"We were referring to Target Radon Mitigation by our inspector for our house inspection. I called Steve on Friday to set up an appointment to get the radon levels in a house we were under contract on tested. Steve was super friendly and stated he would drop the test off first thing Saturday morning and we should have the results of the test within 72 hours. That would make our results come in on Monday, Tuesday at the latest. Called on Monday, was told wait another day. Called Tuesday, was told wait another day. Our realtor and inspector called us and told us over the weekend a test was not dropped off. I called Steve and asked what was going on. He promised he dropped a test off and did not know why the results were not yet in. He called the lab on Thursday and they stated the test was never received. He called USPS and they said it was at the post office. If it was overnighted as Steve promised us it was, it should have gotten to the lab Tuesday at the latest. We ended up canceling the order completely. I am not sure if the test was ever really done, but what a headache. Steve was very rude and defensive when confronted about what was going on. After we asked Steve if he ever did the test he said we were calling him a liar and fraud. Steve called our inspector and ripped him a new one. I feel this is extremely unprofessional. Because of all of this, our inspector and realtor both refuse to use this company in the future."

We are family owned and operated providing award winning services since 1998.

"John and his team were life savers for us- literally! We had hired a different radon mitigation company (nationwide) and needless to say, their system did nothing! I have two little kids and was so frustrated with the levels staying high. I was looking for someone who could possibly repair the existing system which is how I came across radon abatement services. They had videos and pictures on their website, of all the wrong work that was done by contractors. I figured these guys know what they’re doing. And know they did! I had emailed John to tell him our situation and he got back to me and explained everything in detail. He told me what and why our house needed a different system. I had not given him a single penny and he was so gracious to share his expertise with me. Ofcourse, Eventually we hired them to install a new radon mitigation system in our house. Within the day of installment, our levels went down below 4 and have stayed below 2 consistently thereafter. I cannot thank John enough. Their prices were also reasonable. I would give them 10 stars if I could."

FAQs for radon gas abatement projects in Annapolis, MD

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.
