The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a place like Dulnain Bridge, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

About our external mastic in Dulnain Bridge
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We work on copings & trims, façade panels and joints between brick and frames, and common reasons people get in touch are weathered mastic that no longer stretches and leaking joints around cladding and façade panels.
In and around a place like Dulnain Bridge, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
All of our work is guaranteed for twelve months.

Your questions about external mastic in Dulnain Bridge
Do you cover Dulnain Bridge for external mastic?
Yes. We work across all of Scotland, and Dulnain Bridge is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
What guarantee comes with external mastic in Dulnain Bridge?
All our work, in Dulnain Bridge and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
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.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Landlords, agents and businesses in Dulnain Bridge
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.

Why act early in Dulnain Bridge
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Common problems we fix in Dulnain Bridge
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Keep an eye out for these signs:
- Joints where the bead has come unstuck
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
For jobs in and around Dulnain Bridge, choosing the right material for each joint is as important as a tidy finish.

External mastic in Dulnain Bridge: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
