- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
How we handle external mastic in Cardrona Village
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We’re often asked to deal with hard, crazed mastic that has stopped moving and joints pointed up with cement by mistake, on concrete & block, façade panels and joints between brick and frames.
External sealant needs dry surfaces, so outdoor work around Cardrona Village is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Point out the joints to other trades
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Wash walls gently around the sealant
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Landlord and commercial work in Cardrona Village
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Outside joints around Cardrona Village
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home 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.
For an older house near a landmark such as William Cree Memorial Church, an extension built onto an older house moves differently, and the joint between them takes the strain. In and around Cardrona Village, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Why act early in Cardrona Village
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What the job involves on each surface
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Your questions about external mastic in Cardrona Village
Do you cover smaller places like Cardrona Village?
Yes, Cardrona Village is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with external mastic in Cardrona Village?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
