External mastic for homes and businesses in Baile a' Mhanaich
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 have gaps where render, brick and frames meet and panel joints letting water in, we can put it right.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.

Common questions in Baile a' Mhanaich
Will you come out to Baile a' Mhanaich?
Yes, Baile a' Mhanaich is covered. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect external mastic in Baile a' Mhanaich?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before work begins from the range available.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that is more than a sealant joint can take
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Baile a' Mhanaich buildings and the weather
Baile a' Mhanaich is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
For jobs in and around Baile a' Mhanaich, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job normally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Outdoor work around Baile a' Mhanaich depends on the weather, as sealant needs a dry surface, 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

Why act early in Baile a' Mhanaich
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. In a place like Baile a' Mhanaich, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before any work starts.
