RTK Environmental

RTK Environmental holds a 5-star rating across 201 Google reviews, which matters in Norwalk where homes built around 1966 face real moisture challenges. The area's 71% average relative humidity and 50 inches of annual rainfall create ideal conditions for mold growth in older structures. When you're dealing with a potential mold problem, that consistent rating suggests homeowners in your situation have had reliable results calling this mold remediation contractor. Typical projects in Norwalk run between $1,600 and $4,950, so you'll want a contractor you can trust to assess the scope accurately.

Before hiring, verify that RTK Environmental is registered with Connecticut's Department of Consumer Protection, as the state requires all home improvement contractors to hold this registration (note that Connecticut doesn't issue a specific mold remediation license). Ask whether they hold IICRC S520 certification and confirm they carry appropriate insurance. One important caveat: get a detailed written estimate upfront that specifies the affected areas and remediation scope, since costs can vary significantly based on how extensive the mold damage turns out to be.
