Siding Installation Cost Calculator

Siding installation typically costs $5,000 to $20,000 for an average home, with most homeowners paying around $8,000 to $15,000 — a small home in vinyl can be $5,000–$8,000, while a large home in premium fiber cement, wood, or metal (with tear-off and extras) can top $20,000–$35,000+. On a per-square-foot basis, siding runs about $5 to $12+ installed depending on the material. The main drivers are the wall area (an average home has ~1,500–2,500 sq ft of siding), the material (vinyl ~$5/sq ft cheapest, engineered wood ~$7.50, fiber cement ~$9.50, natural wood/metal ~$12), the installation type (new construction cheapest, standard baseline, tear-off + replace priciest), and the home's stories/access (multi-story needs scaffolding). A ~$2,000 project minimum applies. Add-ons like insulated backing, a house wrap, new gutters, trim, and sheathing repairs add on top. Enter your area, material, and install type above for a localized estimate.

The common options, from budget to premium: Vinyl (~$5/sq ft) is the most popular — cheap, low-maintenance (color is molded throughout, so no painting), and available in many styles, though it can crack in extreme cold and looks less premium than some. Engineered wood like LP SmartSide (~$7.50) gives the look of real wood with better durability and stability, is lighter and easier to install than fiber cement, and sits mid-range, but needs periodic painting. Fiber cement like James Hardie (~$9.50) is very durable and long-lasting, fire- and rot-resistant, holds paint well, and mimics wood convincingly — a premium, high-value choice, though heavy to install and requiring repainting over time. Natural wood (cedar) is beautiful and authentic but expensive and high-maintenance (regular staining/sealing) and prone to rot and insects. Metal (steel or aluminum) is durable, fire-resistant, low-maintenance, and modern-looking, though it can dent. Choose by budget, maintenance tolerance, appearance, and climate — vinyl for value, fiber cement for durability and resale, wood or metal for a specific look.

In many cases removing (tearing off) the old siding first is the better practice, though installing over existing siding can save money in the right situation. Installing over existing (re-siding over) — common with vinyl over sound old siding — skips the tear-off labor and disposal, so it's cheaper and faster, but it adds bulk, can trap moisture, prevents inspecting the sheathing for hidden rot or damage, and may not meet some materials' warranties or local code. Tearing off first costs more (labor plus disposal) but lets the crew inspect and repair the wall sheathing, install a proper house wrap/moisture barrier, and set the new siding on a clean, even substrate — the key advantages, since hidden water damage behind old siding is common and important to catch. For the longest-lasting result, and any time there's a concern about moisture or the wall's condition, tear-off is generally preferred. Fiber cement and other premium materials often require it; vinyl is more often installed over. This calculator includes new-construction, standard, and tear-off + replace options plus a rotten-sheathing repair add-on.

House wrap (a moisture barrier like Tyvek) is the layer that goes between the wall sheathing and the siding, and it's one of the most important — and most overlooked — parts of a siding job. Siding sheds most water, but wind-driven rain and condensation still get behind it; the house wrap is what actually keeps that moisture from reaching the sheathing and framing, where it causes rot, mold, and structural damage. It also blocks drafts and improves energy efficiency while still letting the wall breathe so trapped moisture can escape. Skipping or poorly lapping the house wrap is a leading cause of hidden water damage that shows up years later as soft sheathing or interior mold. This is exactly why tearing off old siding is valuable — it exposes the wall so a proper, continuous, correctly-lapped house wrap can be installed. This calculator includes a house wrap/moisture barrier add-on; on a full re-side it's a small line item that protects the entire wall assembly, so it's never the place to cut corners.

It depends heavily on the material. Vinyl lasts about 20 to 40 years depending on quality, climate, and sun exposure — durable and low-maintenance for its cost. Engineered wood lasts roughly 20 to 30+ years with periodic painting. Fiber cement is one of the longest-lasting options at 50 years or more, thanks to its resistance to rot, insects, fire, and weather (with occasional repainting). Natural wood can last 20 to 40+ years but only with diligent staining and sealing — neglected, it deteriorates far faster. Metal siding lasts 40 to 70+ years and is low-maintenance (aluminum won't rust; steel is very durable but can rust if the coating is breached). Brick and stone can last the life of the home. Across all materials, lifespan is stretched by quality installation (especially good moisture management), a suitable climate, and regular maintenance, and shortened by harsh weather, poor installation, and neglect. Fiber cement and metal offer the best longevity if you're optimizing for decades of service.

Yes — siding replacement consistently ranks among the home improvements with the best return on investment, often recouping 60–80%+ of its cost depending on the material and market. The value comes mostly from curb appeal: siding covers most of the home's facade, so fresh, attractive siding transforms the first impression and signals a well-maintained, updated home, which strongly influences buyer interest. It also removes a red flag — old, damaged, or failing siding reads to buyers as a looming repair expense, so replacing it eliminates that concern. New siding (especially with added insulation and a proper house wrap) can improve energy efficiency too, another selling point. Premium, durable materials like fiber cement tend to add the most value and have the best ROI, while a quality vinyl re-side is a strong, cost-effective option. To maximize the return, choose a material and color that suit the home and neighborhood, ensure quality installation, and fix any underlying issues — over-improving a modest home returns less.

Home height is a real cost factor because siding is installed across the whole exterior, and working at height is slower, riskier, and needs more equipment. A single-story home is the easy baseline — much of the work is reachable from the ground or short ladders. A two-story home adds about 15% because the crew needs scaffolding or lifts to safely reach the upper walls, gables, and eaves, which takes setup time and slows the pace. Three-plus stories or homes with difficult access (steep lots, tight spaces, complex rooflines) add about 30% for the extra staging, safety measures, and careful work high off the ground. Complexity compounds this: many corners, dormers, and architectural details mean more cutting, fitting, and detail work regardless of height. So a tall or cut-up home costs more to side than a simple single-story of the same wall area, which is why this calculator scales the estimate by the home's stories and access.

Siding an average home usually takes about 1 to 2 weeks, though it varies with size, material, tear-off, height, and weather. A small home might be done in a few days; a large, tall, or architecturally complex home — or one in a heavy material like fiber cement — can take 2 to 3 weeks. The process is: prep the walls (and tear off old siding if applicable), inspect and repair the sheathing, install the house wrap/moisture barrier, then install the siding from the bottom up and around openings, followed by trim, fascia, soffit, and accessories, and cleanup. Tear-off adds a day or more (plus any repairs found underneath), fiber cement and intricate materials install slower than vinyl, multi-story homes need scaffolding setup, and weather matters since it's exterior work — rain and extreme temperatures cause delays. A larger crew speeds it up. Your contractor can give a firm schedule based on the home's size, material, height, and prep needed.
