- The product the joint needs
- Whether there’s mould to deal with

How we handle external mastic in Jackton
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. We work on joints between brick and frames, render & cladding joints and façade panels, and people most often call us about joints pointed up with cement by mistake and failed sealant between panels on a façade.
Outside joints can only be sealed when they’re dry, so work in Jackton depends on the weather. Let us know about access to every wall and roofline.
All our work comes with a one-year guarantee, wherever you are in East Renfrewshire.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Outside jobs in Jackton need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires 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
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Walls and rooflines in Jackton
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we’ll tell you how long to expect.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What we can’t put right
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Concrete & block
- Façade panels
- Render & cladding joints
Do you need external mastic in Jackton?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
People normally contact us when they notice one of these:
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
- Weeds or debris growing in open joints
Managing a site like Duncanrig Secondary School? Then its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book

- What happens if the job turns out different
- What guarantee comes with the work

Why it’s worth doing now in Jackton
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
