External & façade joints in Newtown, Highland
Movement joints in Newtown need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
- Failed seals between different materials
Signs you need external mastic in Newtown
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
People normally contact us after spotting one of these:
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
Around Newtown, as everywhere, external mastic is only as good as the preparation behind it.
Questions to ask before you book
- Is VAT in the price?
- Who turns up on the day
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
External mastic for homes and businesses in Newtown
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Typical jobs include gaps where render, brick and frames meet and plants rooting in failed movement joints, on brickwork movement joints, render & cladding joints and joints between brick and frames.
External sealant needs dry surfaces, so outdoor work around Newtown is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When it is not the sealant
A few problems are outside what sealant work can do:
- Damp that is not coming from the joint
- Movement that’s more than a sealant joint can take
- Cracking across the wall rather than at a joint

How the job changes by surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.

Advice
Also in Newtown
Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like Newtown, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit is normally more efficient than separate visits. We will send you a clear quote for the lot.

Walls and rooflines in Newtown
Harled (roughcast) walls are common in Scotland, 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 failed outside joints work against that.
Whether the job is in Newtown itself or nearby, the right material for each joint matters as much as a neat finish.
