Many homeowners in Frederick rush to hire the first mold contractor they find online, only to discover later that the company isn't properly licensed. It's a costly mistake. Before you call anyone, verify they're licensed by the Maryland Home Improvement Commission (MHIC) at dllr.maryland.gov. Mason-Dixon Restoration is worth considering - they hold a 5-star rating across 301 Google reviews, which tells you something about their track record with local customers.
Frederick's humid climate (averaging 69% relative humidity and 41 inches of rain yearly) makes mold a real concern, especially in older homes like many of ours here. The median house in Frederick was built in 1989, and moisture problems in foundations and crawl spaces are common. A typical remediation project runs $1500-$4650 depending on the scope. Before you sign anything with Mason-Dixon Restoration or anyone else, ask for their MHIC license number and verify it yourself online.
