How we handle external mastic in Ashkirk
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We work on render & cladding joints, façade panels and brickwork movement joints, and people most often call us about plants rooting in failed movement joints and rigid filler in a joint that should flex.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Every job is covered by a 12-month guarantee.

What else we do in Ashkirk
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why it’s worth doing now in Ashkirk
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. 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.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Outside joints around Ashkirk
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 sound outside sealant is part of that.
In the older streets around Ashkirk Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. In and around Ashkirk, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
What affects the cost of external mastic
The quote reflects the job in front of us. We look at:
- Whether the work is at height

- Which sealant suits the joint
- Any working-time requirements on site
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building for a typical job. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
