Repointing & Repairs in Caldicot
Expert repointing & repairs treatment for properties in Caldicot, Monmouthshire. Correct mortar specification matched. Free surveys with no obligation.
Caldicot's post-war housing stock frequently develops condensation problems, while older rural properties in the surrounding area are prone to penetrating damp through solid stone walls. Rising damp is common across both housing types.
Repointing & Repairs Treatment in Caldicot
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.

Frequently Asked Questions — Repointing & Repairs in Caldicot
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.
