MoldGone is a full service mold inspection, air quality testing, remediation, and reconstruction company with over a decade of experience. Our inspectors and technicians carry the highest and most recognized certifications in the industry. Whether your are a residential or commercial customer seeking mold testing or remediation services you can be assured that the project will be professionally managed and properly certified. There are many companies that offer mold remediation - make sure that the company you choose has an industry recognized mold remediation or inspection certification such as the American Council of Accredited Certification (ACAC) or equivalent. MoldGone is unsurpassed in its commitment to customer service excellence, provision of only the highest caliber service, and providing unsurpassed value in every project or inspection delivered. MoldGone's customers have ranged from the residential homeowner to private schools and churches. In fact, when the Sisters at a private Catholic girls school in the Washington, D.C. area needed a company to treat mold in the Sister's private archive room, complete with 100 year-old manuscripts, they entrusted MoldGone, LLC to do the project. On another project that involved removing mold from a 30 foot ceiling above a filled indoor pool, when the scaffolding company wanted several thousand dollars to build the necessary scaffold to reach the treatment area MoldGone built its own providing the customer significant savings. At MoldGone, LLC. we constantly strive to find the most cost effective way to fully address each and every mold condition. MoldGone technicians are trained specifically for mold treatment and remediation. They are also required to have construction experience since many of our projects involve demolition and reconstruction. Technicians are held to the utmost highest levels of quality with each project receiving a thorough walkthrough by management before it is deemed complete.

"MoldGone was somewhat hard to deal with but ultimately agreed to work on this until the air was normal and they had good reviews so I hired them. They did the first treatment and I had an air test done. It showed there was still high mold levels. I immediately asked them to return to fix it--as we had agreed. Jay argued and argued but eventually agreed to. On the day agreed, they claim they came but could not work since no one answered the door. We had already agreed I would not be there--and that both doors would be open so they could begin. Jay forgot to tell the workers AND he failed to call/e-mail me while they were there to ask me. So I am out ANOTHER $300 for the hotel and still no mold remediation. I again sent e-mails asking when they would come back. Jay admitted the communication failure was his fault but still said he would not reschedule the job. This time Jay refused to do the job--instead offering to just do "cold fogging" Next, Mike Mulieri(VP of the company) entered the picture. He assured me he would resolve the problem. Instead he made it worse. He dragged it out, argued back and forth with Angi and still refused to refund money or do a re-treatment of my place. I view MoldGone as slick, dishonest folks who try to talk their way out of any problem- but not actually remedy their mistakes. Now I'm on my way to the courthouse."

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."

PROTECTING BY INSPECTING! Lead poisoning is no laughing matter. Worldwide, about 143,000 deaths per year result from lead poisoning, and lead paint is the most common perpetrator. You can prevent lead poisoning from taking a toll on you, your family, and your home by having your property inspected. Reliable Lead Inspection Services, LLC has helped countless homeowners across Baltimore, MD and the surrounding counties with their home lead inspections since 2014. The state of Maryland requires that all properties – including apartments, condos, townhouses, lofts, and single-family homes – built before 1978 have a new lead inspection certificate every time the property is rented or sold. Even if you’re not in the market to buy or sell property, it is always a sensible decision to have any home inspected before doing renovations. You never know what could be hiding in those walls! I can provide 24 hour results if needed. Available 7 days a week. MDE Lic #15208 Ask us about our Senior, Police, & military discounts!

"Norman, was very friendly, knowledgeable and informative. He explained everything he was doing through the process. I would highly recommend requesting Norman."

We are experts in the residential and commercial radon mitigation trade and are committed to quality from the beginning to the end of your project. 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."

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

FAQs for radon gas testing projects in Taneytown, 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.
