M.A.R.S. Environmental (Formerly Certified IAQ Professionals)

M.A.R.S. Environmental (Formerly Certified IAQ Professionals) carries a strong 4.9-star rating across 91 Google reviews, which matters in Arvada where older homes (median built 1979) and humid conditions (52% average relative humidity, 17" annual rainfall) create real mold risk. That track record suggests homeowners have found value in their work. If you're noticing signs of mold or just want peace of mind, a mold inspection typically costs $200-$600 in this area and can help you understand what you're dealing with before deciding on next steps.

Before you call, know that Colorado doesn't require a specific mold remediation license, so verify credentials carefully. Look for IICRC certification and confirm the contractor carries both general liability and pollution liability insurance. One important caveat: M.A.R.S. Environmental is listed as a mold inspector who also performs remediation work. Industry standards flag this as a potential conflict of interest, since the same company that inspects your home also profits from selling you the fix. Consider getting a second opinion from an independent inspector if you want an unbiased assessment.
