External mastic for homes and businesses in Gorthleck
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. We work on façade panels, render & cladding joints and brickwork movement joints, and people most often call us about weathered mastic that no longer stretches and rigid filler in a joint that should flex.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
All of our work is guaranteed for twelve months.

When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Render that is blown, hollow or coming away
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.

Outside joints around Gorthleck
With historic houses such as Boleskine House (about 2.1 miles north-west) nearby, there’s older building stock in the area around Gorthleck as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Boleskine House, about 2.1 miles north-west, is one of the historic houses in the wider area around Gorthleck, and older homes nearby need a sealant that suits their walls.

How the visit works
The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Outdoor work around Gorthleck depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- Which sealant suits the joint
- Working hours on commercial sites
- The number and length of the joints
No two jobs are quite the same, 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.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What’s wrong with the joints now
- Any access issues, like height or stairs
- The rough size of the job
- A few photos by email, if you can
There’s no standard price list. Instead, we give you a clear quote for your job. To get started, email us at info@mrmastic.co.uk.
Questions from Gorthleck
Do you cover smaller places like Gorthleck?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with external mastic in Gorthleck?
All our work, in Gorthleck and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Why act early in Gorthleck
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like Gorthleck, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- We agree the colour with you first
- 20+ years of sealant experience
- Tidy, careful work

Signs you need external mastic in Gorthleck
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
People normally contact us when they notice one of these:
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
In and around Gorthleck, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
