We are a family owned and operated business. We are an independent 3rd party mold testing and mold inspection company. Mold remediation protocol written by the IICRC (Institute of Inspection, Cleaning and Restoration Certification) states that remediation companies should not do their own testing and testing companies should not do remediation, it is a conflict of interest. Not all mold projects needs to be professionally remediated. Our goal is to not only let you know if you do have excessive mold but how did you get it and how can you prevent it in the future by providing honest and outstanding service through dedication, hard work, attention to detail, integrity, and always focusing on our clients' best interest at hand. We know that the secret to our success has and will continue to be our satisfied clients. We will go anywhere in Maryland. Some of our clients include Governor Hogan, The Maryland State General Assembly, Property mangement companies, Insurance companies etc.

"They were wonderful to work with and were prompt in coming out."

"I highly recommend Andrew and his team. When Andrew called me, he made a point of looking at my issue THE SAME DAY. The service was very prompt. When Andrew arrived, he surveyed the situation. Unbeknownst to me, I was having a water leakage issue from a pipe. The active leak was the cause of my mold issue. While it was not part of his job, Andrew helped me dry up the water in my bathroom. Andrew provided me a quote and explained step-by-step what he would be doing. Because of his efforts, I hired him on the spot. Maximum Restoration was VERY PROMPT. I admit... due to the immediate responsiveness, I thought Maximum Restoration was a one-person team (Andrew). Wow... was I surprised (in a good way). "TWO" modern "Maximum Restoration" vans pulled up to my home. These were not white vans with "Maximum Restoration" stickers on them. These vans were painted from top to bottom, displaying "Maximum Restoration"... very professional. Four gentlemen showed up to my home. They took their shoes off at the door and they went to work! Andrew explained the entire process and left his team to do their job. They left fans, a dehumidifier, and negative airflow unit to pull any mold out of the air and trap it in a HEPA filter. They planned to come back two days later to gather the equipment and treat the wood so that future mold would not occur. The leak was supposed to be fixed by a plumber that same day, after Maximum Restoration cut out the mold in the ceiling, revealing the source of the leak. The leak wasn't fixed until the next day. I let Andrew know. Because the leak didn't get fixed until a day later, Andrew knew that the area would not be dry in time. WITHOUT ANY ADDITIONAL COSTS, he decided to let his equipment remain an extra days to ENSURE the area was dry before treating it. I've had water damage before. I wish I'd known about Andrew and Maximum Restoration years ago. They provide excellent service!"

Mold Testing and Remediation questions, answered by experts

After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.

Powdery mildew is exactly like it sounds—a widespread mold that looks like baking soda or talcum powder. It’s usually seen on plants and spread in warm climates, which is why many people first discover this issue in their home greenhouse. Over time, plants have become resistant, but if you see it spreading, baking soda and water can eliminate many cases. Otherwise, consider neem oil or fungicide. 

Yes, mold in the basement of your home will affect the conditions upstairs. Mold spores can travel through the air and into the supply vents of your home’s ventilation system. It is extremely important to remove any mold in your basement as soon as possible so it doesn’t affect the health of those living in the house.

You’ve stored your coats away all summer long, but now that the temperatures drop, you notice they smell weird as you pull them from storage. What’s the deal? If your clothes smell weird after you stored them, they may have been in a moist, dark environment for several weeks or months. This environment is ideal for mildew growth, which can make clothes smell musty.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.
