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.\n\nUnlike 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.\n\nFor 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.\n\nFounded 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.\n\nWhen 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.

Radon Detection and Reduction questions, answered by experts

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).
