External & façade joints in Strathyre, Stirling
Movement joints in Strathyre need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
External mastic in Strathyre, done properly
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 work on joints between brick and frames, copings & trims and façade panels, and people most often call us about movement joints with cracked, split or missing sealant and failed seals between different materials.
External sealant needs dry surfaces, so outdoor work around Strathyre is planned around the weather. Let us know about access to every wall and roofline.
There’s a 12-month guarantee on every job, whatever its size.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Strathyre may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Outside joints around Strathyre
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Strathyre, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Strathyre is about 21 miles north-west of Stirling, in Stirling.

What happens if it’s left?
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Strathyre, water from a failed joint in an older stone home can soak into timber and plaster.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Questions from Strathyre
Do you cover Strathyre for external mastic?
Yes, Strathyre is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
What guarantee comes with external mastic in Strathyre?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
How do I get a quote for external mastic in Strathyre?
Size, access and the old material all affect the cost. Call for a quick quote.
What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much there is to do
- Working hours on commercial sites
- The old material and how stubborn it is
- How easy the joints are to reach
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Roughly how big the job is
- Pictures of the joints, sent by email
For external mastic in Strathyre, send an email to info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
Common problems we fix in Strathyre
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Most people get in touch after spotting something like this:
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Joints with sealant missing in places
Whether the job is in Strathyre itself or nearby, the right material for each joint matters as much as a neat finish.
What to look for in a quote
- Is VAT in the price?
- What product goes in the joint
- Whether they’re fully insured
- The length of the guarantee
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Show decorators and builders where the movement joints are
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
