Delivery and Shipping


BuildASoil Shipping Policy

Notice: Each product page displays accurate estimated delivery windows based on real-time fulfillment and carrier schedules.




Shipping Options

At checkout, you’ll be presented with the following options:

  • BuildASoil Shipping (Free)
     Our complimentary shipping method for qualifying orders. We choose the most cost-effective carrier and shipping method. Delivery may take up to 10 business days. Most items qualify when you purchase two or more eligible products. Some qualify individually.

  • Standard Shipping
     A paid option where we ship using standard ground services, without prioritizing fulfillment speed.

  • Standard Shipping: Rushed Out the Door!
     Includes everything in Standard Shipping, plus guaranteed same business day shipment if the order is placed before our cutoff time.

  • Get It Fast
     Our expedited service. Orders are shipped via 2–3 day methods and prioritized for fulfillment, with most leaving the same business day (not guaranteed).

  • Overnight It
     For urgent deliveries, this ships your order via overnight service with immediate fulfillment, within 24 business hours..

  • FedEx Freight (Economy or Priority)
     Large or heavy orders that qualify for freight shipping will be offered these options. All freight ships via FedEx Freight unless otherwise arranged. If you require a non-liftgate delivery (e.g. dock or forklift available), please contact us in advance.




Carriers Used

We primarily ship with FedExUPS, and USPS. If you need a specific carrier for a specific shipping address, please reach out to us by phone at 855-877-7645, or send us an email to support@buildasoil.com, which will create a customer support ticket. You also have the option of submitting a ticket through the support.buildasoil.com site.




PO Boxes

Orders addressed to PO Boxes often incur additional costs and are ineligible for free shipping. To avoid delays or fees, we recommend using a physical shipping address whenever possible.




Shipping Outside the Lower 48

We do ship to Alaska, Hawaii, Puerto Rico, Guam, the U.S. Virgin Islands, and other U.S. territories.
Free shipping does not apply to most large or bulky items sent to these locations. Standard or custom rates will be calculated at checkout. Contact us if you need a freight quote for outlying areas.




Vendor-Fulfilled Items

Some products ship directly from our vendor partners. These will display accurate estimated ship dates on their product pages. Any concerns or delays with these items should be directed to support@buildasoil.com.




Freight Shipments

Freight shipping involves delivery of pallets via box trucks or semi-trailers.
By default, all freight is assumed to require liftgate service. If you do not need a liftgate, please notify us prior to shipment.

Inspect your freight order before signing the delivery receipt.
Count the number of packages and check for visible or concealed damage. Do not sign unless everything is accounted for and undamaged. Signing a receipt waives the right to claim missing or damaged freight unless noted at delivery.




Order Tracking

Tracking information will be emailed to the address on file once the order ships.
If you do not see the tracking email, visit https://buildasoil.aftership.com/ to locate your order using your email and order number. You may also contact support@buildasoil.com for assistance.




BuildASoil Shipping Protection

You can add BuildASoil Shipping Protection at checkout. This low-cost option insures your order against loss, theft, and damage.
If something goes wrong during transit, your replacement order will be fast-tracked through our claims system.

Even when protection is purchased, we request that you submit photos, videos, and any supporting evidence of the issue. This allows us to file formal claims with carriers and ensure the long-term success of our shipping network.




Claims Policy

All claims must be made via support@buildasoil.com.
 We do not accept claim submissions via phone.

To process your claim, we require the following:

  • A clear description of the issue

  • Photos or videos documenting damage, missing items, or incorrect products

  • Images of packaging, shipping labels, and box condition if relevant

Do not discard any shipping materials or products involved in the claim—carriers may require inspection.

Claim Deadlines:

  • Visible or Concealed Damage / Missing Items: Report within 5 business days of delivery

  • Incorrect Products: Report within 30 days of delivery

  • Lost Packages or Incorrect Delivery: Report within 30 days of shipment date




Carrier Responsibility Disclaimer

Once an order has left our facility, BuildASoil is not responsible for carrier-related issues such as delays, misroutes, or mishandled deliveries.
We will support claims to the best of our ability, but the final resolution is subject to carrier approval.

Additionally, we maintain zero tolerance for mistreatment of delivery drivers, delivery dispatchers, or anyone with the shipping/freight carrier. Any reported conflict resulting in a failed delivery will result in the order being refunded, minus the cost of shipping and a 15% restocking fee.

Our best worm castings ever! 🌟 Check out the reviews below

Over 400 x 5-Star Reviews from growers just like you that decided they wanted to experience the best. 

Premium Worm Castings from a local family farm

🥇 Experience the pinnacle of compost quality with Colorado Worm Company's tea-grade, vermi-dynamic compost. Our ultra-premium, small-batch castings are packed with life, featuring a community of Red Wigglers, Predator Mites, Rove Beetles, and more. 🐛

-->GUARANTEED to start your Eco-System. Each bag will have different life, often with live Red Wigglers, Rove Beetles, and Predator Mites in the bag! 

(Watch The Video To Learn More About What To Expect)

These beneficial insects are safe and separately ordered can cost hundreds of dollars and they all come for FREE inside your bag of Colorado Worm Company Castings. Most companies cannot guarantee this because they repackage truckloads of worm castings that look like "Pure Castings" because the worm bedding is dark black sedge reed peat that looks like castings. Colorado Worm Company uses finished Farm Made Compost as their bedding source. This is the absolute best way to do this as taught by ClackamasCoot and many others.

👨‍🌾 Crafted with care on a family horse farm in Western Colorado, each batch of COWOCO vermicompost is a testament to our commitment to organic, high-quality soil amendments. We feed our privileged worms a rich diet of bio-dynamic, fully finished compost, native soils, and glacial rock dust. 🌾

🛡️ Guaranteed Performance: We're so confident in our castings that if they don't outperform your expectations, we'll offer a replacement bag or a full refund. Expect your castings to arrive moist, rich, and teeming with life, or we make it right!

  • 1 Cubic Foot = Approximately 40 lbs
  • 1/2 Cubic Foot = Approximately 20 lbs
  • 2 Gallon Bag = Approximately 10 lbs
  • 1 Cubic Yard = Approximately 1000 lbs

Application methods and rates:

🌼 Top-dress your flowerpots or raised beds with a generous two-inch layer every two weeks to one month during both veg and flower stages. For an extra phosphorus boost, aerate water and add our castings at a rate of 1:10 to water, brew for no more than 24 hours, and apply directly to the root zone for immediate results.

🌍 Eco-Friendly Production: Our operation boasts a minimal carbon footprint, utilizing only a modest tractor while maintaining a closed-loop system with our hardworking worms. 🚜

📢 YouTube Testimonial: "These were some of the finest worm castings that I have ever used. You definitely hit it out of the park with the superior quality, microbial life, and nutrient density." - Alex

Best value

This is the ultimate worm castings. It takes so much of the other brands to equal the benefits of one bag of cowoco. I will only use them. BAS is so great for finding all these wonderful companies for us. Thank you.
