External & façade joints in Cadder, East Dunbartonshire
We cover Cadder for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Brick movement joints where the sealant has split
- Panel joints letting water in
- Sealant pulling away from one side of the joint
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
External mastic in Cadder
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving, we can help, on copings & trims, façade panels and render & cladding joints alike.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
All of our work is guaranteed for twelve months, in Cadder and everywhere else we cover.

What external mastic looks like in Cadder
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 joints where harling meets other materials need a sealant that can grip and flex.
If you live in an older home near Cadder Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Bishopbriggs station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Do you need external mastic in Cadder?
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Common reasons people contact us include:
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
If you look after a building such as Bishopbriggs Academy, its movement joints, gutters and trims need looking after like any other building’s.

Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. 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.

FAQs for Cadder
I let a flat near Bishopbriggs station. Can you help?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Will you come out to Cadder?
Yes. Cadder 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.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What information do you need?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
How long does external mastic take?
Most jobs take anything from a few hours to several days, depending on the building. Your quote will say how long we expect yours to take.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, large or small.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Aftercare tips
A little care helps the new joints last. Our advice:
- Don’t let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
- Fix overflowing gutters above sealed joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

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. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
