About our external mastic in Vassa
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on render & cladding joints, copings & trims and brickwork movement joints, and the jobs we see most are water getting into walls through failed joints and plants rooting in failed movement joints.
Outside joints can only be sealed when they’re dry, so work in Vassa depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Signs you need external mastic in Vassa
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
These are the problems we are asked about most:
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
Whether the job is in Vassa itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- When the joint can take water or movement
- Who does the work, and how experienced they are
- What guarantee comes with the work
- How hidden problems are handled
What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. For a place like Vassa, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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
- Let us know about parking restrictions
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Why it’s worth doing now in Vassa
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. In a place like Vassa, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why choose Mr Mastic in Vassa

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What sealant work cannot fix
To be straight with you, there are a few things sealant will not fix:
- Walls that need new movement joints cut into them
- Damp that isn’t coming from the joint
- Render that’s blown, hollow or coming away
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

What external mastic looks like in Vassa
Vassa 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Around Vassa, as everywhere, external mastic is only as good as the preparation behind it.

Your questions about external mastic in Vassa
Is Vassa in your area for external mastic?
Yes. We work across all of Scotland, and Vassa is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Vassa?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will it make 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.
