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

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.

Mold doesn’t require much airflow to make it out from behind walls and into your living space, making you sick. HVAC systems can actually pull the mold from behind walls and spread it through your home. While the mold may be out of sight, moisture transfer from the wall can also spread the mold from behind the wall into your living space and air. Any cracks in the walls or bad insulation only compound this effect. 

Water damage doesn’t always cause mold and wood rot, but it can. Both mold and wood rot require moisture in the wood to form, so water damage that continues to leave water or moisture behind can lead to both issues. Water damage and mold often go hand-in-hand, but you can prevent mold growth after water damage by addressing the source of moisture and drying out the area quickly. The same goes for wood rot. The longer you let water damage go, the higher the risk of mold and rot.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.
