"I recently had my basement remodeled and we discovered asbestos in the drywall that needed to be removed. I called Clean Sweep and a few other contractors for quotes. Matt at Clean Sweep was very knowledgeable and answered all my questions I had regarding the process. He walked me through step by step and gave me and my wife confidence that the job would be done professionally and safely. Matt's team took care of the job ahead of schedule and we were able to complete our remodel in a timely manner. He was also able to recommend some contractors to help with some of the electrical work I needed done. 10/10 experience. I would highly recommend."

"Edge Environmental had been purchased and is now The Majors Group. Sharon was very knowledgeable and informed me that all testing is done by one company in Denver, and that I could get the testing done for $40 by taking it to the lab myself. Another company that contacted me wanted to Charge $400 for the same test by the same lab. The Majors Group won my trust with that disclosure. The staff who came and removed the asbestos were on time, thorough and cleaned up the work space. The price was significantly less than then next higher bid. I feel that I received a great value for the money."

"All and all they were professional on time and I really needed to know the answers I got. But it would have been nice if they had encluded the radon test, for the price paid! Also I was told they would help me all the way through even with resources and med. if needed. To good to be true. Maybe a little."

"Rob called on my request for remediation immediately, and by the way, no other Radon company called me back from this site! We had failed a radon test with an inspection to sell our home. Square One scheduled to look at the project right away and was timely with the estimate. Soon after, the work was performed efficiently and with the least visible "intrusion" as possible in the basement space. He was very professional and knowledgeable. Would recommend. (I am in AZ but scheduled this for a home in Glenwood)"

"Justin, Zack, and their team members are all great. From my first conversation with Zack, I could tell he was hard working and honest. That same day Justin drove up from Denver after 5:00 pm on a Friday to review the damage and scope of project. Through out the entire project (Asbestos Abatement and mold removal) their team was honest, hardworking, communicative, and priced competitively. We also appreciated the supervisor that was on site (Junior). He was professional, knowledgeable, and was there at 8:00 am to get it done. These guys are the real deal and were truly helpful during a tough time. I would absolutely hire them again and recomend them."

Biohazard Remediation FAQs, answered by experts

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

Deciding whether to use bleach or vinegar to eradicate mold on concrete is dependent on personal preferences, safety concerns, and the severity of the mold issue. Bleach is a powerful disinfectant that kills mold and its spores, but its strong fumes and potential health risks make it a more aggressive approach. It's generally a better option for handling outdoor concrete stains. White vinegar, however, is a safer and environmentally friendly option that can eliminate mold. Although it may take longer to show results, vinegar has a milder odor and is less likely to cause discoloration than bleach.

Symptoms of sewer gas poisoning include nausea, dizziness, extreme drowsiness, and headaches, according to the Wisconsin Department of Health Services. Exposure to higher concentrations for long periods of time could also lead to unconsciousness due to a lack of oxygen, aka suffocation. If you think you’ve been exposed to sewer gas for a dangerous amount of time, seek medical care immediately. Do not return to the site of exposure, after you’ve received medical care, call a pro for help.

Fumigation performed by licensed exterminators is safer and more effective than store-bought foggers. That’s because there are a lot of harmful substances and risky techniques used during such a service, and using or doing them without sufficient knowledge can put both you and your home in harm’s way. When in doubt, let a pro take care of tasks like this.
