How BioDwell works

A lab result is half the answer. We send the other half.

  1. 01

    Pick the right test

    Tell us what's going on — a musty smell, a well that hasn't been checked, a buyer's due-diligence window — and we point you to the right kit. Five categories, one decision.

  2. 02

    Collect at home

    The kit ships with guided instructions and a pre-paid return mailer. Most samples take 5 minutes to collect. Drop the sealed kit at any post office.

  3. 03

    Reviewed by a scientist

    The lab returns the raw data. It goes through the BioDwell Scientific Review, and you receive a written report — what was found, what it means for your home, what to do next.

What we test

7 tests

Mold & Mycotoxins

Dust panels for whole-home screening, air cassettes for individual rooms, surface swabs for visible growth. Results come back with species identification and amounts. We explain what they mean and what to do next in plain, common-sense language.

7 tests

Water Contaminants

PFAS, microplastics, heavy metals, volatile organic compounds, radiological substances, glyphosate, and other contaminants of concern. We test water from your home, whether it's city water or a private well.

Shop water
4 tests

Drug Residue

Surface testing in your home, rental, or investment property for methamphetamine, fentanyl, and up to 15 other substances. Test for one or test for all — for pre-purchase due diligence, post-eviction verification, tenant safety, or peace of mind. You receive easy-to-understand reports with the relevant threshold (acceptable) values.

5 tests

Common Allergens

Indoor allergen panels for dust mite, cat, dog, cockroach, and select pollens. Best paired with a documented sensitivity — the numbers help match interventions to actual exposure rather than guessing across the list.

Where we operate from

Who we work with

Testing for one home or many.

Same kits, same accredited labs, same scientific review. Households buy one and we ship it.

Household

Persistent symptoms in one room, a leaky basement, an older home you just moved into. Pick a test, collect at home, and get a written read on what's actually there.

Find your test →

Property teams

Pre-tenancy verification, post-eviction documentation, and recurring testing across multiple units. Get in touch and we'll help you set it up.

Get in touch →

Real-estate & pre-purchase

Buyers, sellers, and agents using environmental testing inside an inspection window. Single-home kits, expedited turnaround when a deadline is in play, and a written report that lands before the contingency closes.

The last step

Stop guessing about your home.

Pick a test, collect a sample, and let the lab data come back with context. The numbers without interpretation are just numbers.
