How we handle external mastic in Backburn
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on render & cladding joints, copings & trims and concrete & block, and people most often call us about rain getting behind render or cladding at a joint 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.
Big or small, it’s backed by our 12-month guarantee in Backburn and across Aberdeenshire.

Common problems we fix in Backburn
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for these signs:
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
Letting a property close to Huntly station? Then split movement joints are easy to miss on a rental until damp shows inside.

Outside joints around Backburn
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Historic houses like Leith Hall (about 2.8 miles south) are a reminder that the area around Backburn has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to St Andrew's Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
FAQs for Backburn
Is Backburn in your area for external mastic?
Yes, Backburn is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Backburn?
Yes. Backburn is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so it doesn’t stand out.
How long will you be here?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll say how long yours will take.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
The process
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Backburn may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Advice
What affects the cost of external mastic
Every job gets its own quote. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- How many rooms, windows or areas are involved
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Where the job is, and your postcode
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, email us at info@mrmastic.co.uk.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
