"Mike came out to do Radon Mitigation at our property. We had received quotes from some local companies reaching into 5 figures! Mike not only did the job for a 3rd of the cost, but the radon levels were massively reduced to proper safe amounts. High quality materials used in the work, and he completed everything in one day. He is a super nice guy, who is very experienced at what he does, straight forward, and honest. You can't go wrong, and I would definitely recommend him to friends."

"The service went better than we could have expected. We were contacted right away and were given a quote. Work started when we wanted it to and was finished in a timely manner. The workers on site were very considerate, asked questions, and were more than respectful of our home and our wishes. I would highly recommend Really Fast Rapid Radon Remediation to anyone needing work done to their home."

"we got our bid from them and they also gave us an estimate. I don't remember the estimate it is out of my head. But their estimate was reasonable. We actually got three  quotes to decide, but after getting the quotes we thought it was not in our budget to do. The three people that  came to give us their bids, they seemed least interested in the project. My wife and myself have been working on the budget and I'm going to call them again for sure."

"I was very satisfied with the work performed by HomeCheck (Steve  Blaha).  First, all inspection rates were listed right there on their  website (listed in matrix form by size of house and age of house).  I like seeing fixed rates like that.  Sure enough, the amount shown on the website is was what I ended up paying.
Steve responded to my inquiry on the same day and I was able to book an appointment with him a few days later.  He showed up on time and did a very good job inspecting the house.  He spent more than three hours going everywhere  and did a thorough job.  Very knowledgeable with lots of experience and it shows. The report was well done and very useful.
I can easily recommend HomeCheck for home inspection service.

FAQs for radon gas abatement projects in Portland, OR

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.
