Priya K.Rear extension, HollinsfieldRated 5 out of 5 “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.”
Tom and Alice W.Loft conversion, WexbridgeRated 5 out of 5 “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.”
