Quinn Sizemore

Meet Quinn Sizemore

Quinn Sizemore is a multi-disciplined construction and real estate professional with over 10 years of hands-on experience in the Southern Suburbs of Chicago. As the owner and authorized independent builder of the Frankfort Custom Home Design Studio — an official Wausau Homes dealership — Quinn delivers precisely engineered, fully customized homes across Will and Lake Counties, IL and Porter County, IN. His studio features state-of-the-art 3D home rendering so clients can visualize every detail before a single nail is driven, with move-in timelines as fast as three months.

Beyond custom home building, Quinn owns Third Coast Exteriors and The Roofing Company — certified exterior contracting firms serving the greater Chicago market. From residential re-roofing and metal roof coatings to large-scale commercial flat roofing systems, his crews deliver manufacturer-backed installations. Quinn holds a PolyGlass Certified Contractor credential, a Xactimate Certification, and a MetLife IA Certification — making him a credentialed insurance adjuster who understands claims from both sides of the table.

As a licensed Illinois real estate broker with Third Coast Real Estate Advisors (brokered through eXp Realty), Quinn brings a rare edge: he is simultaneously the builder, the broker, and the contractor. Whether you are buying land, designing a custom home from scratch, navigating a storm damage claim, or selling a new construction property — Quinn Sizemore is the one professional who can walk you through every phase.

Our Mission

Most clients never meet the person who builds their home, writes their roofing claim, and holds their real estate license. Quinn Sizemore is the exception. Every project — from custom home design through final walkthrough — is driven by the same standard: deliver more than promised, communicate without fail, and build something that lasts decades.
