"I'm completely satisfied with the work that John's team did. They were extremely professional and knowledgeable. The workmanship is superb. Best of all, the system works as promised and reduced the radon concentration based on subsequent tests. I could not recommend them more highly."

"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."

"I have zero complaints about our tech, Jack. He was thorough and communicative! We have a system installed through the roof and he was able to paint the exhaust pipe to match the shingles. The front office wasn't as great. We had to schedule a follow up visit because the initial install wasn't going to work. Unfortunately they never put me on the schedule the second time. So my install day came and went but we didn't hear anything from Swat. I calle the next day and no one knew what I was talking about. Our account manager (Brian) was very apologetic and offered to take some money off our install because of the confusion and the fact that there were no available appointments until August 11th. Luckily they were able to add me to the top of their cancellation list, so we ended up with a system just 3 days later. I appreciate their willingness to make it right with me. I would reccommend them to others looking to have a radon abatement system installed."

"The job went well overall. Magnolia's estimator and residential field supervisor, Sam Musser, is also a licensed AC system installer, and with his wealth of knowledge and experience he was able to answer all of my questions concerning the installation. Sam was also very responsive in addressing the few concerns I raised during the installation process, and his installation team was very polite, professional and diligent. This included not only Magnolia's employees, who installed new high efficiency TRANE air handler and condenser units, but also the two licensed subcontractors for the new ductwork and the electrical hook up work."

"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."

"I've used Floodbusters twice in the last two years. The first time they came out and sealed a crack in my utility room to exposed concrete. The job was solid, but the sealant they used looked a bit sloppy. I called and the same week they came out and painted over it. Now it looks good! This was in 2019. This past February 2020 I had them come out again, this time they had to remove drywall to access where the crack was. Two different men came out then the first time. They did a pretty good job. All I need now is for my drywall to be replaced and another successful job will have been done and in the books. I really appreciate this company and highly recommend!"

"Travon explained the process in detail. This includes the EPA regulations, containment of the work area, what we would have access to during the work, treatment of the HVAC system, air scrubber use, construction of a decontamination chamber and airlock, sealing the exposed floor after the mastic removal, and waste material bagging, sealing, and disposing. Education was important. Travon made flooring recommendations to avert future mold problems. There were plenty of places they could have cut and sealed tiles but chose to do the detailed work to remove the tile, mastic and seal the area. The job was done efficiently and the surrounding area was cleaner than before the work started. Protect the Investment’s quote was higher than the competitors but it was well worth it, knowing that they took the extra effort to assure there were no scraps of asbestos that would be exposed in the future and for a job exceptionally well done. I am extremely pleased with the services performed."

FAQs for radon gas abatement projects in Gwynn Oak, 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.
