Call most mold companies and you'll reach a remediation crew that profits from whatever they find. We don't do removal — so we have nothing to sell you but the facts: lab-verified answers, sampled at home, analyzed by real scientists, and explained in plain English. No upsell.
A few quick questions and we'll recommend exactly which samples to order — based on what you're actually seeing in your home.
Untested mold doesn't go away — it spreads. The longer it sits, the more damage it does to your home, your furniture, and your family's health. And the bigger the eventual remediation bill becomes. The homeowners who wait the longest pay the most.
The good news: catching it early is fast, affordable, and easy. ↓
Every kit follows the same rigorous process a professional laboratory uses. Here's exactly how your sample becomes a clear answer.
A calibrated pump draws a measured volume of air through a spore-trap cassette — capturing exactly what's floating in your home.
Your sample is examined under a microscope — the industry-standard method — and spores are counted against that known air volume.
A master's-level scientist and Council-Certified Microbial Investigator identifies what's present — down to the genus level.
You get spore counts compared to an outdoor baseline, what they mean, and prioritized next steps — in language anyone can read.
Optional: add a one-on-one consultation and talk through your results with a scientist who has 10+ years of experience — straight answers and clear next steps, never a sales pitch.
No upsells. No mystery fees. Choose the level of help that fits — add samples or consultation only as you need them.
Sample your home in 30 minutes with our expert-designed kit. Mail it back, and lab-verified results land in your inbox a few days later.
Real testing, real answers, and real expert guidance. Get your kit, your lab report, AND a one-on-one call with a scientist who walks you through exactly what to do next.

Why not a $30 store kit? A petri dish is read by no one — it just grows whatever lands on it and always looks scary. Our kits are analyzed under a microscope by a master's-level scientist with 30 years of experience. You're not paying more for a box; you're paying for an answer you can trust.

Not a scary petri dish. Actual spore counts, measured against an outdoor baseline, with exactly what they mean for you.
| Organism | Indoor | Outdoor | Status |
|---|---|---|---|
| Cladosporium | 320 | 410 | Normal |
| Aspergillus / Penicillium | 1,240 | 90 | Elevated |
| Basidiospores | 110 | 140 | Normal |
What this means: Aspergillus/Penicillium indoors sits far above your outdoor baseline — a sign of an active indoor source worth addressing. Everything else is within a normal range.
Healthy indoor air should track below the outdoor control. One organism here clearly doesn't.
See What Your Report Reveals →No more guessing. No more mystery symptoms. No more wondering if that musty smell is "just the season." Just clear, lab-verified answers — and a path forward you can actually act on. That's the relief our customers feel when their report lands in their inbox.
"I'd been dealing with sinus issues for years and finally tested. Turned out we had elevated Aspergillus in the bedroom. The report was so clear my contractor knew exactly what to do."
"Way more useful than the petri dish kit I bought first. The 30-minute consultation was worth every penny — they walked me through exactly which spots to remediate first."
"After a basement flood I needed real answers. The kit arrived fast, sampling was easy, and the report was honest — they told me what was concerning AND what was just background."
Most at-home tests are sold by companies that never see your sample. With Now Mold Testing, an experienced microbial investigator personally analyzes every kit. We're a small, expert-led team — and that's the whole point.

Once your kit reaches our lab, results typically take 3-5 business days. You'll get an email when the report is ready. The whole timeline from order to report is usually 7-14 days, depending on shipping.
Air cassettes use a small pump to capture spores floating in your air — great for understanding overall room air quality. Tape lifts press onto a surface to capture mold growing right there — perfect for pinpointing a specific spot you can see. Most situations call for both.
Petri dish tests grow whatever airborne mold lands on them, which means they always show "mold detected" — even in perfectly healthy homes. Our kits use industry-standard cassettes that capture a measured volume of air, analyzed under a microscope by certified investigators. The result is a real, comparative answer, not a scary-looking dish.
If you want to know what's there, the kit alone is enough — every kit comes with a written report and recommendations. If you want help deciding what to do based on the results (or you have a complex situation), the consultation pairs you with a scientist who walks you through your specific case.
Take the free quiz on our home page — it recommends the right kit for your situation in under a minute. Most people know exactly what to order without needing to reach out at all.
Unused kits in their original packaging can be returned within 30 days for a full refund. Just contact us before mailing it back.
