Cairnie External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Cairnie. Fully insured, ARBOMaster approved and guaranteed for a year.
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building. For a place like Cairnie, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, the joints are inspected and the access agreed.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

External mastic in Cairnie
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. If you are dealing with cracked joints where brick meets render or frames and weeds or debris growing in open joints, we can help, whatever the surface.
External sealant needs dry surfaces, so outdoor work around Cairnie is planned around the weather. Let us know about access to every wall and roofline.
A 12-month guarantee comes as standard.

Questions from Cairnie
Will you come out to Cairnie?
Yes, Cairnie is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do external mastic in Cairnie?
Yes. Our work covers the whole of Scotland, and Cairnie is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
How to look after the new joints
Looking after new joints is easy:
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
When to call us in Cairnie
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
If you let a flat or house near Huntly station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Walls and rooflines in Cairnie
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
If you live in an older home near Cairnie Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
