What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them

External mastic in Troqueer, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you are dealing with water getting into walls through failed joints and hard, crazed mastic that has stopped moving, we can put it right.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
You’re covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention any tricky access
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clear growth from the base of walls and joints
- Act on the first splits you see
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of 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 is not too deep.
External mastic in Troqueer: local notes
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For landlords with property near Dumfries station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Dumfries Academy, its movement joints, gutters and trims need looking after like any other building’s.

Troqueer: your questions answered
Is Troqueer in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Troqueer is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Troqueer?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you insured?
Yes, we are fully insured.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
What does external mastic cost?
It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. In a place like Troqueer, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we’re called out for in Troqueer
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The problems people generally mention when they call include:
- Panel joints letting water in
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
Homes close to Troqueer Parish Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
