What Quackenbush Mountain Resource 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.

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.

Order slightly over rather than under. Coming up short means a second delivery charge, which almost always costs more than the extra material would have.

Ordering and delivery

Delivery pricing usually keys off distance from the yard, so confirm both the charge to your address and any minimum load before comparing quotes.

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.

Ratings and reputation

Of the 63 reviews on file, 47 are five-star (75%) and 8 are four-star. 6 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 California, this rating places Quackenbush Mountain Resource in the top 71%.

Across the 8 suppliers we list in Clearlake, the average rating is 4.5.

Review volume matters as much as the score. A 4.5 drawn from 63 reviews reflects a substantial track record.

Hours and visiting the yard

Quackenbush Mountain Resource is open 6 days a week, closed on Sunday. The yard opens as early as 7:30 AM and runs until 3 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 California

California's longer growing season spreads demand across more of the year, which generally means better availability than northern markets. Even so, spring remains the peak for topsoil, and summer heat makes midday loading and installation punishing — early-morning pickups are worth the alarm clock. Autumn and winter are frequently the best value windows, with shorter queues and more flexible delivery scheduling.
