Greenhouse plastic sheeting typically costs $0.08-$0.30 per square foot for standard UV-treated film, with specialty coverings priced higher. A full replacement can run from a few hundred dollars for a small DIY greenhouse to several thousand for a large structure; film thickness, greenhouse dimensions, labor, and removal are the main cost drivers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 6-mil greenhouse film | $0.08 per sq ft | $0.15 per sq ft | $0.30 per sq ft | UV-treated film; price varies by roll size and brand |
| Small DIY re-cover | $75 | $250 | $600 | About 500-1,000 sq ft of film, before major repairs |
| Installed re-cover | $600 | $1,800 | $5,000+ | Size, access, labor, and disposal change the quote |
| Specialty film | $0.20 per sq ft | $0.35 per sq ft | $0.70+ per sq ft | May include anti-drip, infrared, or multi-layer features |
What greenhouse plastic costs by roll size
Standard greenhouse polyethylene film is commonly sold in 4-, 6-, and 8-mil thicknesses. For a home greenhouse, 6-mil UV-stabilized film is a frequent choice; it offers a practical balance of strength and price. Typical material pricing is about $0.08-$0.30 per square foot, with small retail packages often costing more per square foot than large rolls.
A 10-by-25-foot sheet covers 250 square feet and may cost about $25-$75. A 20-by-50-foot roll covers 1,000 square feet and often runs $80-$250. Larger 24-by-100-foot rolls may cost $200-$600, depending on thickness, treatment, and supplier. These are material prices, not installed prices.
For standard 6-mil UV-treated film, budgeting $0.10-$0.25 per square foot is a reasonable starting point. Measure the structure’s full covering area, including roof curves, end walls, overlaps, and material needed to secure the edges. A greenhouse’s floor area alone is not enough to determine the required sheet size.
Assumptions: U.S. retail pricing, standard clear polyethylene film, and no delivery charge.
What roof film, labor, and hardware add to a quote
A re-covering quote may include more than the plastic itself. Installers can charge separately for removing old film, fitting new sheets, replacing worn fastening parts, and hauling away debris. The table below shows common cost components for a small-to-mid-size greenhouse project.
| Cost component | Typical price | Pricing basis | When it applies |
|---|---|---|---|
| 6-mil UV film | $0.08-$0.30 | Per sq ft | Standard clear cover |
| Installation labor | $50-$100 | Per worker-hour | Cutting, stretching, and fastening film |
| Lock channel and wiggle wire | $1-$4 | Per linear ft | New or replacement fastening hardware |
| Old-film removal and disposal | $100-$500 | Per job | Depends on size and disposal access |
| Repair of frame or end wall | $100-$1,000+ | Per job | Only if damaged parts need work |
Hardware costs rise when existing channels are corroded, loose, or incompatible with the new film. On a structure with sound channels, reusing them can avoid a substantial materials charge. If the quote includes new framing, doors, or vents, ask for those items to be priced separately from the plastic replacement.
Fastening hardware and preparation can add $100-$800 or more, even when the film itself costs only a few hundred dollars. For example, 12-20 labor hours at $50-$100 per hour equals $600-$2,000 in labor.
How greenhouse size and film specs change the price
Covering area is the first major variable. A 10-by-12-foot hobby greenhouse may need roughly 350-500 square feet of film after allowing for walls, roof shape, and overlap. A 20-by-48-foot hoop house can require about 2,500-3,200 square feet, depending on its height and end-wall design. The difference in area can multiply material costs several times over.
Film thickness and treatment also affect the estimate. Standard 4-mil film may cost less, but it is more vulnerable to tearing than 6-mil film and may be intended for shorter-term or protected applications. Eight-mil film and reinforced products can cost more per square foot but may suit exposed locations or structures where added durability matters. UV stabilization is important for outdoor greenhouse use; ordinary construction plastic may degrade faster in sunlight.
Specialty features change the price further. Anti-drip film can help reduce water droplets on plants, while infrared or thermal additives may help retain heat. These products can run approximately $0.20-$0.70+ per square foot. Compare the stated product life and warranty as well as the price, since a cheaper film that needs more frequent replacement may cost more over time.
For a 2,500-square-foot cover, each extra $0.10 per square foot adds $250 to the film bill. Sloped or curved roofs, large end walls, double-layer systems, and extra overlap all increase the amount required.
How much installer labor does a re-cover need
A simple small greenhouse can take one or two people several hours to cover, while a larger hoop house may require a crew and a full workday or more. Typical labor rates are about $50-$100 per worker-hour, though regional contractor rates and minimum job charges vary. Some installers price the work as a fixed project rather than listing hourly labor.
