What we do, step by step

Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.

Advice
External mastic in Lochearnhead, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on façade panels, concrete & block and brickwork movement joints, and people most often call us about joints where the bead has come unstuck and leaking joints around cladding and façade panels.
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, it’s backed by our one-year guarantee in Lochearnhead and across Stirling.

Quotes for external mastic in Lochearnhead
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- Any working-time requirements on site
- The size of the job
- Access and height
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- Photos by email, if that is easy
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. In an older home around Lochearnhead, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

What external mastic looks like in Lochearnhead
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you live in an older home near St Angus Episcopal Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. In and around Lochearnhead, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Walk round the building once a year and look at the joints
- Avoid pressure-washing directly into sealant joints
- Get split or bare joints resealed while the damage is small
- Fix overflowing gutters above sealed joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Common questions in Lochearnhead
Is there a guarantee on external mastic in Lochearnhead?
All our work, in Lochearnhead and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Lochearnhead?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
How long does external mastic take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We’ll confirm how long when we quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
