"Brian was really friendly and professional, and you could tell he was very thorough. He explained everything in a way that was easy to understand during the inspection, and the report he sent after was super detailed with pictures and notes on all the systems in the home. I especially liked that he included a section that called out the main issues to focus on. Overall, we were very happy with his service and would definitely recommend him to anyone."

"This company was professional from start to finish! Setting up the appointment was quick and easy, they showed up on time and were concerned with my needs. They wanted to make sure the system was going in the proper spot, both inside and outside, and wore a mask and booties the whole time. I was impressed and will hire them again!"

Small jobs welcome

My name is Lexi, and I am the owner/operator of Bats in the Belfry Home Inspection.\n\nMy highest priority is educating and advocating for my clients. I have found that most people know very little about the care and maintenance of their homes, leading to expensive problems later, so I aim to help with that. During the inspection, I want my client involved in the process. After each inspection, I sit down with my clients and go over how to read the reports, give you tons of documents and resources to help you on your journey, and you can call me any time with questions. \n\nA big reason I got into home inspections was to help people like me. People who have survived trauma and abuse who might not feel safe with a strange man alone. Or for single moms, people in the LGBTQ community, and anyone. Safety is a high priority; I always check all locks and windows and have offers through ADT. I want to be that safe person who can assist in ways that others can not.\n

FAQs for radon gas testing projects in Spokane, WA

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.
