BZ SCORE: 105
(4 reviews)
Recent review: A year after the job was completed we are still delighted with the work Hammer did for us. Working with Greg and Andres on the design was an enjoyable process. The workers were dedicated and tidy. It was a much different (better) experience than I heard from friends who had other firms do their kitchens.
