“Your dedication and experience helped make this move the easiest we have ever been through. It was tough to build a new house on an infill lot in an older neighborhood. Although the construction site was tight, I never received a complaint from any of my new neighbors. We also appreciated your honest opinion on the building schedule. You delivered good news and notso good news promptly and delivered the house on schedule. Your experience was comforting when we encountered problems with forming and pouring the footer. The soil was bad and we encountered clay. You promptly brought in a soils engineer and we had the footer poured in 48 hours.”

“We chose Jim Kerwin of Decatur Building Services to build our first custom home.  Jim’s experience and professionalism became apparent from the beginning and remained throughout the process.  Several issues arose, but Jim and his expert team managed the situations and kept the project moving forward.  What really impressed us is Jim’s attention to detail and accommodating attitude.  We now live in a house that far exceeds our expectations.  We highly recommend Decatur Building Services.”

“I chose Jim as my Construction Manager for several reasons. First, he has been building homes for over 20 years. That means a lot to me. I wanted someone to advise me that “has seen it all.” My family built a 4000+ square foot custom home on a fully wooded lot. We had an idea of the basic floor plan, but Jim helped with ideas for practical and efficient uses of space. Second, Jim is the owner of his company. Therefore, when I called, he answered. If it weren’t for Jim’s quick response during excavation and attention to detail during the grading and house sighting, my yard could have easily held water because the lot was so flat. Finally, Jim seemed realistic on his construction time line.

As everyone does, I needed to coordinate my family’s living situation during the construction of the home. The financial stress of building is enough, I was thankful that a realistic timeline was set and met. Jim oversaw the design and construction of my home and it looks and feels the way my wife and I intended.”
