David was on time and very professional. He spent an appropriate amount of time evaluating the 2 areas we had requested. He documented the inspection w/ photos, measurements, and sketches. He provided a verbal preliminary report and is to provide a written final report w/ specifications for the mods we are proposing. (Removing a wall upstairs and a post downstairs.) We were happy to hear that our mods were going to be less complicated than originally thought and consequently less expensive. We have the peace of mind that the proposed changes are structurally sound and will be done correctly.
