Mobile home transport companies are not interchangeable, and the cheapest bid is almost never the one to take. A manufactured home move is a permitted, escorted, oversize-load operation governed by state and federal rules — not a flatbed rental with a tow hitch. The difference between a clean move and a stranded home on the shoulder of an interstate is whether the company holds the right credentials and files the right paperwork. Quartz Transport & Install runs that full stack — licensed and insured in NC and SC, registered under USDOT 3860134, with 40+ years of combined crew experience across two Carolinas hubs. Here's the checklist we'd hand a friend before they signed anything. Start from the basics on our mobile home transport overview.
The four credentials every legitimate company holds
First, a USDOT number — federal proof the carrier is registered to haul. Ask for it and look it up; a company that won't give one isn't operating legally for interstate or oversize work. Second, a set-up contractor license in the move's state: North Carolina issues a Manufactured Home Set-Up Contractor License, and South Carolina licenses through the LLR Manufactured Housing Board — because the move and the on-site set are regulated as one job, not two. Third, a commercial transport policy bundling general liability, cargo coverage, and workers' comp; ask for the certificate of insurance, because the home riding down the interstate is the cargo. Fourth, the ability to dispatch NCDOT-certified escort vehicle operators in-house. Any mover missing one of these four is quietly transferring that cost — and that risk — to you.
Who pulls the permits decides who carries the risk
The single clearest line between a full-service company and a haul-only outfit is permits. Every Carolinas move needs two filings. In North Carolina, the state-level oversize permit comes from NCDOT under the Publication MH-2 mobile and modular home permit, which fixes legal travel windows, escort-vehicle counts, and the approved route for a wide load on state highways. The county-level filing is the tax-paid moving permit issued by the county tax collector under NCGS Chapter 105, Article 18, confirming property taxes are current before the home leaves the parcel. In South Carolina, the move and the utility reconnect run under SC Code § 31-17-360. A company that hands you the permit application instead of filing it has just made the legal exposure yours. Quartz files all of them — see exactly what's required on our mobile home moving permit page.
Reading a quote: what cheap really means
Use the published cost bands as your yardstick. A single-wide in-state move runs $3,000–$8,000, a double-wide $7,000–$15,000, and a cross-state haul $5,000–$25,000. When one bid lands far under the rest, it's not a discount — it's a missing line item. The costs that vanish from lowball quotes are the mandatory ones: the MH-2 permit, the county tax-paid permit, certified escort hours, and re-leveling the chassis to a 1/4-inch tolerance with fresh anchors on the new pad. Ask every company to itemize permits, escorts, and setup separately, then compare. Our breakdown of mobile home movers prices shows what a complete, honest quote actually contains — so a hollow number can't pass for a bargain.
A good company inspects the home before it quotes
The best signal of a serious transporter is that they look at the unit before naming a price. Not every home is movable. A reputable crew walks the chassis, checks axles and tires, and flags rotted frames, soft floors, or a unit built before the 1976 HUD code — the federal manufactured-home construction and safety standard at 24 CFR Part 3280, Subpart G that the destination set-up inspection is measured against. A company that quotes sight-unseen is guessing, and a guess on an oversize load is how homes end up red-tagged on arrival. Before you spend a dollar, settle the threshold question with our guide on whether a mobile home can be moved — age, width, and condition decide it, and an honest transport company will tell you the answer even when it costs them the job.
