"As a designer, it is crucial to have a good contractor to refer to my clients. After all, they are an extension of the experience that we provide for the design and construction process. JEF Construction not only meets our expectations, they exceed it. Their service and quality of work is right on target and I look forward to working on many more projects with this fantastic crew!"

− Tara Baker-Paries // Founder of Red Dore Studio, LLC

"I am a Principal at Arcsine Architecture and have had the pleasure of working with JEF Construction on two projects over the past two years. JEF Construction has always had a positive attitude on all projects and consistently come to the table with solutions and professionalism. James Ferguson, the owner, is present on all projects and always brings a unique sense of collaboration."

− Adam Winig // Principal at Arcsine Architecture

"James is a perfectionist who sets high standards for himself and those he employs. He goes above and beyond to ensure that client is satisfied, and his attention to detail really shows in the quality of his workmanship.

He is conscious of budget and deadlines at all times and communicates well to ensure that his clients are always informed. I thoroughly recommend James and his team to any company or individual seeking a contract who is a cut above."

− Ray Snook // Owner/Operator at Dickey's Barbecue Pit

"James is hard working and honest. Over the years, he has worked on several projects for me (an addition and the construction of a new home) and I have always been impressed with his work. Along the way, he proposed several creative ideas that improved the final design."
