How Much Does New Siding on a House Cost?
Installing new siding on a house typically costs between $6,000 and $18,000 for standard vinyl siding on an average 1,500 to 2,500-square-foot home, while upgrading to premium fiber cement (such as James Hardie board), engineered wood, or composite siding averages $12,000 to $28,000. New exterior cladding revitalizes home curb appeal, provides crucial weatherproofing against storm moisture, and boosts residential thermal efficiency when paired with rigid foam continuous insulation. Total project investments depend on exterior wall square footage, architectural complexity (dormers and multiple stories), chosen cladding material, existing siding tear-off demolition, and rot repairs to underlying sheathing.
Installed Siding Costs per Square Foot by Material
Residential siding materials span a broad spectrum of cost, aesthetics, and structural durability. Standard hollow vinyl siding remains America's most popular exterior cladding due to its low cost of $4.50 to $8.50 per square foot installed. Insulated vinyl siding ($7.00 to $12.00 per sq ft) incorporates bonded rigid expanded polystyrene (EPS) backing that increases wall R-value and delivers improved impact resistance against hail.
Fiber cement siding (James Hardie) has become the gold standard for durability, costing $8.00 to $15.00 per square foot installed. Composed of sand, cellulose fibers, and Portland cement, fiber cement is non-combustible with a Class A fire rating, impervious to wood-boring insects, and mimics authentic cedar lap siding. Natural wood cedar siding ($10.00 to $18.00 per sq ft) and engineered wood (LP SmartSide, $7.50 to $13.50 per sq ft) offer warm organic beauty with rot-resistant wax-treated wood strands.
The comparison table below details average material and installation costs per square foot and total project estimates for a typical 2,000 sq ft home exterior.
| Siding Material Type | Installed Cost per Sq Ft | Average Total Cost (2,000 Sq Ft) | Expected Lifespan | Maintenance Requirements |
|---|---|---|---|---|
| Standard Vinyl Lap Siding | $4.50 to $8.50 | $9,000 to $17,000 | 20 to 30 Years | Annual pressure wash; crack repairs |
| Insulated Vinyl Siding | $7.00 to $12.00 | $14,000 to $24,000 | 25 to 35 Years | Low maintenance; enhanced energy efficiency |
| Fiber Cement (James Hardie) | $8.00 to $15.00 | $16,000 to $30,000 | 40 to 50+ Years | Repainting every 12 to 15 years |
| Engineered Wood (LP SmartSide) | $7.50 to $13.50 | $15,000 to $27,000 | 30 to 40 Years | Repainting every 8 to 12 years |
| Natural Cedar Bevel Siding | $10.00 to $18.00 | $20,000 to $36,000 | 25 to 40 Years | Staining or painting every 3 to 5 years |
| Manufactured Stone Veneer Accent | $16.00 to $30.00 | $32,000 to $60,000 | 50+ Years | Periodic mortar inspection and wash |
Siding contractors measure wall surfaces in 'squares', where one construction square equals exactly 100 square feet of finished wall area.
Old Siding Tear-Off, Sheathing Repairs, and House Wrap
When replacing siding, homeowners must account for preliminary demolition and structural preparation work. Stripping off existing damaged vinyl, cedar shake, or aluminum siding costs $1.00 to $2.50 per square foot, which includes carting debris to local landfills. If previous siding leaks allowed rain intrusion, replacing rotted 7/16-inch OSB or plywood wall sheathing costs $75 to $130 per 4x8-foot sheet.
Installing a high-performance weather-resistant barrier (WRB) such as DuPont Tyvek HomeWrap or Henry Blueskin weatherproofing membrane ($0.40 to $1.10 per sq ft) is vital before new siding is hung. House wrap acts as a drainage plane, shedding wind-driven rain while allowing trapped indoor water vapor to escape outward. Installing pre-bent aluminum trim coil over window casing, door trim, and fascia boards ($1,500 to $3,500) creates a cohesive, maintenance-free exterior package.
The breakdown below outlines common preparatory, demolition, and weatherproofing expenses encountered during siding replacement.
| Prep / Accessory Service | Cost Range per Unit | Measurement Basis | Role in Wall Envelope Performance |
|---|---|---|---|
| Old Siding Tear-Off & Disposal | $1.00 to $2.50 / Sq Ft | Wall surface area | Removes degraded siding down to wood sheathing |
| Rotted Wood Sheathing Replacement | $75 to $130 / Sheet | 4x8 Ft OSB/Plywood | Restores structural nail base for fasteners |
| Vapor-Permeable House Wrap (Tyvek) | $0.40 to $1.10 / Sq Ft | Wall surface area | Water-resistant drainage barrier under siding |
| Rigid Foam Continuous Insulation (1") | $1.20 to $2.20 / Sq Ft | Wall surface area | Thermal break preventing thermal bridging through studs |
| Aluminum Window & Trim Coil Capping | $15 to $35 / Linear Ft | Perimeter window trim | Protects exterior wood trim from rot; zero painting needed |
Replacing old drafty siding with new insulated cladding routinely recoups 70 to 85 percent of its installation cost upon home resale.
How a Professional Siding Installation Is Done in 4 Steps
Discover the four core phases professional exterior contractors follow when installing new siding.
Remove Old Cladding and Inspect Sheathing
Strip away existing siding, pull old nails, and inspect wooden wall sheathing for water rot, mold, or termite damage, replacing soft OSB boards.
Install Weather-Resistant Barrier and Flashing
Wrap the exterior in vapor-permeable house wrap, tape all vertical seams with acrylic flashing tape, and install metal kick-out flashing at roof-wall intersections.
Mount Starter Strips, Corner Posts, and J-Channels
Snap level chalk lines around the foundation perimeter to fasten starter strips, set inside/outside corner posts, and install J-channel trim around windows.
Hang Siding Panels Allowing Thermal Expansion
Fasten siding planks into wall studs using corrosion-resistant roofing nails, centering nails in slots without driving them tight to permit seasonal expansion.
Frequently Asked Questions (8 Questions Answered)
Q1: Can you install new siding directly over old siding?
Contractors can install vinyl over flat wood siding using fanfold insulation, but tearing off old siding is strongly recommended to inspect for hidden framing rot.
Q2: Which siding material lasts the longest?
Fiber cement (Hardie board) and manufactured stone veneer endure 50+ years, resisting rot, termites, and fire, while vinyl lasts 20 to 30 years.
Q3: How do you know when your house needs new siding?
Clear warning signs include warped or cracked boards, peeling interior paint from water intrusion, severe color fading, rotting wood, and rising heating bills.
Q4: Why shouldn't vinyl siding nails be driven in tightly?
Vinyl expands and contracts up to 1/2 inch across seasons; nails must be driven loosely with 1/16-inch clearance so panels can slide freely without buckling.
Q5: Does new siding improve a home's energy efficiency?
Yes, installing insulated vinyl siding or adding 1-inch continuous rigid foam insulation beneath new siding eliminates thermal bridging, cutting utility bills by 10 to 20 percent.
Q6: How long does it take a crew to side a 2,000 sq ft house?
A standard siding crew takes 5 to 9 business days to tear off old siding, install weather barrier wrap, and hang new siding and trim.
Q7: What is the cheapest type of house siding?
Standard hollow-core vinyl lap siding ($4.50 to $7.00 per sq ft installed) is the most economical residential exterior siding material.
Q8: Do I need a building permit to replace siding on my home?
Yes, most municipal building departments require a permit for whole-house siding replacement to ensure compliance with local energy and fire barrier codes.
