Questions from Yarrowford
Can you do external mastic in Yarrowford?
Yes, Yarrowford is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Yarrowford?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will tell you how long to expect.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
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.
What colours does the sealant come in?
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.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Yarrowford may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

External mastic in Yarrowford: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Yarrowford, as everywhere, external mastic is only as good as the preparation behind it.
Yarrowford is about 7 miles south-west of Galashiels, in the Scottish Borders. Across the TD7 area, we can carry out external mastic at your property. Across the Scottish Borders, we cover 89 places, and Yarrowford is one of them. We also work in Edinburgh, about 28 miles from Yarrowford.

Looking after it afterwards
After the cure time, these simple habits help:
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
What we can’t put right
We’ll always be straight with you, so here’s what sealant cannot fix:
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.

What we are called out for in Yarrowford
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
The most common problems we see are:
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
Bowhill House, about 1.8 miles south-east, is one of the historic houses in the wider area around Yarrowford.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
