Mobile Home Skirting: Types, Costs and How to Choose

Most skirting problems start with a material picked for looks alone. Mobile home skirting closes the gap between the bottom of the home and the ground, and it does real work: it keeps animals out, cuts wind under the floor, protects plumbing from freezing and gives the home a finished look. Choose a panel that cannot breathe, buckles when the ground freezes or blocks a furnace vent, and you trade a cosmetic fix for moisture, rot and safety trouble.

The short answer: vinyl is the budget and DIY favorite, metal is tougher and cheaper over long runs, faux rock and brick panels look the most like a site-built foundation, concrete block is the most permanent, and wood is easy to customize but needs the most care. Whatever you pick, plan for cross-ventilation openings, at least one access panel, and a small gap at the ground so frost heave does not tear the panels off the home.

Mobile Home Skirting Materials Compared

Five material families cover nearly every home, from a single wide in a park to a double wide on private land. Each one balances price, lifespan and how much labor you want to put in.

A typical single wide has about 150 to 180 linear feet of perimeter, and a double wide runs 180 to 220 feet, so the material choice can swing the total by several thousand dollars. Prices vary by region and by how uneven your ground is.

Vinyl skirting

Vinyl is the most common choice for manufactured home skirting because it is light, inexpensive and fits into top and bottom tracks that a homeowner can install in a weekend. Panels come vented and solid, in many colors, and they cut with tin snips or a fine-tooth saw. The downside is impact strength. Vinyl gets brittle in hard cold, cracks when a mower throws a rock, and can be pushed in by a determined dog. If you go this route, vinyl skirting panels with a rib pattern and a thicker gauge hold up noticeably better than the thinnest economy stock.

Metal skirting

Metal skirting panels, usually galvanized or painted steel, sometimes aluminum, shrug off pets, rodents and wind far better than vinyl. Corrugated metal skirting suits rustic and farm settings, while flat painted panels pass for a cleaner look. Metal trailer underpinning conducts cold, so it does little for insulation on its own, and cut edges must be sealed or they will rust near the soil. Wear gloves: fresh-cut steel edges slice skin easily.

Faux rock and brick panels

Molded polyurethane or polypropylene panels imitate fieldstone, ledgestone or brick. They are the closest you get to the look of a permanent foundation without pouring one, which can help with appraisal and neighborhood fit. They cost more, need careful joint alignment so the pattern does not look repetitive, and still need vent panels worked in at the right spacing.

Concrete block

Block skirting sits on a small footing below the frost line in cold regions and is mortared or dry-stacked with surface bonding. It is fireproof, pest-proof and lasts for decades. It is also heavy, slow and the hardest to undo if the home ever moves. Plan proper vent blocks and an access opening from the start, because cutting them in later is a chore.

Wood skirting

Pressure-treated lumber, board-and-batten or lattice can match a porch or deck and is easy to cut around steps. Wood rots where it touches soil, so keep it on a treated bottom rail with a gap above grade, and expect to stain or paint every few years. Lattice alone does little against wind or animals unless it is backed with hardware cloth.

Ventilation Openings: The Part You Cannot Skip

The crawlspace under a manufactured home needs air movement. Without it, moisture from the soil condenses on the belly wrap, ductwork and floor framing, and you end up with sagging subfloors, mold and musty smells inside. Many installation manuals call for net free vent area of roughly 1 square foot for every 150 square feet of floor area, with vents placed on opposite sides for cross-ventilation and within a few feet of each corner. If a ground vapor barrier is installed, some manuals allow less. Your home’s installation manual and your local authority have the final say, so read both before you buy panels.

In practical terms, that means mixing vented panels into every run rather than skirting the whole home solid. Count the net free area listed on the vent, not the overall panel size; louvers and screens block a good share of the opening. Keep vents clear of shrubs, mulch piles and snow drifts.

Keep Appliance Vents Outside the Skirting

This is the safety rule that gets missed most often. Dryer exhaust, furnace flues and combustion air, and water heater vents must discharge to open air outside the skirting, never into the enclosed crawlspace. A dryer venting under the home pumps lint and moisture into the space, which is both a fire risk and a mold source. A fuel-burning furnace or water heater that exhausts or draws air from a closed crawlspace can backdraft and create a carbon monoxide hazard.

