Facility info

OPERATIONS Appointments required; don't show up without one. Next available often 5+ days out Receiving opens 4am, typically start unloading early if you're there Unloading speed inconsistent: 30-45 minutes common, but also reports of 3.5+ hours and full-day waits Two separate locations cause confusion (1200 Lebanon vs 920 Irwin Run Rd / off-site warehouse) — confirm address with broker beforehand Heavy lumper fees ($500-$795) plus late fees ($500) charged aggressively; watch your invoice Some reports of paperwork mishandling and no phone support for directions FACILITY EXPERIENCE No overnight parking at facility; street parking available near GetGO gas station one block away (side of building, against curb) or nearby car wash No bathrooms Staff attitude mixed: many describe dock workers as pleasant and efficient, but some report rudeness, unprofessionalism, and selective treatment Building dirty and not handicap compliant per some reviews Receiving office between doors 6 and 1 BACKING/LOCATION Extremely tight, hilly terrain with steep grades — not for inexperienced drivers Narrow roads, low clearance bridge (13.5'), sharp turns Approach from Noble Rd, make wide right turn using left lane; don't miss turn or end up on Irwin Run Rd Backing requires good clutch/brakes and potentially locking inter-axle differential due to incline Manual transmissions handle better than automatics Receiving is between buildings; dock is doors 1-6 (refrigerated) BOTTOM LINE Fast unloading when it happens, but wait times unpredictable Aggressive fee structure; clarify all charges upfront Difficult terrain and confusing location — experienced drivers only Confirm exact address and appointment status before arriving
