"Target Radon was very responsive and they worked in increments. They replaced the motor first. When that was not enough the replaced the stack. They continued working until the problem was solved."

"We have used Bob's service for our new house in the past year, from pre-drywall inspection to final inspection before closing.  We were very impressed by his capability to identify unusual construction issues that we cannot find and the builder would not admit.  So, to prepare my 1-yr. warranty repair list, my wife and I decided to invite him come back again. Not surprisingly, again he found important issues that we would treat as cosmetic.   <br /> For example, we saw many paint cracks and peeling off over the year, and we know most of them are caused by settling of the new house.  The builder will come by the end of a year to do cosmetic repair on these defects.  But after Bob's review, he found (using his moisture detector) one of them was actually caused by water leakage from a drain pipe of a bathtub behind the drywall.   <br /> Another example.  Our septic field has been suffering from soil settling for the past year, and the builder was asked to fix twice.  But it keeps on coming back after each fix, with even a larger magnitude (deeper settling).  The builder is going to come and fill it up again.  But Bob told us it is not caused by simple soil settling; it is due to soil erosion/intrusion deep into the septic pipe area, caused by a broken or dysfunctional geotextile.  So, I am asking the builder to fix the root cause this time.  Without Bob's advice, the builder would have fixed this in a same way as the last two times, and I will end up having a collapsed septic field again in a few months, after the expiration of 1-yr. builder warranty period. <br /> Initially I was asking Bob to come back and focus the inspection on heat insulation issues invisible to us (he has an IR thermal graph device).  But he was very honest to tell us we could save money by asking energy auditing service through our utility company at a much lower cost, which will also include blow-door infiltration test as well as IR thermal graph scan.  We did, and the energy auditor did an excellent job. He unexpected found gas pipe leakage in our basement (a big safety issue to us).  Our builder fixed the leakage, but their subcontractor did not have a hand held gas sensor the energy auditor had to confirm it was fixed properly.  So we asked Bob to come back and took a second look, using his gas sensor device.  To my surprise, Bob found two more leakages along the long gas pipe. <br /> So, my wife and I concluded that our money was well spent on Bob's service. <br /> <br /> <br />"

"Mike and team were very knowledgeable and patiently answered all of my questions (and I always have a lot of them when dealing with contractors). They know their stuff and didn’t oversell or make false promises. I already had a mitigation system in place over my sump pit that came with the house, but it wasn’t adequate to service the multiple slabs that make up my foundation. Mike suggested a stepped approach to deal with the “hot spots” in the house and then re-assess whether additional action was necessary. They installed a clear lid over my sump and fixed the trap in my pit so that the existing fan was actually pulling suction on the foundation (and not the open drain from my exterior stairs). They also installed a second system that serviced two slabs and vented out through the back of the roof. Finally, they sealed up some cracks and holes around the foundations. Mike found a solution that was sensible from an aesthetics perspective as well as functional. The pipe runs through my entryway closet, and is as hidden and cleanly installed as I could have hoped for. We had a difference in opinion on how the finished roof flashing should have been done (more from an aesthetics perspective), but it’s on the back of the house behind the chimney so I wasn’t overly concerned about it. The system has reduced my levels to around 1pc/l down from a previous average of about 8 pc/l. So definitely within acceptable levels. I’m only a month in, so will continue to monitor over the next year to determine if any seasonal impacts require further action. I would definitely recommend them and plan to use them again if I need to (although I hope I don’t have to). If you are looking at this and don’t have your own continuous radon monitor, I recommend picking one up."

"Mr. Goldberg performed a radon test for me and did find that I had some moderate radon levels in my home. He's very efficient with what he does. He referred me to a guy named John Sweat to help me deal with the problem. I spoke with the guy and gave me a proposal but I have not heard from him in about a week and a half."

"I sent a text to Mitch late on Thanksgiving eve. Mitch responded early in the following morning and was available for the inspection the following day at my requested time despite this being the Thanksgiving weekend. Mitch arrived with his assistant on time and spent three full hours for all the inspections requested. He was professional and polite. He pulled me a few times during the inspection, showed what he found and explained in detail what could be the potential issues in the future. He covered everything that I wanted to focus on including Roof, Deck, Windows, HVAC, Mold, Termite, Radon and the overall house. I also received the general report and Radon report quickly and on time. I would recommend Mitch to any one who wants to have a thorough inspection of the house. He has good knowledge and experience and gives you an honest opinion of the house. His report also includes the details along with all the pictures and recommendations which will help you make a final decision."

"They were very prompt, professional and did an extremely thurough job with the inspection. The price was reasonable and well worth it for the services provided. It was helpful to have a list of things to repair to send to the seller, and also for us to take care of in the next few months. We also added on a radon test for an additional charge."

FAQs for radon gas abatement projects in Ellicott City, 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.
