We used LFC for a rear ground floor extension, this was the 1st time we had undertaken major build work, so we were understandably nervous. LFC made us feel very comfortable, there work was of the highest quality and they worked extremely hard; even tidying up at the end of each day. We were consulted on a regular basis as to how work was proceeding and given options for directions forward. I would thoroughly recommend LFC to anyone in need of build work – large or small, their prices are incredibly good and the dedication and attention to detail are very impressive. Very much look forward to using LFC in the future.
