RTK Environmental

RTK Environmental holds a 5-star rating across 205 Google reviews, which stands out given Danbury's challenging conditions for mold. The area's 72% average relative humidity and 47 inches of annual rainfall create ideal moisture conditions, and homes built around the median year of 1974 often have aging foundations and ventilation systems that compound the problem. That consistent rating suggests the company has earned trust from local homeowners dealing with real mold concerns in older properties.

Before hiring RTK Environmental, verify their credentials carefully. Connecticut requires home improvement contractors to register with the Department of Consumer Protection, so confirm that registration is current. Ask specifically whether they hold IICRC S520 certification and carry appropriate insurance. One important caveat: RTK Environmental is listed as a mold inspector, and industry standards flag a conflict of interest when the same company both inspects and performs remediation work. For this reason, consider getting a separate, independent inspection (typically $200-$600 in your area) before committing to any remediation contract.
