Luis responded very promptly and gave a fairly priced quote for the requested work. He was very kind in doing initial feasibility assessment without any cost that revealed my project may not be possible due to code issues. He was very responsive and collaborative throughout the discussion. Truly impressed by the service and will surely use him for any future architectural or structural work.
