- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Old sealant gone brittle and cracked
The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Balliveolan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for 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.
How to prepare
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

External mastic for homes and businesses in Balliveolan
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We’re often asked to deal with hard, crazed mastic that has stopped moving and joints with sealant missing in places, on brickwork movement joints, copings & trims and façade panels.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Your questions about external mastic in Balliveolan
Is external mastic in a coastal place like Balliveolan any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you do external mastic in Balliveolan?
Yes. We work across all of Scotland, and Balliveolan is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Do you use backing rod?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Landlords, agents and businesses in Balliveolan
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
External mastic in Balliveolan: local notes
Balliveolan is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Whether the job is in Balliveolan itself or nearby, the right material for each joint matters as much as a neat finish. In and around Balliveolan, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Keeping the joints in good condition
So the new joints stay in good condition:
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we’ve said otherwise
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Quotes for external mastic in Balliveolan
Your quote is based on your job. We look at:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a place like Balliveolan, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What sealant work can’t fix
It helps to know what we cannot do too:
- Failed render or damaged cladding panels
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
What we seal
- Copings & trims
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
