When a contractor has 143 Google reviews at 4.8 stars, that's a solid track record - but it doesn't tell you everything. High review counts show the business has been around and done enough work to build a reputation, yet they don't guarantee the contractor is right for your specific situation. That's why it matters to verify credentials before you hire. In Wilmington, Delaware doesn't require a specific mold remediation license, so look for a contractor licensed by the Delaware Contractors Licensing Board with general liability insurance. Adam Basement Waterproofing should also carry IICRC S520 certification, which signals real expertise in mold remediation.
Wilmington's climate - averaging 67% relative humidity and 44 inches of rain yearly - creates ideal conditions for mold, especially in older homes like the median house built in 1953. Most remediation projects in this area run between $1400 and $4200, depending on the scope. Before you sign anything with Adam Basement Waterproofing, ask to see proof of their Delaware Contractors Licensing Board license and general liability insurance certificate.
