RTK Environmental holds a 5-star rating across 201 Google reviews. If you're dealing with mold in Norwalk, that track record is worth noting. Norwalk's climate - with 71% average humidity and 50 inches of annual rain - creates ideal conditions for mold growth, especially in older homes. Many houses here were built around 1966, and those structures are particularly vulnerable to moisture problems that can hide behind walls and under floors.
When you call RTK Environmental, ask whether their technicians hold IICRC S520 certification, which is the standard credential for mold work in Connecticut since no state-specific license exists. You'll also want to confirm they carry appropriate insurance. Typical remediation projects in this area run between $1600 and $4950, depending on the scope. Before you sign anything, verify that the company is registered with Connecticut's Department of Consumer Protection as required for home improvement contractors.
