Why an independent tester

A company that sells you the fix has a reason to find a problem. We only ever sell the answer.

01

No conflict of interest

We don't perform remediation, so there's no incentive to inflate a result. What the lab finds is what you get.

02

Lab-verified results

Samples are analyzed by an accredited third-party laboratory — not eyeballed on-site or self-graded.

03

Reports you can actually use

Every report comes with a plain-language walkthrough, so you know what the numbers mean before you make a decision.

04

Built for real estate timelines

Fast scheduling and clear turnaround times for home purchases, refinances, and pre-listing peace of mind.

What we test

Testing built around how mold actually moves through a home.

Every inspection is scoped to the property — not a one-size-fits-all checklist.

Air Quality Sampling

Spore-trap air samples taken indoors and compared against an outdoor control to identify elevated levels.

Surface & Swab Testing

Direct sampling of suspect growth on walls, wood, or HVAC components to confirm species and extent.

Pre-Purchase Home Testing

Independent results for buyers, sellers, and agents — scheduled around inspection contingency deadlines.

Moisture & Humidity Mapping

Moisture meter readings across likely trouble spots to identify the conditions feeding growth, not just the growth itself.

Post-Remediation Clearance

Independent verification testing after remediation work, confirming the space is genuinely clear before you move back in.

Report Walkthrough

A plain-language call to review your results, what the numbers mean, and what questions to ask a remediation company.

New England-rooted, testing-focused.

We built Bay State Mold Testing around a simple idea: a homeowner deserves an answer they can trust, from a company with nothing to gain from the result. That's why testing is the only thing we do.
