"I had a very nice experience with the Best Air Quality and Restoration team. The price seemed fair to me. I purchased the duct cleaning, mold treatment services. Amanda was very helpful in scheduling my appointment; I was hoping for an earlier date; Dennis offered to reach out to me if the option presented itself, which it did a few days later. On the date of the appointment, Sergei called to tell me he was on his way. Sergei and his crew of one were professional and attentive to my questions and needs, being mindful of my 6 month old. I was very satisfied with the service, attention and professionalism of Best Air Quality and Restoration. I would recommend and use their services again in the future."

"From the first touch to signing the check, removal of a 500 gallon leaking tank from a crawl-space, soil remediation, installing a new tank was fast efficient and smooth. I wish they also did taxes and provided doctor services!"

"No one expects or wants to deal with asbestos removal but after removing old carpet in an old home we unexpectedly found tiles that tested positive for asbestos. Compliance Construction went above and beyond to handle this remediation even when it took much longer than they originally anticipated. James Lang in particular was incredibly responsive to our needs. I hope that I never need asbestos remediation again but if I do I will know who to call."

"I love my basement now! They removed all of the asbestos flooring, adhesive etc. and installed my new floor in 2 days. The employees were very respectful and worked efficiently. They had said 3 days but they hustled and did it in 2."

"Danny was great!!! We are doing a house refi and the appraiser noted a mold like substance in the basement bathroom. I contacted Danny and e answered his phone whenever I called, and was quick to come out to test our mold. In the beginning, he explained that he only tests, does not do remediation and why it isn't good to have a company that does both together. He made this process easy to digest and feel like I wasn't going to go down a road that was an expensive scam. He thoroughly explained the test process, and even told me that it might be just an allergen, which in fact it turned out to be. He sent me a thorough report, and then let me know that the mortgage company could call him directly if they needed any clarification or didn't understand the report."

"When this company came to inspect my home- where I thought there was a problem, I was immediately informed that I did not have a mold problem. He literally wiped what I thought was mold away with his hand, and told me use some Lysol to take care my bathroom cabinet. I am thankful for his honesty and the fact that I didn't have to spend any money for his services. If I ever develop mold in my home, my first choice would be mid-atlantic mold and restoration! The Gentleman that came out to inspect was very kind and knowledgeable!"

Biohazard Remediation questions, answered by experts

It is generally safe to stay in a house that smells like sewage for a short time, but you should get the problem fixed as soon as possible. While the level of sewer gas is usually low enough to only cause minor symptoms, prolonged inhalation can lead to headaches, nausea, or respiratory irritation. High levels of gas exposure can be more dangerous, and high concentrations of methane—a component of sewer gas—can pose an explosion risk in enclosed spaces. If you smell sewer gas in your home, ventilate the area and call a professional to locate, assess, and fix the problem, as it will not go away on its own.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

While bleach can be effective in killing mold, it may not fully remove mold stains from siding. Additionally, bleach can be harsh and may damage certain types of siding. It's recommended to use specialized mold cleaners or natural alternatives that are safe for your specific siding material as a part of your regular siding maintenance. 

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.
