Reasonable rates and after hour work. Licensed with 20 years experience and union trained. We do everything from remodels to emergency calls.

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."

"Travis set up the equipment when he was at the house, during the home inspection a couple of days ago (see separate review for the home inspection). As the test needed to be done over a 48-hour time frame, he updated the report originally provided with the results of the radon test. We didn't have to prompt him at all. "Magically" an email with a link to the new report was received on the date we'd been told. Such a pleasure dealing with professionals who deliver what was mutually agreed upon."

FAQs for radon gas abatement projects in Letha, ID

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
