Double wide mobile home transport is not "a bigger single-wide move" — it is the controlled disassembly, paired oversize haul, and field re-assembly of a home that was built in two sections and joined at the factory. Quartz Transport & Install runs these moves across North Carolina and South Carolina from two dispatch hubs, Asheville/Fairview and Florence/Lydia, with crews carrying 40+ years combined on multi-section homes. Everything below describes what actually happens to your home between the day we quote it and the day it sits level on its new pad — because the work, not the marketing, is what determines whether the doors still close and the roof still sheds water afterward.
Splitting the home: the marriage line is the whole job
A double-wide arrives as two mirror halves bolted together along a centerline seam — the marriage line. Our first task on a transport is to reverse that join cleanly: unbolt the matched walls, separate the ridge beam and floor decking without tearing the gypsum, and brace each open side so the section keeps its shape on the road. Done carelessly, a split racks the frame and you spend the re-set chasing cracked drywall and binding doors. Done right, the two halves come apart along a line the factory engineered for exactly this, and the home travels in two pieces that re-marry within an eighth of an inch. The same discipline carries into our modular home transport work, where multi-module homes can split into three, four, or more sections that all have to true back up on site.
Two 14-foot loads: chassis, axles, and the toter haul
Once split, each half is its own oversize load riding on the original steel I-beam chassis it was framed on. Before either section leaves the lot, the crew inspects that chassis for rust and sag, re-shoes the axles with road-rated tires, and couples a hydraulic toter truck that lifts and steers the section out of the yard. At 14 feet wide, each half exceeds the legal lane on its own, so both sections move under separate NCDOT Publication MH-2 oversize permits with their own approved routing and daylight windows. NC pins wide loads to a 9:00 AM–2:30 PM movement window and prohibits travel in gusts over 25 mph, so a double-wide is two permitted, escorted runs — often staged a day apart when the destination pad can only receive one half at a time.
Escorts and permits: paired, not shared
Because the two sections never share a permit, they never share an escort schedule either. Each 14-foot half rolls with NCDOT-certified front-and-rear escort vehicles that clear intersections, manage low utility lines, and hold traffic on the tight stretches. Behind the road permits sits the paperwork that lets the home leave the parcel in the first place: a county tax-paid moving permit under NCGS Chapter 105, Article 18 in North Carolina, confirming the unit's taxes are current. A South Carolina move runs each section under a county permit per SC Code § 31-17-360, with the treasurer's tax-paid certificate attached. Quartz pulls every one of these for you, in both states — a cross-state NC↔SC double-wide stacks a second state's permit and escort rules on top, which is precisely the seam where unlicensed haulers get a load impounded.
Re-marrying, leveling, and anchoring on the new pad
The set is where transport becomes a finished home again. The crew positions both sections over the pad, blocks each half on piers, and levels to a quarter-inch tolerance across the full footprint before the marriage-line bolt-up begins. Then the two halves are drawn together, lag-bolted along the matched walls, and the ridge cap and floor seam are re-sealed so the envelope is weather-tight again. Finally the home is tied down to the destination's wind requirements under HUD 24 CFR 3280, Subpart G — frame-tie and over-the-top straps to auger anchors, sized to the site's HUD Wind Zone (most of the Carolinas piedmont and mountains sit in Zone I at roughly 70 mph, while coastal SC counties fall in Zone II near 100 mph and need the heavier strap schedule). That full mobile home setup is included in the transport quote, so one crew owns the home from split to set.
What it costs and what's included
In-state double wide mobile home transport runs $7,000–$15,000 in the Carolinas, with most jobs landing $10,000–$13,000 once setup is folded in, and a cross-state move reaching $15,000–$25,000 — roughly double the price of single wide mobile home transport because the permit, truck, escort, and set-and-anchor lines are each duplicated before the marriage-line re-bolt is added on top. That single number covers the two MH-2 permits, the county moving permit, both certified escort assignments, the haul of both sections, the marriage-line bolt-up, quarter-inch leveling, and re-anchoring. Utility disconnect/reconnect by licensed trades, a poured footing if the pad isn't ready, fresh skirting, and a HUD data-plate replacement are billed separately and flagged up front.
