GreenWorks Inspections & Engineering
GreenWorks Inspections & Engineering
At GreenWorks, we know that buying, building, or investing in property is one of the biggest decisions of your life. You deserve absolute peace of mind and confidence in your investment. That’s why we’ve built the nation’s largest privately owned, non-franchise inspection and engineering company—serving with unmatched quality, speed, and care. Unlike most inspectors who only point out problems, GreenWorks provides clear answers, proactive solutions, and cost transparency. Every inspection includes a detailed walkthrough, a comprehensive report with photos, and a free repair estimator so you know exactly what deficiencies mean and how much they will cost to fix. From foundation mapping, plumbing, and HVAC checks to mold, asbestos, radon, and lead testing, our comprehensive services ensure no detail is missed. For homeowners, we are your go-to partner from the first pre-pour on new construction to warranty inspections years later. For realtors, we keep deals moving forward with fast, accurate reports and communication your clients can trust. For commercial investors, we can inspect up to 900 units a day, delivering thorough PCAs, ESAs, and structural plans that keep feasibility studies on schedule. And for builders, we provide engineering-led quality assurance to make sure projects are built right the first time. Founded nearly two decades ago by CEO Harmony Brownwood, GreenWorks was created to raise the bar in an industry that too often settles for the bare minimum. Every inspector completes a rigorous training program—including structural engineering—before serving clients. Our team is backed by licensed engineers, cutting-edge technology, and a full support staff available 365 days a year. When you choose GreenWorks, you’re choosing more than an inspection. You’re choosing a long-term partner committed to safeguarding your property, protecting your investment, and giving you clarity at every step.
