About our external mastic in Auchencairn
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. Common call-outs are for old sealant gone brittle and cracked and failed sealant between panels on a façade, on copings & trims, brickwork movement joints and render & cladding joints.
External sealant needs dry surfaces, so outdoor work around Auchencairn is planned around the weather. Tell us how to reach each wall, gutter and roofline.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. 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.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Auchencairn: your questions answered
Does the coastal weather in Auchencairn affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Auchencairn?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
When something else is needed
Before you book, it’s worth knowing the limits:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- Façade panels
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Send us any details you have about the façade.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Landlord and commercial work in Auchencairn
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Landlords and letting agents in Auchencairn can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens on the day
Good joint work is mostly 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 for a handful of joints, longer for a whole elevation. Outdoor work around Auchencairn depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in

Outside joints around Auchencairn
Auchencairn is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
In and around Auchencairn, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. If you live in an older home near Auchencairn Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
