Underpinning for a mobile home can mean enclosing the space beneath it with skirting, or adding structural support to a settling home; the two jobs have very different prices. Typical skirting installation runs about $1,500-$5,000, while structural underpinning and foundation repair often cost $3,000-$15,000 or more, depending on home size, materials, access, and the amount of leveling required.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Vinyl skirting installation | $1,000 | $2,500 | $4,500 | Material and labor for a typical single-wide |
| Metal or insulated skirting | $2,000 | $4,000 | $7,000 | Higher-grade panels and trim cost more |
| Structural underpinning | $3,000 | $8,000 | $15,000+ | Supports, leveling, and site conditions determine scope |
| Skirting price per linear foot | $10 | $25 | $50 | Installed; varies by material and preparation |
Assumptions: U.S. contractor pricing, standard access, and no major soil remediation or extensive utility relocation.
What mobile home underpinning typically costs
For a basic enclosure, budget roughly $1,500-$5,000; for structural support work, expect approximately $3,000-$15,000 or more. These are different scopes, so an estimate should say whether it covers skirting, load-bearing supports, leveling, or a combination. Skirting encloses the underside but does not correct a settling foundation or replace the home’s support system.
A 14-by-70-foot single-wide has about 168 linear feet around its perimeter before subtracting door openings. At $10-$50 per installed linear foot, that works out to roughly $1,700-$8,400; standard vinyl work often lands toward the lower portion of that range. A 28-by-70-foot double-wide has about 196 perimeter feet, though seams, corners, and access details can add labor.
Structural underpinning is quoted by the extent of the repair rather than by perimeter length alone. A few replacement piers or support adjustments may cost several thousand dollars, while extensive leveling, new footings, engineering, or difficult excavation can push a project above $15,000. Home size, material choice, soil, and whether the structure needs lifting are major pricing assumptions.
How panels, labor, and support work appear on the quote
Skirting quotes mostly reflect panels, framing or track, installation labor, and access details; structural quotes instead emphasize supports, lifting, and foundation work. The table shows common budget categories. Not every contractor separates these items, so ask whether the price is a fixed installed total or an allowance that could change after work begins.
| Quote item | Typical price range | What changes the charge | Common unit |
|---|---|---|---|
| Vinyl skirting materials | $3-$12 per linear ft | Panel thickness, color, trim, and vents | Linear foot |
| Metal or insulated panels | $8-$25 per linear ft | Finish, insulation, framing, and custom cuts | Linear foot |
| Skirting installation labor | $5-$20 per linear ft | Ground preparation, corners, and obstacles | Linear foot |
| Leveling or support adjustment | $500-$3,000 | Number of supports and degree of correction | Small repair |
| New piers or footings | $300-$1,000 per support | Type, depth, equipment, and soil conditions | Per support |
| Removal and disposal | $200-$1,200 | Old material, debris volume, and disposal fees | Project total |
Labor for skirting may be included in an installed per-foot rate or listed separately at approximately $50-$100 per hour. Structural crews may use a project price because lifting and support work depend on load, access, and safety setup.
Allowances can cover vents, access panels, fasteners, and trim. Ask whether the quote includes a ground-level clearance, removal of existing panels, cleanup, and any required inspection. A low materials-only price is not directly comparable with a complete installation.
How home dimensions and panel material change the price
Perimeter, not just square footage, drives skirting quantities, while support work depends on the home’s weight and existing foundation layout. A rectangular 14-by-70-foot single-wide has roughly 168 perimeter feet; a 16-by-80-foot home has about 192 feet. If installed skirting costs $15-$35 per linear foot, those examples imply about $2,500-$5,900 and $2,900-$6,700, respectively, before unusual site work.
Vinyl is usually the lowest-cost choice and may be appropriate where appearance and basic enclosure are the priorities. Metal panels commonly cost more and can provide a more durable finish, depending on gauge, coating, and installation. Insulated systems increase the initial price and are not automatically necessary; local climate, moisture management, and the home’s construction affect whether insulation makes practical sense.
Structural scope can rise sharply when supports are badly out of level, damaged, or insufficient. A small adjustment to a few supports might stay below $3,000, while adding or replacing multiple piers can add hundreds of dollars per support. If the home needs to be lifted, the contractor may need specialized jacks, careful sequencing, and additional labor.
Soil and access also matter. Soft or unstable ground, a steep grade, standing water, buried obstructions, and limited clearance can require extra preparation or equipment. A contractor should identify what is included in the estimate and flag conditions that could trigger a change order.
What three mobile home underpinning quotes might include
Comparing equivalent scopes makes a quote more meaningful than comparing totals alone. These examples illustrate plausible U.S. project budgets, not guaranteed local prices. Regional labor rates, required permits, and site conditions can move the final amount.
| Example scope | Approximate calculation | Estimated total |
|---|---|---|
| Single-wide, basic vinyl skirting | 168 linear ft at $18-$28, plus $250-$600 for vents and access details | $3,300-$5,300 |
| Single-wide, insulated skirting with old panels removed | 168 linear ft at $30-$45, plus $500-$1,200 removal and prep | $5,500-$8,800 |
| Localized structural repair | 4-8 supports adjusted or replaced, plus leveling and crew time | $3,000-$8,000 |
For the basic skirting example, a two-person crew might need 10-18 hours if the ground is reasonably level and the perimeter is clear. The insulated replacement example may take 16-30 hours, especially if old panels are damaged or fastening surfaces need repair. Structural work may require a site inspection before a firm schedule or price is available.
