Builders in Risca
Extensions, conversions, renovations, retaining walls and repairs for homes in Risca and the neighbouring valley communities.
Building work for valley homes
We take on building work of every size in Risca, Pontymister, Crosskeys and Cwmcarn, from a rebuilt garden wall to a full extension. Valley houses bring sloping plots, stone walls and awkward access, and we plan each job around them.
Our team is professionally trained, fully licensed and insured, and uses top-quality materials on every project. We offer a free initial consultation, and a competitively priced, no-obligation quote before any work is agreed.

Local knowledge
Building in Risca: what to know
Risca is in Caerphilly county borough, so planning applications go to Caerphilly County Borough Council, not to Newport, although the town is only a few miles up the A467.
Two things set the area apart. Much of the housing stands on sloping ground, which makes retaining walls and drainage a normal part of the work, and the town lies within the coalfield, so we obtain a mining report before designing any new foundations.
