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.

"They are the worst company to hire! They unclogged my sewer lines; then dug a hole in my yard left the clean out pipe sticking out on the ground where my grandchildren can trip and fall over it and I can run over it with my lawn mower; now how stupid is that? They left a mess and never came back to clean it up. They took forever to do this job; it seems every day there was an excuse not to work on it. I will never refer this company to no one, and I do not know why they are still in business."

FAQs for radon gas testing projects in La Vernia, TX

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
