Long Distance Moving - All Service Moving
Long Distance Moving - All Service Moving
Long Distance Moving & Storage. Household, Commercial, International, Corporate services available. Our Mission is To exceed expectations on every move. We live this day in and day out. Our service is top notch and fully efficient. Our trucks are perfectly equipped for moving with Pads, dollies, Plastic and much more. We provide Long Distance Moves across the entire country, directly from our West Coast HUBS located in AZ, CA, OR and WA. Or, we team with our partner companies to complete moves together. We are proud to provide a service that no other company offers; Dedicated Trucks. This means that your belongings are loaded on the truck and not combined with anyone else’s items (from/to west coast only). They are not transferred to other trucks or facilities in route which causes damage and loss of items (typical with van lines). We have a set loading day and unloading day. This is by far the safest way to ship. Our interstate rates are per 24ft moving van that holds up to 8,500lbs or 1400CuFt. Some customers require one truck and some require more. One truck holds the average 1800SqFt.
"I cannot say enough great things about All Service Moving—and ESPECIALLY Rico and Reyes, who were absolute lifesavers for my last-minute move. After another moving company bailed on me the day before my scheduled move, All Service swooped in and saved the day. Rico and Reyes showed up EARLY, upbeat, and ready to tackle the challenge—even with super heavy furniture that usually requires a 4-person crew. Somehow, the two of them handled everything like pros without a single scratch or ding—on the furniture or either home. What really stood out was how personable, kind, and thoughtful they were. They moved quickly and efficiently, knowing I was paying by the hour, but never once sacrificed care or quality. They were kind to my mom (who was helping me out), and so sweet to my two dogs too. If you’re planning a move, ask for Rico and Reyes by name. They went above and beyond, and I want their team to know what a fantastic job they did. They deserve every bit of recognition. 100% recommend."
