    "I was kept informed throughout by Den and his workforce as to what was being done and had been done. At the end of each day they ensured that all their tools were put away and the place was tidy. I would definitely recommend LD & C to anyone wanting works done"

    "We recently had a single storey rear kitchen extension built by LD&C and we couldn't be happier with the result. The team were professional, friendly and clearly knew their trade inside out. The site was kept neat and tidy throughout and the project came in on budget with no nasty surprises. The quality of the finished work is excellent and our new kitchen extension has completely transformed the space. We would have no hesitation recommending LD&C to anyone in the Sidcup area."

    "We found Leadway on Trustatrader having looked at the reviews and having met Den we appointed Leadway as our builder. Outstanding work and fantastic communication. Every aspect of using Leadway was excellent. The team on-site were polite, tidy and very helpful. Could not recommend Leadway more."