Ask each bidder to list home dimensions, material type, linear footage, number of supports, removal, disposal, and any exclusions. A quote that uses an estimated perimeter should explain how it will be adjusted if measurements differ.
Why regional labor and local rules affect the estimate
Labor markets and local requirements can shift a mobile home underpinning quote even when the home and materials are similar. In higher-cost metropolitan areas and parts of the Northeast or West Coast, installed prices may be 15%-30% above a national midrange. Rural markets may be 5%-20% lower, but longer travel distances or a shortage of qualified crews can erase that difference.
Weather and climate influence material choices and the need for ventilation or insulation, but local rules should guide the specification. Requirements for skirting, crawl-space access, ventilation, wind resistance, and foundation anchoring vary by jurisdiction and property type. A local building department or qualified contractor can confirm whether a permit or inspection applies to the planned work.
Structural changes may have additional review requirements, especially if the scope changes the support system or involves substantial lifting. Budget for a possible permit or inspection charge of $50-$500, where applicable, and ask whether engineering is required. Engineering or plan preparation can add several hundred to more than $2,000 for a complex repair.
Before accepting a low quote, verify that the contractor is pricing the same material, installation method, and code-related work as other bidders. In communities with park rules, the property owner or park manager may also require approval for panel color, access, or construction timing.
When removal, drainage, and access add charges
Hidden preparation and site work can add hundreds or several thousand dollars beyond the panel price. Removing old skirting commonly costs $200-$1,200, depending on its condition, fastening method, and disposal distance. Damaged material, animal contamination, or debris beneath the home may require separate cleanup and should be itemized.
Uneven ground may require grading or a lower panel course to close gaps correctly. Minor leveling or preparation may add $200-$800; more extensive grading or drainage correction can cost $1,000-$4,000 or more. Standing water should not simply be sealed behind new panels, since poor moisture control can create problems beneath the home.
Plumbing lines, electrical wiring, gas connections, HVAC ducts, and support piers can limit where panels or access doors go. Moving or repairing utilities is generally outside a basic skirting quote. Require written approval before extra work begins and request a separate estimate for any utility or drainage correction.
Structural support work can also uncover concealed damage or unsuitable soil. Ask the contractor to specify which conditions are included, how unexpected repairs will be priced, and whether work will stop for approval if the scope changes. A contingency of 10%-15% is reasonable when site conditions are not fully visible.
How repair compares with replacement or upgraded skirting
Repairing a small damaged area is usually less expensive than replacing all the skirting, but it will not solve a structural problem. Replacing a few loose or cracked panels may cost $200-$800, including a service visit. A full vinyl installation on a typical single-wide commonly falls around $2,000-$4,500, with dimensions and access affecting the total.
Metal or insulated panels can make sense when the existing system is deteriorated or when the project has specific durability or thermal requirements, but the higher initial cost should be compared with the expected use and maintenance. A premium system may bring a single-wide project to $4,000-$7,000 or more. It does not substitute for proper ventilation, moisture control, or load-bearing supports.
DIY installation can reduce labor charges, but accurate measuring, ground clearance, fastening, vent placement, and utility access matter. Material-only costs may start around $3-$25 per linear foot depending on product. Structural lifting or pier work is a different safety and engineering task; it should not be treated as a simple skirting project.
If the home is settling, obtain a foundation or leveling assessment before buying new panels. Installing skirting first can mean paying to remove or cut it again during support repairs. Confirm whether a contractor’s structural quote includes reinstalling any panels that must be disturbed.
Ways to control the final mobile home underpinning bill
The clearest savings come from defining the scope, preparing the site, and comparing complete written bids. Measure the perimeter and record the number of doors, corners, vents, and obstacles, but have the installer verify dimensions before ordering. Specify whether the request is for enclosure, structural support, or both.
Choose a material based on actual needs rather than assuming the most expensive option is necessary. Compare installed totals for standard vinyl, metal, and insulated panels, including trim, access doors, and ventilation. Keep the existing skirting if it is sound and only a limited area needs repair, but do not cover damaged supports with new panels.
Clear vegetation and movable items from around the home before the crew arrives, if safe and permitted. This can reduce labor time, but homeowners should not enter unsafe crawl spaces or move utility connections. Coordinate park approval and permit questions early to avoid schedule delays or rework.
Collect at least three itemized estimates that use the same measurements and scope. Compare material specifications, labor, removal, disposal, access panels, vents, warranty terms, and exclusions—not just the bottom-line price. A good quote explains how unforeseen soil, leveling, or utility conditions affect the charge and requires approval before additional work proceeds.
