Repointing & Repairs Treatment in Abergavenny

Defective mortar joints are one of the most common causes of penetrating damp in South Wales properties. As mortar weathers and erodes, it opens hairline cracks and voids that channel rainwater directly into the wall thickness — particularly on exposed elevations. Incorrect repointing with modern OPC cement can make things worse by trapping moisture in older lime-mortared walls. EverDry Damp assesses the existing mortar specification and matches repointing materials precisely to ensure breathability and durability.

Abergavenny is a market town at the gateway to the Brecon Beacons, with a mix of Victorian terraced housing, period townhouses, and rural properties in the surrounding area.

Frequently Asked Questions — Repointing & Repairs in Abergavenny

Why does mortar specification matter?

Pre-1919 buildings were built with soft lime mortar. Repointing with modern OPC cement — which is harder and less breathable — traps moisture in the masonry and can cause spalling (face of bricks blowing off). We always analyse existing mortar and match the specification.

Should the whole house be repointed at once?

Not necessarily. We prioritise the most exposed elevations and areas where moisture ingress is occurring. Selective repointing of the worst sections is often more cost-effective and delivers immediate results.

Can you repoint in winter?

We avoid repointing when temperatures are at or below 5°C, as frost can damage fresh mortar before it cures. In South Wales, this limits us mainly to the coldest winter months.
