What Cornerstone Landscape Supplies Inc. supplies

Full-line landscape supply yards stock soil, mulch, decorative stone, boulders, pavers, edging and often sod under one roof. That matters when a project needs several materials, because combining them into a single delivery avoids paying separate trip charges to multiple suppliers.

Loose material is normally priced by the cubic yard while stone is priced by the ton, so compare quotes carefully — the two units are not interchangeable and a cheap-sounding per-ton price can work out dearer.

Aggregate yards carry crushed stone, pea gravel, road base, mason sand, concrete sand and structural fill. Material is graded by particle size, and the correct grade depends entirely on whether you are building a compacted base, a drainage layer or a walking surface.

Because Cornerstone Landscape Supplies 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

Landscape materials is sold by the cubic yard. Delivery vehicles vary; a tandem dump truck carries roughly 10–12 yards, while smaller trucks top out near 5.

As a rough guide: 1 yard covers about 100 sq ft at 3 in; 5 yards covers about 540 sq ft at 3 in; 15 yards covers about 1,620 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.

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.

Hours and visiting the yard

Cornerstone Landscape Supplies Inc. is open 6 days a week, closed on Sunday. The yard opens as early as 6:30 AM and runs until 4 PM, early enough to load before a normal work day begins.

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 Massachusetts

In Massachusetts, the buying window is compressed. Yards get busiest from the first thaw through early June, and again briefly in autumn. Ordering landscape materials 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.
