About our external mastic in Dalmally
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you are dealing with water getting into walls through failed joints and failed seals between different materials, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Dalmally depends on the weather. Let us know about access to every wall and roofline.
The work is covered for a year after we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Common problems we fix in Dalmally
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Keep an eye out for any of the following:
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
If you let a flat or house near Dalmally station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- Whether VAT is included
- What happens if the job turns out different
- Are they insured?
- When the joint can take water or movement
External mastic in Dalmally: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
If you live in an older home near Glenorchy Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What else we do in Dalmally
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the joints every year, ideally after winter
- Make sure movement joints are not pointed over
- Leave the joints unpainted unless we’ve said otherwise
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
When something else is needed
A few problems are outside what sealant work can do:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

Questions from Dalmally
Can you help a landlord with a rental near Dalmally station?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you cover Dalmally for external mastic?
Yes, Dalmally is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Clear the area around the work

Quotes for external mastic in Dalmally
The price is agreed before any work begins. It’s based on:
- Any working-time requirements on site
- Mould in or behind the old joints
- Access and height
- The amount of work
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Asking for a quote
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- Where the property is
- Roughly how big the job is
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job and send pictures if you have them.
Why it’s worth doing now in Dalmally
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.
