Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
External mastic for homes and businesses in Tayvallich
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with movement joints with cracked, split or missing sealant and joints pointed up with cement by mistake, we can put it right, on concrete & block, copings & trims and joints between brick and frames alike.
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.
You are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Your questions about external mastic in Tayvallich
Does the coastal weather in Tayvallich affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Tayvallich in your area for external mastic?
Yes, Tayvallich is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
When will the joints need doing again?
There’s no fixed answer: 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.
What is backing rod for?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we’ll say how long yours will take.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
External mastic in Tayvallich: local notes
Tayvallich is within about 1 mile 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. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
In the older streets around Tayvallich Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Around Tayvallich, as everywhere, external mastic is only as good as the preparation behind it.
Tayvallich is about 33 miles west of Greenock, in Argyll and Bute. We provide external mastic to homes and businesses in Tayvallich and the surrounding area. 118 places in Argyll and Bute are on our list, from the larger towns to small villages.

Work in PA31 works the same way as everywhere else we cover. If you’re just outside Tayvallich, we cover Cairnbaan (6 miles north-east), Ardrishaig (7 miles east), Lochgilphead (7 miles east), Ceann Loch Gilb (8 miles east) and Bridgend (8 miles north-east). If you’re somewhere remote, a little more planning is needed.

Keeping the joints in good condition
Aftercare is simple:
- Clear growth from the base of walls and joints
- Keep movement joints as flexible joints, not mortar
- Look over the joints every year, ideally after winter
- Act on the first splits you see
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
What we do, step by step
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation. Around Tayvallich, distance and access matter more than parking. 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.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare

Related advice
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
