Our Sand Lake, MI technicians sample near supply and return vents specifically, which a standard single-room test would never catch.
Every result comes with a plain-language walkthrough connecting the data back to what you're actually experiencing at home. We'll also suggest a sensible next step, whether that's duct cleaning or a physician conversation.
Four reasons Sand Lake property owners trust us with this specific job.

We don't process our own samples — an independent lab handles every Sand Lake analysis, keeping results unbiased. You can verify the lab's accreditation directly if that matters to you.

Reports include actual spore counts and species data, not a vague pass or fail. We're glad to explain the numbers directly with you over the phone.
