"Thank you so much for a professional and efficient job! We had a flood in our basement and needed to have our carpet cleaned. Eco Pro cleaned the back of the carpet before it was put back in place. After the carpet was re-installed, they came back to do a complete cleaning of the entire basement carpeting. We put this carpeting in pretty recently, and Eco Pro saved us from needing to replace it. The carpet looks amazing and we are so happy to finally have our basement back!"

"Outstanding service! I could not understand why my downstairs closet was extremely cold upon entry. During my first conversation with Phillip, he conveyed concern and dedication regarding identification and remediation of the unusually cold air. During initial visit, Phillip noted portions of closet were approximately 15 degrees colder than adjoining rooms. After conducting internal and external inspections of the nearby areas, he identified potential source of cold air. A couple days later with outside temperatures in the 20s, Phillip exhaustively sealed external areas of concern. A few days later, he came again to determine temperature differential within the closet. It was now much more comfortable with temperature only a few degrees below neighboring rooms! Throughout the entire process, Phillip was very friendly and knowledgeable."

"Avoid Guardian Basement – False Promises and Poor Customer Service Two years ago, I hired Guardian Basement to fix a water issue on the front wall of my basement. Joel came out, sold me on their system, and guaranteed I would have a dry basement. We also replaced two sump pumps and had the sump well dug deeper. The main selling point was their lifetime guarantee. Fast forward two years, and I have the exact same problem. Every time there is significant rain, water rushes through the same wall. I reached out to Guardian Basement, and Joel scheduled a time to check it out. His tone was completely different this time—defensive and dismissive. Within five minutes, he claimed, “Your system is clogged.” He made this assessment without any real inspection—just by looking at the cement floor and wall. Now, here’s the catch: If you look closely at their so-called lifetime warranty, clogs are not covered. So despite spending thousands of dollars, I’m back to square one. To make matters worse, Joel was incredibly condescending and unpleasant to deal with. After this experience, I looked into their licensing with the state of Maryland and found multiple complaints against them. I am now in the process of submitting my own complaint as well. I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

"Bait and Switchers. DO NOT RELY ON AN ON AN QUOTE FOR JOB THEY HAVEN"T SEEN! IN PERSON. I gave three electricians very explicit information to bid a job. Offered New Dawn opportunity to come make in person quote but they said they didn't need to. Two of three were very close but I picked New Dawn based on these reviews. I paid a $500 deposit and waited several weeks for the service and paid for someone ($200) to be at my house to meet them this morning. Technicians showed up and said they didn't have what was required to do project and "project was out of scope of quote because it required conduit". They were told up front verbally and in text exchanges conduit was required. In fact the text said "Conduit Obviously!". Spoke to Kelly who was one of the owners who confirmed she researched and saw the text exchange and notes but said the person who gave the quote had made an incorrect assumption and that they would not honor the quote and they would have to give me a new quote. When I challenged that (nicely) she hung up on me. Typical Florida scammers."

FAQs for radon gas testing projects in Pasadena, MD

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
