerston questions
Do you work for landlords with property near Robroyston station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is Millerston in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Millerston is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. We will confirm how long when we quote.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Millerston buildings and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Historic houses like Provand's Lordship (about 3.2 miles south-west) are a reminder that the area around Millerston has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
