DLJ completed our single storey rear extension and new kitchen this year. From our first enquiry Dave was responsive and informative and helped with queries from building control even before we had given him the work. Work started when promised and was finished on budget, on time and to an extremely high standard. The house has been transformed. Dave’s team and all contractors were a pleasure to deal with, highly skilled, hard workers and friendly and pleasant to deal with. Wouldn’t hesitate to use again if needed and highly recommend to anyone looking for a local builder.

Having had our main kitchen done 3 years ago, we decided to extend it into the dining area. DLJ were very helpful in obtaining matching kitchen units and also managed to find a supplier who could match the work top for us. We are very happy with the finished kitchen and would definitely recommend DLJ.

DLJ were my first choice when I was looking for builders to extend my kitchen. They had previously been recommended by a friend who had used DLJ for a garage conversion and other, smaller projects so I knew I could trust them. I was given a quote and timescale for the work, and everything was completed in time and on budget. During the work I was impressed by everyone’s efforts to minimise the inevitable mess and disruption, covering surfaces inside and out and always sweeping and tidying up before they left. We were very happy and extremely impressed with the work that was done, and we love our extended kitchen. I would not hesitate to recommend DLJ for the quality, value for money and professionalism of their work.
