How we handle external mastic in New Byth
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Common call-outs are for joints with sealant missing in places and moss and dirt in joints with no sealant left, across brickwork movement joints, render & cladding joints and joints between brick and frames.
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, so they need a sealant that moves with the building.
Your job is guaranteed for a year, as with all our work.

External mastic in New Byth: local notes
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around New Byth, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
New Byth is about 13 miles south-west of Fraserburgh, in Aberdeenshire. We carry out external mastic for homeowners, landlords and businesses in New Byth and nearby. New Byth is one of 161 places in Aberdeenshire we cover. Aberdeen is on our list too, about 30 miles from New Byth.

What we can’t put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on
- Concrete & block
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
- Façade panels
What happens if it’s left?
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

How to look after the new joints
Aftercare is simple:
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Questions from New Byth
Is New Byth in your area for external mastic?
Yes, New Byth 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, and we will give you a clear price.
Is New Byth within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
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 pick the one that suits your wall best.
What do you need from me for a quote?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around New Byth depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

What we are called out for in New Byth
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Look out for these signs:
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
For an older house near a landmark such as New Byth Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
