Chimney Rendering in Caldicot
Rendering, repointing and weatherproofing chimney stacks — the most exposed masonry on any house.
We carry out chimney rendering across Caldicot and the surrounding Gwent area throughout the year.
Gwent is characterised by valley terraces, stone cottages and postwar estate housing, with damp in solid-wall valley terraces and failed cement render the recurring theme on the properties we survey.
The area sees high rainfall with sheltered valley conditions, which is the single biggest factor in how long any render lasts here. The valleys hold moisture and see limited sun on north-facing slopes, so algae and persistent damp are more common here than the rainfall alone would suggest.
When chimney rendering is the right call. Choose chimney rendering where a stack is spalling, the pointing has failed, or damp is showing in upstairs rooms near a chimney breast.

FAQs
Chimney Rendering in Caldicot
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
Why is my chimney causing damp?
Water enters through failed flaunching, cracked render, open pointing or defective flashings, then runs down inside the flue and shows as staining on a chimney breast, often on the floor below.
What is flaunching?
The mortar fillet that beds the chimney pots into the top of the stack and sheds water off it. It cracks and fails with age and is a very common leak point.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