Wind, uneven ground, tall sidewalls, and difficult access can slow installation. Film is easier to handle when the weather is calm; gusts can make a large sheet hard to stretch evenly and may increase the risk of damage. A crew may also need extra time to remove old coverings, repair fastening channels, or work around vents and irrigation equipment.
For a straightforward 1,000-2,000-square-foot re-cover, labor may be about $400-$1,600; complicated access or repairs can push it higher. Ask whether the quote includes crew size, estimated hours, removal, hardware, and cleanup. A low labor figure may not include those tasks.
Regional greenhouse plastic prices and delivery
Material prices can be relatively similar nationwide when buyers order the same film online, but shipping and local availability create differences. In remote areas, bulky rolls may incur freight charges or require pickup from an agricultural supplier. Local store pricing can also be higher for small packages than wholesale or farm-supply pricing for full rolls.
Installed quotes often vary more than material prices. As a broad comparison, urban markets with higher labor rates may run 10%-25% above typical national labor estimates. Rural regions may have lower hourly rates but fewer contractors, longer travel distances, or a minimum service charge that raises the final total. These are planning ranges, not guaranteed regional price adjustments.
Compare delivered price per square foot, not just the listed roll price. Freight, sales tax, and the usable dimensions after overlaps can change which roll is the better value. For installed work, request quotes from contractors familiar with greenhouse film rather than assuming a general roof-covering rate applies.
When a patch costs less than replacing greenhouse film
A small tear in otherwise flexible, UV-stable film may be repairable with greenhouse repair tape. A roll of suitable tape commonly costs about $10-$35, while a small patch kit may cost $15-$50. A contractor’s minimum visit charge can make professional repair cost $100-$300 or more, even if the damaged area is small.
Replacement becomes more practical when the covering has widespread brittleness, multiple tears, loose edges, or poor light transmission. If film is only a few years old and damage is localized, a patch may extend its service life. If it has become cloudy or cracks when handled, repeated repairs may be less economical than installing new film.
Film life varies with UV treatment, weather exposure, tension, and installation. Many greenhouse films are marketed for roughly three to five years, while some premium products claim longer service under specified conditions. Check the manufacturer’s warranty terms and whether they require particular installation methods.
Patch localized damage for roughly $10-$50 in materials; replace film when deterioration is widespread or repairs keep recurring. A repair quote should identify whether the frame, fastening channel, or only the covering caused the problem.
Extra charges for disposal, delivery, and double-layer systems
Old film removal can add roughly $100-$500 for a typical project, with larger or tangled coverings costing more to handle. Disposal may be included in the removal charge or billed separately. Confirm whether the contractor will take away the old plastic, since some local waste facilities have restrictions on agricultural film.
Delivery can range from free local pickup to $50-$250 or more for bulky rolls shipped to a residence. A lift, ladder, or additional crew may be necessary on tall structures. Small projects may also face a contractor minimum of about $150-$400, particularly when travel time is significant.
Double-layer inflatable covers require two sheets, a blower, and compatible installation details. The second layer can nearly double film needs, and blower equipment may add about $100-$400, depending on capacity and features. Replacing a blower or adapting an older greenhouse can add parts and labor beyond the film price.
Request a written line-item quote that separates film, freight, removal, fastening hardware, and any blower or frame work. This makes it easier to compare estimates that appear different because one includes disposal or equipment and another does not.
Ways to reduce greenhouse film costs without underbuying
Measure the roof and end walls carefully before ordering. Include enough material for overlap and fastening, but avoid ordering an oversized roll without checking whether the supplier offers a better-fit width. A greenhouse film calculator can help with initial estimates, but the structure’s actual dimensions should govern the order.
Choose film based on the greenhouse’s exposure and intended use rather than automatically buying the thickest option. For a protected hobby structure, standard UV-treated 6-mil film may be sufficient; exposed sites or high-use operations may justify a stronger or specialty product. Compare price per square foot and warranty terms, not only the total roll price.
Reuse sound lock channels and schedule the job before the covering fails completely. A planned replacement allows time to compare suppliers and arrange calm-weather installation, while an emergency repair can involve extra labor or delivery charges. Combining film work with already-planned greenhouse maintenance may reduce repeat travel or setup charges.
The largest controllable savings usually come from accurate measurement, sound hardware reuse, and avoiding unnecessary premium features. Get at least two itemized quotes using the same film thickness, treatment, coverage area, and removal scope so the comparison reflects the actual price difference.
