Adam Basement Waterproofing

Adam Basement Waterproofing carries a 4.8-star rating across 143 Google reviews, which matters in Wilmington where older homes (median built 1953) face real moisture challenges. With 67% average humidity and 44 inches of annual rainfall, basements here are vulnerable to water intrusion and mold. That strong track record suggests the company knows how to handle the specific conditions that plague decades-old houses in this area. If you're dealing with dampness or mold concerns, their experience in this climate is a practical advantage.

Before hiring, verify that Adam Basement Waterproofing holds a valid Delaware Contractors License from the Delaware Contractors Licensing Board and carries general liability insurance, since Delaware doesn't require a specific mold remediation license. Ask whether they hold IICRC S520 certification, which signals formal training in mold remediation. Typical projects in Wilmington run between $1,400 and $4,200, so get a detailed estimate in writing. One important note: don't assume any contractor's qualifications without checking these credentials yourself.
