Quick Answer
Pre-winter rock salt pricing for Cohasset and the South Shore is holding flat versus 2024, with Untreated Rock Salt at parity and Treated Rock Salt up 3–5% on calcium-chloride input costs. Salt-sand blends (50/50 and 20/80) are essentially flat. The Cohasset-specific story: lead times are still tight on small orders (under 2 yards) because of the coastal-property volume from Atlantic-exposed driveways. Pre-book by November 25 to lock the November rate before December's storm-watch premium.
What's Driving the 2025–2026 Pricing
Three factors shape salt pricing across the South Shore this November:
1. Quarry-side stable. The northeast rock salt supply (Maine and upstate NY mines) is healthy. No supply-chain shock like 2014 or 2018.
2. Trucking costs flat. Diesel pricing has eased; freight from the Brockton bulk yard to Cohasset runs the same as last winter on a per-yard basis.
3. Calcium chloride brine up. Treated salt — sodium chloride pre-blended with calcium-chloride brine for sub-15°F effectiveness — sees the only real bump, around 3–5% per cubic yard.

Cohasset-Specific Demand Notes
Cohasset's residential profile is unique on the South Shore: heavy coastal exposure, longer-than-average driveways (gravel and asphalt), and irregular street-plow coverage in the winding harbor neighborhoods. That drives three demand patterns Ottr is tracking this November:
- Salt & Sand 50/50 is moving heavier than usual — Cohasset's shaded coastal driveways ice over and stay icy, where the 50/50 blend's traction component matters more than pure melt
- Mason Sand alone demand is up 8% year-over-year as homeowners protect old concrete and coastal-saltbox brick walks from chloride exposure
- Untreated Rock Salt demand for the central drive remains the workhorse — flat year-over-year

Lead Times This Week
- Standard residential delivery to Cohasset: 3–5 days
- Standard contractor route delivery: 2–4 days
- Storm-watch week (forecast 7-day): 7–10 days
- Forecast 3-day storm window: delivery may not happen before the storm
The November 25 pre-order deadline isn't arbitrary — once the National Weather Service flips on the first Winter Storm Watch, the demand spike compresses lead times to a week-plus.
What Cohasset Contractors Are Doing
Talking to Cohasset snow-removal operators this week, the prep cadence looks like:
- Bulk yard load-out by November 22 for primary fleet stocking
- Smaller residential top-off orders mid-December to cover post-first-storm
- Salt-sand bin builds at homeowner sites for premium accounts

Coastal Considerations Specific to Cohasset
Two Cohasset-specific factors worth flagging:
Salt spray + applied salt = compounding lawn damage. Cohasset's harbor-adjacent properties already receive natural salt spray from Atlantic storms. Adding heavy-rate rock salt to the curb edge multiplies the damage. The right call for Cohasset coastal lawns: Salt & Sand 20/80 at the lawn-edge strip, plus mason sand alone for the last 2 feet against any planting bed.
Older concrete vulnerability. Many Cohasset Center and Cohasset Harbor walks are pre-1970 concrete with shallow rebar. Aggressive chloride exposure accelerates rebar corrosion. Lower-chloride blends save the concrete.

Pre-Order Window Closing Soon
The November pre-order window for Cohasset closes practically on November 25. Orders placed after that date roll into December storm-watch pricing — typically 5–10% higher and with longer lead times.
Three call-to-actions for this week:
- Calculate your seasonal need — see How Much Rock Salt Do I Need for a Roslindale Driveway This Winter?
- Pick the blend based on driveway exposure and lawn-edge risk
- Book delivery by November 25 to lock current pricing
