About C&M Developments

The development side of C&M Jones Groundworks Limited, a Mountain Ash contractor with more than 50 years of combined experience below ground.

Why a groundworks contractor builds homes.

C&M Jones Groundworks has spent its working life on the hardest part of building in the Valleys: the ground. Drainage and sewer infrastructure, foundations, reinforced concrete and retaining structures, for housing associations, contractors and private clients across South Wales.

C&M Developments exists so that the same experience can carry a site all the way. Instead of getting a scheme out of the ground and handing it on, we take it from the first site walk to finished homes, with one team and one point of contact.

C&M Developments is a trading name of C&M Jones Groundworks Limited. Same company, same people, same accreditations.

How we work

  • We price the ground because we dig it

    The ground is where Valleys schemes run over. Our estimates for it come from the team that does the work, not from a desk.

  • One team, one point of contact

    From the first conversation to the keys, you deal with the same people. Nothing is lost between contractors.

  • Accredited and fully insured

    CHAS accredited and fully insured, with CSCS, CPCS and Street Works certification, and approved to install Platipus earth anchoring systems.
