Doomis Custom Builders is a family owned and operated firm founded in 1973. Brothers Tom and Mike Doomis have made a name for themselves and their team as one of the premier custom construction and renovation firms in the Chicago suburbs. 

​With over 40 years of building experience, Doomis Custom Builders is known in the industry for attention to detail and its emphasis on using quality products and materials. They wouldn't use anything in your home that they wouldn't put in their own. When you cross the threshold of one of their projects, you sense the pride in craftsmanship and personal dedication that has built the Doomis reputation for almost half-a-century.

Brothers Tom and Mike Doomis have worked together to grow this family business. Both of them have extensive experience as carpenters and oversee every aspect of the design/build process. They treat their clients' homes as if they are building for their own family. Mike and Tom have not lost sight of what has made them a leader in the custom home and renovation industry. "We believe in quality. It is so true that, especially in the building industry, you get what you pay for. To us, craftsmanship is an art. The home or remodel we complete represents the dreams of the people who live there. It's our job to make sure those dreams become an enjoyable reality. It's our privilege to be a part of that dream."
