Reasonable rates and after hour work. Licensed with 20 years experience and union trained. We do everything from remodels to emergency calls. Possible work, but not limited to: Clogs, drain cleaning Re-pipes Fixture installs Water heaters and softeners Disposals and dishwashers Pools Sewer and septic Sump and well pumps Water treatment, filtration and UV units Tankless water heaters Radiant heat In addition, Fitzgerald Mechanical is capable of completing all construction from foundation to key in the door. We belong to a co-op of skilled trades that will provide the convenience of only having to work with one contractor from start to finish.

"I gave Ryan and Heather a $6,500 deposit for their bid to replace my main sewer line on Oct 15, 2019. They dug two 4 foot holes in my backyard and then disappeared for 5 months. I called, emailed, and texted every few days letting them know the sewage leaking in my basement was getting worse by the day. Over the 5 month period they would either completely ignore my communication or give me excuses ranging from being gone on hunting trips to moving on to other jobs and promising that I was still a priority to them and that I was next on their list. It finally came down to me getting another contractor to come do the job, and they were able to complete it in 2 days. I asked Ryan and Heather for my deposit back and after a week of excuses why they wouldn't be able to get me my check I told them I felt I had no choice but to sue them because I needed the money to pay the other company that actually did the work. They eventually gave me a partial refund with no explanation of why they kept $2,500 of my money. I've messaged them to see if they can explain how they can justify it, and they haven't gotten back to me. I would strongly recommend not using their services, especially if it involves a deposit up front. Ryan and his crew were very nice, and I enjoyed the time I got to spend with them, but I've never been so frustrated working with a contractor. I feel cheated and in my opinion they simply stole $2,500 from me."

FAQs for radon gas testing projects in Letha, ID

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.
