How we handle external mastic in Skirling
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are panel joints letting water in and hard, crazed mastic that has stopped moving.
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.
Big or small, you get the same 12-month guarantee in Skirling and across South Lanarkshire.

Skirling buildings and the weather
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Whether the job is in Skirling itself or nearby, the right material for each joint matters as much as a neat finish.
Skirling is about 16 miles south-east of Carluke, in South Lanarkshire. Skirling gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. 139 places in South Lanarkshire are on our list, from the larger towns to small villages. There’s also a page for Edinburgh, roughly 23 miles from Skirling.

What affects the cost of external mastic
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- The type of sealant required
- How easy the joints are to reach
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- The problem you’ve noticed
- Whether it has been sealed before
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, send an email to info@mrmastic.co.uk.
How the job changes by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
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.
Do you need external mastic in Skirling?
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
People normally contact us when they notice something like this:
- Panel joints letting water in
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
Around Skirling, as everywhere, external mastic is only as good as the preparation behind it.

FAQs for Skirling
Do you cover smaller places like Skirling?
Yes, Skirling is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is external mastic in Skirling guaranteed?
All our work, in Skirling and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
The process
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around Skirling 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.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Advice
When it isn’t the sealant
In fairness, some problems need a different trade:
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Façade panels
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
Why act early in Skirling
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
