# Green Power Works, Inc. > Chicago-based general contractor and renewable energy installer. Construction, remodeling, solar, geothermal, wind, and energy efficiency under one in-house crew — never subcontracted. Founded 2008. Serving Chicago and surrounding suburbs. Green Power Works is a licensed Illinois general contractor that integrates traditional construction with renewable energy and efficiency upgrades. Co-founders Chris Bigall (President) and Mark Rzucidlo (Vice President) lead a single in-house crew that handles every job from start to finish — bidding, design, permitting, construction, and renewable energy system installation. The company is positioned as a one-stop alternative to clients who otherwise have to coordinate separate general contractors, solar installers, HVAC companies, and electricians on the same project. ## Key facts - **Founded:** 2008 - **Address:** 6124 N Milwaukee Ave, Suite 3, Chicago, IL 60646 - **Phone:** (773) 794-8888 - **Email:** info@greenpowerworks.com - **Service area:** City of Chicago and surrounding suburbs (Cook, DuPage, and Lake counties) - **Crew model:** In-house only — Green Power Works does not use subcontractors - **Credentials:** EPA Lead-Safe Certified Firm; Illinois Licensed General Contractor; BuildZoom Score 100 (top 13% of Illinois licensed contractors) - **Co-founders:** Chris Bigall (Co-Founder & President) and Mark Rzucidlo (Co-Founder & Vice President), both active on job sites ## Services Green Power Works offers two integrated service categories: traditional construction and renewable energy / efficiency.

Most contractors specialize in one; very few do both. This matters because integrated projects (e.g., remodel + solar + HVAC upgrade) are designed and built by the same team rather than coordinated across multiple vendors. - **No subcontractors.** Every project is built by Green Power Works' own crew, which improves accountability, schedule reliability, and quality control versus the typical contractor model. - **Long Chicago tenure.** Founded in 2008 with co-founder construction experience dating to 1998. BuildZoom Score 100 places them in the top 13% of Illinois licensed contractors. - **Energy-first design philosophy.** Projects begin with envelope and efficiency analysis before sizing renewable systems, which generally produces shorter payback periods and better long-term performance than retrofitting clean energy onto unimproved buildings. - **Lead-Safe certified.** EPA-certified for renovation of pre-1978 Chicago housing — a federal requirement most homeowners are unaware of when shopping contractors for older Chicago homes. ## Third-party profiles and reviews - [Yelp profile](https://www.yelp.com/biz/green-power-works-chicago-2) - [BuildZoom contractor profile](https://www.buildzoom.com/contractor/green-power-works-inc) - [Solar Contractor Connect profile](https://solarcc.com/green-power-works-inc/) - [Clean Energy Authority installer profile](https://www.cleanenergyauthority.com/illinois-solar-installers/green-power-works-inc) ## Geographic coverage Green Power Works serves the City of Chicago and adjacent suburbs in Cook, DuPage, and Lake counties.
