About Calder & Rowe

17years on the tools

Building in Wexbridge since 2009

Two builders, a small directly employed team and the same site lead on your job from start to finish. We take on a handful of projects at a time across Wexbridge and the villages around it, and we price from drawings, so the figure you sign is the one you plan around.

  • They found an old drain under the footings and walked us through the options that morning, with prices. It added two weeks, and we knew why at every stage.
    Rated 5 out of 5. Priya K.Rear extension, Hollinsfield
  • We lived in the house the whole time. The new stair went in last so we always had a landing, and the site was swept every evening before they left.
    Rated 5 out of 5. Tom and Alice W.Loft conversion, Wexbridge
  • The steel delivery slipped and we started a week late, but they told us straight away and finished on the date they gave us after that. Building control passed it first time.
