How Much Is It to Side a House?
Replacing the exterior siding on your home is one of the most transformative home improvement investments you can make, instantly rejuvenating curb appeal, elevating energy efficiency, and protecting structural framing from weather damage. On average, the cost to side a house ranges between $6,000 and $22,000 for a typical 1,500 to 2,500 square-foot single-family home, with overall costs averaging $5 to $14 per square foot of exterior wall surface installed. Material selection—spanning economical vinyl, durable fiber cement, classic cedar wood, or modern metal—is the single largest factor dictating your final invoice.
Siding Material Classes, Durability, and Cost Per Square Foot
In the exterior cladding industry, pricing is universally calculated by the siding square, where one square equals exactly 100 square feet of finished wall surface area. Vinyl siding remains the most popular and budget-friendly option across North America, costing $400 to $800 per square installed ($4 to $8 per square foot). Vinyl is lightweight, immune to insect rot, never requires painting, and is available in standard hollow-back profiles or insulated foam-backed panels that boost thermal R-value performance.
For homeowners seeking increased durability, architectural depth, and fire resistance, fiber cement siding (dominated by James Hardie HardiePlank) has become the gold standard, costing $800 to $1,500 per square installed ($8 to $15 per square foot). Composed of Portland cement, sand, and cellulose wood fibers, fiber cement is non-combustible, impervious to woodpeckers and termites, and carries a 30 to 50-year lifespan. Natural wood siding (such as Western red cedar lap or shingles) costs $900 to $1,800 per square, requiring regular staining, while engineered wood (LP SmartSide) delivers wood warmth with synthetic resins for $600 to $1,100 per square.
Compare leading siding materials, expected lifespans, fire resistance ratings, and installed costs per square:
| Siding Material Type | Material Composition | Lifespan Expectancy | Installed Cost Per Square (100 Sq Ft) | Installed Cost Per Sq Ft |
|---|---|---|---|---|
| Standard Hollow Vinyl Siding | Extruded polyvinyl chloride (PVC) | 20 to 30 Years | $400 to $750 | $4.00 to $7.50 |
| Insulated Foam-Backed Vinyl | PVC bonded to contoured EPS foam | 25 to 35 Years | $600 to $950 | $6.00 to $9.50 |
| Engineered Wood (LP SmartSide) | Wood strands, wax, resin binders | 30 to 50 Years | $650 to $1,100 | $6.50 to $11.00 |
| Fiber Cement (James Hardie) | Portland cement, silica sand, cellulose | 40 to 50+ Years | $850 to $1,500 | $8.50 to $15.00 |
| Natural Cedar Lap Siding | Western red cedar lumber | 25 to 40 Years (With care) | $950 to $1,800 | $9.50 to $18.00 |
| Modern Standing-Seam Steel | 26-gauge galvanized architectural steel | 50+ Years | $1,100 to $2,200 | $11.00 to $22.00 |
Tear-Off Labor, Weather Barriers, and Sheathing Repairs
A significant portion of your siding contractor estimate encompasses demolition labor, waste disposal, and wall preparation beneath the visible panels. Removing and disposing of old existing siding typically costs $1,000 to $3,500 ($1.00 to $2.50 per square foot), depending on whether your home has a single layer of old vinyl or brittle, heavy asbestos-cement or lead-painted wood shingles requiring hazardous disposal containment.
Once old siding is stripped, contractors must inspect the underlying oriented strand board (OSB) or plywood wall sheathing. Replacing rot-damaged sheathing sheets adds $75 to $120 per 4x8-foot sheet. Installing a modern weather-resistive vapor barrier (such as DuPont Tyvek home wrap) along with flashing tapes around window frames ($0.50 to $1.20 per square foot) is vital to stop wind-driven rain infiltration while allowing interior wall moisture vapor to escape harmlessly.
Review typical line-item labor tasks, trim accessories, and auxiliary expenses in a full siding replacement:
| Labor & Accessory Component | Scope of Construction Work | Typical Cost Range | Percentage of Project | Cost-Saving Tip |
|---|---|---|---|---|
| Tear-Off & Dumpster Hauling | Stripping old siding, dumpster rental, disposal | $1,200 to $3,200 | 10% to 15% | Ensure dumpster fees are included in quote |
| Plywood Sheathing Repair | Replacing rotted OSB/plywood sections | $80 to $130 per sheet | 2% to 6% | Maintain clean gutters to prevent wall rot |
| House Wrap & Window Flashing | Tyvek vapor barrier and self-adhering tape | $600 to $1,500 | 5% to 8% | Never skip a high-quality breathable house wrap |
| Soffit & Fascia Replacement | Aluminum or vinyl eaves and overhang trim | $1,500 to $4,000 | 12% to 18% | Bundle soffit replacement with siding for discounts |
| Corner Posts & Window Trim | J-channels, outside corner posts, window casing | $1,000 to $2,500 | 8% to 12% | Choose contrasting trim colors for curb appeal |
Energy Efficiency Improvements, ROI, and Contractor Selection
Re-siding your house offers an ideal opportunity to upgrade exterior thermal envelope performance. Contractors can install a continuous layer of rigid extruded polystyrene (XPS) or polyisocyanurate foam insulation board beneath your new siding ($0.60 to $1.50 per square foot). This continuous thermal barrier breaks thermal bridging across wood wall studs, reducing heating and cooling utility costs by 8 to 15 percent and keeping rooms noticeably quieter and more comfortable year-round.
From a financial return standpoint, siding replacement consistently ranks among the highest return-on-investment exterior remodeling projects in the annual Remodeling Cost vs. Value Report. Vinyl siding replacements routinely recoup 65 to 75 percent of their cost at home resale, while fiber cement siding recoups 70 to 82 percent. Always collect three detailed bids from factory-certified siding installers (such as James Hardie Elite Preferred contractors) carrying active licensing and comprehensive workers compensation insurance.
How to Plan and Execute a House Siding Project in 5 Steps
Follow these five strategic milestones to calculate wall area, select cladding materials, and manage your siding installation.
Calculate Exterior Wall Square Footage
Measure perimeter wall lengths and heights, subtract large window and door openings, and divide by 100 to estimate siding squares needed.
Select Siding Material and Architectural Profile
Choose between affordable vinyl, resilient fiber cement, or modern steel based on your neighborhood home values and maintenance goals.
Collect Multiple Itemized Contractor Quotes
Solicit bids from at least three licensed siding specialists, verifying that estimates itemize tear-off, sheathing repair, house wrap, and soffits.
Inspect Underlying Sheathing and Weather Barrier
Conduct a visual walkthrough with the project manager after old siding is removed to identify any hidden dry rot or termite damage.
Perform Final Punch List and Magnet Sweep
Examine caulking around windows and corner seams, test exterior lights, and ensure the crew runs a rolling magnetic sweep for stray nails.
