Common questions in Inveraray
Does the coastal weather in Inveraray affect outside sealant?
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.
Can you do external mastic in Inveraray?
Yes, Inveraray is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
How long does external mastic last?
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 12-month guarantee.
How long will you be here?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How we handle external mastic in Inveraray
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have rigid filler in a joint that should flex and sealant that has lost its bond to the brick or render, we can put it right, on render & cladding joints, concrete & block and joints between brick and frames alike.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Big or small, you get the same 12-month guarantee in Inveraray and across Argyll and Bute.

How to look after the new joints
To keep the joints looking good and working properly:
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Check external joints each spring
- Deal with leaking gutters that soak the joints below
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. 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. Somewhere like Inveraray may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

Advice
Why it’s worth doing now in Inveraray
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a place like Inveraray, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. 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.

Common problems we fix in Inveraray
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
People usually contact us when they notice one of these:
- Damp patches traced to an open external joint
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
Around Inveraray, as everywhere, external mastic is only as good as the preparation behind it.

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 call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What affects the quote in Inveraray
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- The number and length of the joints
- The number of rooms or windows
- The type of sealant required
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- Where the property is
Every job is quoted individually. Simply email us at info@mrmastic.co.uk and describe the job, and pictures are welcome.

What else we do in Inveraray
Inveraray buildings and the weather
Inveraray is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Homes close to Inveraray Parish Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
