Composite siding cost: 2026 Installed Price Calculator
Mike Martin, MA CSL, is the founder and construction cost editor of RemodelingExpense. His residential construction experience informs the site’s cost research, calculators, and homeowner project guidance.
Composite siding cost runs about $10 – $18 per square foot installed, so a typical 1,500 square foot project lands around $15,000 – $27,000. The final price depends on board type, trim system, fastener rules, expansion gaps, factory finish, moisture clearances, and local labor rates.
Composite siding is a broad category that can include polymer composite, cellular PVC, mineral-based siding, resin-based boards, and other manufactured siding systems. It usually costs more than basic vinyl because the product, trim, fastening, and installation details are more specific.

Not sure what square footage to enter? Use the outside wall area being covered, not indoor living space. If you are replacing one elevation or adding composite siding to an accent area, measure just that section.

Why your price may change
- Local labor rates vary.
- Material quality affects the price.
- Old material removal, repairs, permits, or code updates can add cost.
- Hard-to-reach areas, complex layouts, rush jobs, or premium contractors may cost more.
Estimate includes local labor adjustments and may differ slightly from rounded national cost examples.
Composite Siding Cost vs Value
Composite Siding may recover about 55%–74% of its cost.
Bottom line: Composite siding can improve curb appeal and reduce exterior maintenance, but the value depends on the product type, finish, warranty, trim system, and whether the home benefits from a premium manufactured siding.
Worth it: Homes where a durable manufactured siding with a clean finish, low upkeep, and stronger trim package makes sense.
Skip it: Homes where basic vinyl, aluminum, or standard engineered wood siding meets the budget and design goal for less.
ROI ranges are planning estimates and should not be treated as an appraisal. This is only an estimate. Real resale value depends on your home, neighborhood, market, project quality, and buyer demand.
Contractor Reality Check
Composite siding quotes can vary because “composite” does not mean one single material. A cellular PVC product, polymer composite panel, and mineral-composite board may all price differently.
My rule of thumb: compare the exact product line, trim system, finish, and warranty before comparing the square-foot price.
What to Confirm Before You Sign
A good quote is easy to read. If any of these are missing or vague, ask before you commit:
- Product type: confirm whether the siding is polymer composite, cellular PVC, mineral composite, or another manufactured board.
- Trim system: ask if matching corners, window trim, fascia, soffit, and transition boards are included.
- Fasteners: confirm the approved fasteners, spacing, and whether hidden fasteners are required.
- Expansion gaps: ask how the crew handles movement, butt joints, ends, and long wall runs.
- Moisture details: confirm flashing, clearances, drainage, and wall preparation before install.
- Finish: ask if the product is factory finished, field painted, or needs special touch-up work.
- Buffer: budget an extra 7% to 15% for surprises, access issues, or upgrades.
Surprise Costs That Move the Price
These are the items that push a composite siding quote above the basic price range, and roughly what they add.
| Item | Why It Adds Cost | Typical Add |
|---|---|---|
| Old siding removal | Tear-off adds labor, disposal, and repair risk | $1 – $2 per sq. ft. |
| Rotten sheathing | Soft plywood or OSB must be replaced before new siding goes on | $125 – $250 per 4×8 sheet |
| Premium trim package | Matching corners, window trim, and transition boards add material and labor | $1,000 – $4,000+ |
| Factory finish | Prefinished boards or panels usually cost more than unfinished material | $1 – $3 per sq. ft. |
| Complex wall layout | Gables, bump-outs, porches, and many openings slow the install | Varies by layout |
| Installer familiarity | Specialty composite systems may need a crew that knows the product rules | Varies by market |
Composite Siding Cost by Type
| Type | Installed Cost per sq. ft. | Best For |
|---|---|---|
| Basic composite lap siding | $10 – $15 | Full-home manufactured siding replacement |
| Cellular PVC siding | $12 – $18 | Moisture-prone areas and premium trim systems |
| Polymer composite panels | $11 – $18 | Low-upkeep exterior upgrades |
| Composite board and batten | $12 – $18 | Vertical accent walls and farmhouse-style designs |
| Composite accent areas | $12 – $20 | Gables, dormers, porches, and front elevations |
Composite Siding Cost by Project Size
The larger the project, the more boards, trim, fasteners, flashing, removal, cleanup, and labor the job needs. These examples use estimated siding square footage, not indoor living space.
| Project Size | Estimated Installed Cost |
|---|---|
| 1,000 sq. ft. | $10,000 – $18,000 |
| 1,500 sq. ft. | $15,000 – $27,000 |
| 2,000 sq. ft. | $20,000 – $36,000 |
| 2,500 sq. ft. | $25,000 – $45,000 |
| 3,000 sq. ft. | $30,000 – $54,000 |
| 3,500 sq. ft. | $35,000 – $63,000 |
Is Composite Siding Worth It?
Composite siding is worth it when you want a premium manufactured exterior with strong curb appeal, low upkeep, and a clean trim package.
It may not be worth it if the project only needs a basic siding replacement. Vinyl, aluminum, or standard engineered wood may meet the budget and design goal for less.
