Shipping & Delivery

Last updated · September 25, 2026

Here's how your kit gets to you, and how your sample gets back.

When your kit ships

Kits usually ship within 1–2 business days of your order. Orders placed on a weekend or holiday start on the next business day. We email you when your kit ships.

Cost and delivery time

• Standard shipping: $9.99 per order. It usually arrives 5–7 business days after it ships.
• Free shipping: when your kit subtotal is $500 or more, before discounts.

Delivery times are estimates, not guarantees.

Carriers

We ship kits by USPS or UPS.

Where we ship

We ship to addresses in the 50 U.S. states and Washington, D.C. We don't currently ship outside the United States, to U.S. territories, or to military (APO, FPO or DPO) addresses. If you're outside the U.S. and interested in our kits, email [email protected].

State restrictions

Some states regulate who may perform certain kinds of environmental testing, so some kits can't ship to some states and others need a short acknowledgment at checkout:

• Mold kits can't ship to Colorado, the District of Columbia, Florida, New Hampshire, New York or Texas. Orders to California and Oklahoma need an acknowledgment.
• Water kits ship everywhere we ship. Orders to New Jersey need an acknowledgment.
• Drug residue kits ship everywhere we ship. Orders to Alaska, Indiana, Kentucky and Minnesota need an acknowledgment.
• Allergen kits have no state restrictions.

Checkout applies these rules to your shipping address before you pay. Phone orders and kit requests through our website form follow the same rules: the same state restrictions and acknowledgments apply, you pay through a secure payment link from Stripe (we never take card numbers over the phone), and paying through that link means you accept our Terms. The full state-by-state details are in Terms §17, Regulatory disclosures.

Tracking

When your kit ships, we email the tracking number to the address you gave at checkout. Use it on the carrier's website to follow your package.

Sending your sample back

Every kit includes prepaid return shipping for your sample, so there's nothing extra to pay. Follow the instructions in your kit to pack and send it. Some samples need to travel quickly or cold, so send yours when the instructions say.

Delays, loss and damage

We're not responsible for delays caused by:

• carrier disruptions or capacity limits;
• weather, natural disasters or other events beyond our control;
• an incorrect or incomplete shipping address;
• package theft or loss after the carrier confirms delivery.

If your kit hasn't arrived within the estimated window, contact us and we'll help. If it arrives damaged, we'll replace it free; see our Refund & Return Policy.
