Guardian Basement Waterproofing understands your basement waterproofing needs. We know how to detect the source of water intrusion and stop leaks before they happen. We help our customers reclaim their basements from water, mold and mildew by doing what we do best: finding and repairing the source of their water-related problems. Guardian uses only skilled and experienced technicians to do the job right the first time! As a basement waterproofing company with more than 40 years of waterproofing experience, Guardian stands behind its work with a Lifetime Guarantee. Additional phone number - (410) 484-9812.

"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."

FAQs for radon gas testing projects in Woodsboro, 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.
