About Our Basement Finish Service
Most Chicagoland homes sit on top of 800 to 1,500 square feet of unfinished basement space — essentially a blank canvas that can be transformed into a home theater, a gym, a guest suite with a full bathroom, a kids' playroom, or a dedicated home office. Dollar for dollar, finishing a basement is one of the most cost-effective ways to add livable square footage because the foundation, roof, and exterior walls already exist.
Buffalo Grove is known for top-rated schools — and homeowners here hold their contractors to the same high standard.
