"Buyer Beware!!! Once the installation is complete, you're on your own. I own a digital radon detection device. It's been over a month since the installation and the radon levels are above recommended levels (4/20/23 4.4, 4/21/23 5.2, 4/22/23 4.2, 4/28/23 6.4). I didn't monitor it every day but today it's at 4.3. When I contacted John the owner on 4/19/23, he suggested two options. 1. Install a larger fan for $150 which he said may or may not work and 2. Call some company to come out to run a scope to see if there is a blockage. He couldn't suggest a company because he didn't know any. The one option he didn't offer which I suggested, was to have one of his technicians come out to take a look at it. Needless to say I am not a happy customer. I paid $1,300 for something that doesn't work with no recourse. I will be contacting the BBB though."

FAQs for radon gas abatement projects in Denver, CO

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.
