What Rocky Mountain Compost, Inc. supplies

Screened topsoil is the workhorse material for new lawns, raised beds and regrading work. Yards typically screen to ½" or ⅜" to pull out rocks, roots and clods, and many sell blended mixes that cut native soil with compost or sand to improve structure and drainage.

Ask which blend you are buying. Straight screened topsoil suits filling and levelling; a 50/50 or 70/30 soil-compost blend performs far better as a planting medium. Pure fill dirt is a different product entirely — unscreened, often clay-heavy, and meant for structural filling rather than growing.

Bulk mulch comes in hardwood, dyed, cedar, cypress and pine bark varieties. Bought loose by the yard it usually costs well under half the per-volume price of bagged mulch at a big-box store, which is why most repeat buyers switch to bulk.

Because Rocky Mountain Compost, Inc. carries several material lines, it is often possible to combine an order across products — soil, mulch and stone on one truck — rather than paying separate delivery charges to two or three different yards.

How much material you need

Topsoil is sold by the cubic yard. A cubic yard of topsoil weighs roughly 2,000–2,400 lbs depending on moisture, so a half-ton pickup safely carries about one yard.

As a rough guide: 1 yard covers about 100 sq ft at 3 in; 3 yards covers about 325 sq ft at 3 in; 10 yards covers about 1,080 sq ft at 3 in.

Measure your area and decide on depth before calling. Most yards will run the volume calculation for you and will flag when stepping up to a larger load actually lowers the price per unit.

Ordering and delivery

Confirm the delivery radius and fee early in the call. Two yards quoting similar material prices can land very differently once haulage is added.

Check where the truck can actually dump. Tandem trucks need overhead clearance and firm ground, and most drivers will not reverse across a soft lawn or a new driveway. If access is tight, ask whether they run a smaller truck or can leave the load at the kerb.

Pricing for bulk material is rarely published in full, since it moves with stock and season. The business website may list current products, but a phone call will get you a firm delivered number faster.

Ratings and reputation

Of the 67 reviews on file, 56 are five-star (84%) and 4 are four-star. 5 reviews sit at one or two stars, and those are worth reading directly — complaints at material yards usually concern delivery timing or short loads rather than the product itself.

Among the suppliers we list across Montana, this rating places Rocky Mountain Compost, Inc. in the top 74%.

Across the 17 suppliers we list in Billings, the average rating is 4.7.

Review volume matters as much as the score. A 4.6 drawn from 67 reviews reflects a substantial track record.

Hours and visiting the yard

Rocky Mountain Compost, Inc. is open 6 days a week, closed on Sunday. The yard opens as early as 8 AM and runs until 5 PM.

Saturday opening makes this a practical option for weekend projects — a real advantage, since plenty of bulk yards shut for the weekend and leave homeowners unable to collect material outside working hours.

Loading is weather-dependent whatever the posted hours say. Heavy rain turns yards to mud and makes wet material heavier and harder to spread, so call the same morning if conditions look poor.

Best time to buy in Montana

In Montana, the buying window is compressed. Yards get busiest from the first thaw through early June, and again briefly in autumn. Ordering topsoil in early spring often means waiting in a queue and paying peak rates, so booking delivery before the rush — or in late autumn for spring work — usually gets both a better price and a firmer delivery date. Many yards in colder states reduce hours or close outright through deep winter, so confirm seasonal availability before planning a January or February project.

Bulk material pricing is intensely local. Trucking is a large share of the delivered cost, which is why a nearby yard usually beats a cheaper one further out once the full quote lands.
