Mainbuilt began in 1957 with company founder, William R. Main. Originally named WR Main Contractors, William "Bill" started building homes and providing construction services as personal projects for friends and family. It wasn’t long before word of mouth spread which led to creating a trusted, well-respected, custom home building firm that continues to serve the Greater Des Moines Area. Bill wasn’t just the owner but a hands on worker. As the company grew, he was able to expand from completing one project at a time, to 3-4 large projects simultaneously, while still maintaining his high level of quality control. 


As the years went by, WR Main Contractors grew to become Mainbuilt, a second generation "boutique" custom home construction company. Mainbuilt has always been a family business.  The current owner, Bill's son, Mark Main, can remember helping his dad with simple tasks such as cleaning up and carrying small tools while he was in elementary school.  Growing up in the company, Mark learned the art of construction by physically working with his father. He later officially joined his father in the business and continues to uphold the company’s reputation for high quality craftsmanship, originality, and dedication to detail.

When you work with Mainbuilt, you’re a part of the team, because our intention is that your custom-built home has your mark, not ours. We want you to enjoy your home-building experience so that you can look back on the project and say, “That was really fun!” after all, it will be your home.