• Extend the dryer duct through the skirting with a rigid or semi-rigid metal duct and an exterior hood with a damper.
• Leave furnace and water heater flue terminations and combustion air openings exactly as the manufacturer and your installer specified; do not box them in.
• If an existing gas appliance vent is in the way, call a licensed HVAC or gas technician rather than rerouting it yourself.
• Keep working smoke and carbon monoxide alarms inside the home.

Access Panels and Frost Heave Gaps

You will need to get under the home for plumbing leaks, heat tape, duct repairs and inspections. Build at least one removable access panel, typically about 18 by 24 inches or larger, near the main water shutoff and plumbing drop. Many owners add a second one on the opposite end. Hinged or lift-out panels with simple latches beat panels you have to unscrew in the rain.

Frost heave is the other big failure. In cold climates the ground can rise an inch or more in winter. If skirting is fastened tight at the top and buried at the bottom, the rising soil buckles panels or rips the top track off the home. Use a floating bottom track or leave a small gap, often about 1 inch, between the panel bottom and a ground track so the soil can move without lifting the skirting. In areas with deep frost, block skirting needs a footing below the frost line for the same reason.

How to Install Vinyl or Metal Skirting

Here is the general sequence for track-based panel systems, which covers most vinyl and many metal kits.

1. Measure and order. Measure the full perimeter and the height at several points along each side. Ground is rarely level, so note the tallest and shortest spots. Add 10 percent for waste, plus vented panels, corner trim and access panels.
2. Clear the line. Remove debris, rake a flat strip about 12 inches wide and grade soil so water drains away from the home.
3. Set the ground track. Lay the bottom track on firm soil or a gravel bed, staked every 2 to 3 feet. Keep it level within each run, stepping down only where the grade changes.
4. Attach the top track. Fasten it to the rim of the home with screws at the spacing the kit calls for. Do not drive fasteners into the belly wrap or wiring.
5. Cut and fit panels. Cut each panel to height minus the frost gap, slide it into the top track, then drop it into the ground track. Interlock seams as you go.
6. Place vents and access. Install vented panels at the spacing your ventilation math requires, frame the access panel, and cut neat openings for the dryer duct, flues and hose bibs.
7. Finish corners. Cap corners and ends with trim and check that every panel sits in both tracks.

Most DIY crews finish a single wide in one or two days and a double wide skirting job in two to three. Faux rock usually follows the same track logic with extra time spent aligning the pattern.

Insulation, Pests and Moisture

Skirting is not insulation, but it helps. Rigid foam board inside vinyl or metal panels can reduce drafts and protect pipes in very cold regions, as long as vent openings stay open and the foam is rated for ground contact. Heat tape on supply lines and an intact belly wrap do more for frozen pipes than skirting alone.

For pests, bury a strip of hardware cloth 6 to 12 inches into the soil just inside the skirting, bent outward in an L shape. That stops most digging animals without blocking airflow. A 6-mil polyethylene ground cover under the home cuts soil moisture dramatically and is one of the cheapest upgrades you can make.

Troubleshooting Common Skirting Problems

• Panels bowing out each spring: frost heave. Add or widen the gap at the bottom track and improve drainage.
• Condensation or musty odor under the home: not enough vent area, a dryer venting under the home, or no ground vapor barrier.
• Panels blowing loose: top track fasteners too far apart or driven into thin trim instead of the rim.
• Cracked vinyl: impact in cold weather; replace single panels and consider metal on the windward or high-traffic side.
• Animals still getting in: gaps at corners, steps or around utility drops; seal with trim and buried hardware cloth.

How to Choose and When to Hire a Pro

The right mobile home skirting depends first on your climate and site. Cold winters favor block on a footing or panels with a well-designed frost gap. Windy or rural lots favor metal. Parks often set rules on color and material, so check community guidelines before ordering. Tiny homes and park models follow the same rules at a smaller scale, and modular home skirting may need to match a permanent foundation look for financing.

Hire a contractor when the ground has steep slopes, when you want block or a poured footing, or when utilities, flues or gas lines sit in the skirting line. Labor typically adds $3 to $10 per linear foot for panel systems and more for masonry. A pro also helps if the home is being set up new, since tie-downs and piers should be inspected before the base is closed in.
