Louis was prompt and professional. Reviewed the structure of our entire house from basement to first and second floor and attic. He wanted to understand what we were looking to accomplish. He provided broad estimate for different ways of handling the work letting us determine what we wanted to accomplish.
Once we advised which plan we were interested in, he provided structural drawings for that design.
We did ask him to recommend construction firms to cost out the work. We did not follow up on this because we are not ready to move forward on this project.
In the future, when we redesign a substantial portion of our town house's interior we will call him first to perform his survey to see if what we dream is possible.
