WQB Mold Removal partners with an independent accredited lab to give Grawn clients real, documented answers instead of a visual guess.
This service exists separately from inspection and remediation because sometimes all a Grawn client needs is a number — for an insurance claim, a real estate deal, or plain peace of mind. Our lab partner uses accredited methodology, which matters if your Grawn, MI results ever face scrutiny. We keep a copy of every report on file in case you need it again down the road.
Four reasons Grawn property owners trust us with this specific job.
We use an independent accredited lab for every Grawn sample, keeping results objective. Sample chain-of-custody is documented from collection through lab delivery.
Most Grawn jobs benefit from both methods together for a complete picture. We can rush results for Grawn clients working against a closing date or claim deadline.
Standard results typically return within a few business days of sample collection. Sample chain-of-custody is documented from collection through lab delivery.
Every result comes with a written lab report you can hand directly to an insurer, buyer, or contractor. We can rush results for Grawn clients working against a closing date or claim deadline.
Every Grawn job gets scoped to the specific problem, not a generic checklist.

Air pump cassettes capture airborne spore samples from indoor rooms and an outdoor control point for comparison.
A swab or tape lift from a suspect surface identifies the specific mold species present at that spot.
Environmental Relative Moldiness Index testing analyzes dust samples using DNA methods for a broader property-wide picture.
Testing before remediation establishes a baseline; testing after confirms the work actually brought levels back to normal.
An independent clearance test after remediation confirms the space is safe to reoccupy.
We'll walk you through what your results actually mean in plain language, not just hand you a page of species names.

Answers to what Grawn customers ask before booking mold testing.

Standard turnaround is typically a few business days from sample collection.
An inspection is a visual and moisture-based assessment; testing involves lab-analyzed samples with documented spore counts.
Some Grawn clients only want clearance testing after a visible problem was already treated — either approach is fine.
For the most accurate baseline, we typically recommend testing before any cleaning or remediation begins.
Our reports include the documentation most Grawn, MI insurers require — species ID, spore counts, and sampling methodology.
