Bison deck supports typically cost about $8-$30 per pedestal, with many standard residential projects averaging $15-$20 per support. Total pricing depends on pedestal height and accessories, how many supports the deck needs, surface preparation, and whether installation labor is included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Adjustable support | $8 each | $17 each | $30 each | Height and model affect price |
| Supports per square foot | $8 | $17 | $30 | About one per sq ft for many 24-by-24-inch layouts |
| Supports for 200 sq ft | $1,600 | $3,400 | $6,000 | Supports only; before accessories and labor |
| Installed support system | $12 per sq ft | $25 per sq ft | $45 per sq ft | Labor and basic setup; decking surface may be extra |
What Bison deck supports cost for a typical rooftop deck
For supports alone, a practical budgeting range is $8-$30 each, or approximately $8-$30 per square foot when the layout uses one support per square foot. A 200-square-foot area could therefore need about 200 supports and cost roughly $1,600-$6,000 for pedestals. Many standard-height residential installations land near $3,400 for that quantity.
These estimates cover the adjustable supports, not the pavers, wood tiles, waterproofing, or structural repairs. The assumed layout uses 24-by-24-inch surface units, typical support spacing, standard materials, and normal access. Higher pedestals, slope adjustment, unusual edges, and local freight can raise the quote. Assumptions: U.S. retail pricing, standard residential project, no structural or membrane repairs.
How pedestal height and accessories shape the quote
Quotes can combine the supports with slope-correction parts, spacing tabs, shims, perimeter restraints, or other components needed for the selected deck surface. Ask the supplier to list the model and quantity for each line item; a low pedestal price may not include the parts required to level the full area.
| Quote item | Typical price | Pricing basis | What changes it |
|---|---|---|---|
| Standard adjustable pedestal | $8-$20 | Per support | Height range and load rating |
| Tall or specialized pedestal | $18-$30 | Per support | Greater height or specialized configuration |
| Slope-adjustment component | $3-$12 | Per support position | Roof pitch and leveling needs |
| Installation labor | $4-$15 | Per sq ft | Layout complexity and access |
| Freight and handling | $100-$600 | Per delivery | Order size and delivery distance |
Confirm whether the quote prices supports by piece or by square foot and whether freight is included. Accessory charges vary by layout, so the table is a planning range rather than a fixed Bison price list.
Why 24-inch pavers and pedestal height change support counts
For 24-by-24-inch pavers, a common starting estimate is one support per square foot, or about 100 supports for 100 square feet. Actual placement depends on the paver layout, edge conditions, manufacturer instructions, and whether supports are shared at adjoining corners. Smaller units and cut edges may need additional support positions.
Height is another major cost driver. Standard-height supports may fall near $8-$20 each, while taller or specialized units can reach $18-$30 each. A roof slope around 1/4 inch per foot or greater may require more leveling work or slope-adjustment components. Have the supplier or installer verify support spacing and height against the exact surface and site conditions.
What labor adds to a Bison pedestal installation
Installation labor often runs about $4-$15 per square foot for straightforward placement and adjustment, with higher rates for restricted rooftop access, many cuts, or difficult leveling. At $75-$125 per hour, a two-person crew working 10-20 hours would represent about $1,500-$5,000 in labor.
Labor usually covers layout, support placement, height adjustment, and basic cleanup, but not deck-surface installation in every quote. Ask whether the price includes moving materials to the work area and whether the installer charges a minimum for small jobs. Removing an existing deck surface or correcting a substrate can be billed separately.
Three project examples for different deck sizes
A 100-square-foot balcony with standard-height supports might use about 100 units at $12-$18 each, or $1,200-$1,800 for supports. Add $400-$1,200 for simple labor and the support portion totals about $1,600-$3,000, excluding the walking surface.
A 200-square-foot rooftop with standard pavers could require about 200 supports at an average $17 each, or $3,400. If labor is $6-$12 per square foot, another $1,200-$2,400 brings the support-and-installation subtotal to about $4,600-$5,800, before delivery and pavers.
A 300-square-foot roof with taller supports and slope correction may use 300 units at $20-$30 each, or $6,000-$9,000. Labor at $10-$15 per square foot adds $3,000-$4,500, putting the subtotal around $9,000-$13,500. These examples exclude pavers, waterproofing, permits, and structural work.
When regional freight and rooftop access raise the price
Prices vary with shipping distance, supplier availability, and local labor. In major coastal metros and other high-cost markets, labor and delivery can be roughly 10%-25% above a typical national estimate; rural locations may face a similar premium when delivery routes or installer availability are limited. Material prices may differ less than labor and freight.
Rooftop access can add handling charges when supports must be carried through a building, lifted by crane, or delivered in multiple loads. Request a delivered price for the full quantity and confirm whether unloading is included. Freight and access fees can materially change a small order’s per-support cost.
How to lower the support budget without weakening the layout
Provide accurate dimensions, roof height, slope, surface type, and access details before requesting bids. Compare quotes using the same pedestal model, quantity, accessory list, freight terms, and labor scope. A price per square foot is useful only when the support spacing and included work match.
Choose the lowest suitable height range rather than paying for excess adjustment capacity, and avoid ordering before the installer confirms edge and cut-piece requirements. Combining the support order with other project materials may reduce delivery charges. Do not reduce support counts below the approved layout to save money. Cost control should come from accurate quantities and clear scope, not unsupported spacing changes.
Repairing a few supports versus replacing the deck system
If only a small area is uneven, a targeted adjustment or replacement of individual supports may cost less than rebuilding the entire field. A small service visit can run about $150-$500, depending on minimum labor charges, access, and whether replacement parts are needed. Replacing supports across a large area can approach the original support cost, especially if the surface must be lifted and reset.
Before approving repairs, determine whether the movement comes from the supports, the underlying roof or patio, or water-related damage. Supports do not correct a failing substrate or waterproofing problem. Get the cause identified before comparing a repair quote with full replacement pricing.
