FAQ

Can you help me figure out what material I need for my project?

Absolutely — free material consult is part of how we work. Send your project details (type, area, depth, end use), and we'll recommend the right material and quantity, no purchase required. Most consults are answered within a few hours by call, text, or email.

What to send for the fastest answer

  • Project type — "new lawn install," "driveway base layer," "mulch refresh on existing beds," "raised bed fill," "French drain backfill," etc.
  • Area dimensions — length × width in feet (or square feet if you have it). Sketch with a photo also works.
  • Depth needed — how deep you want the material (3" mulch refresh? 4" driveway top coat? 12" raised bed?)
  • Surface or use case — is this going on lawn, garden bed, driveway, walkway, slope?
  • Special considerations — pet-safe? acid-loving plants? heavy traffic? coastal salt exposure?

How we respond

  1. Recommended material(s) — sometimes one product, sometimes a base + top combo (e.g. dense pack + crushed stone for driveway)
  2. Cubic yardage estimate — calculated from your dimensions and depth
  3. Coverage math — we show the calculation so you can verify
  4. Delivery cost estimate — based on your ZIP
  5. Order link — if you want to proceed, direct link to the product page with quantity pre-set

Common project recommendations

  • Mulch refresh on existing beds: Hemlock or Pine Bark, 2–3" depth. Cover ~100 sq ft per cubic yard.
  • New driveway: Dense Pack base layer 4–6" + Gray Crushed ¾" top coat 2–4".
  • Lawn repair / regrade: Topsoil ½" Screened, 3–4" depth, then seed.
  • Raised garden bed: Garden Soil Mix or Super Loam, full depth of bed (typically 12").
