Siding Replacement Cost Calculator

Replacing a home's siding typically costs $5 to $14 per square foot installed, so re-siding a typical home with around 1,500 sq ft of siding runs roughly $8,000 to $20,000, and larger homes or premium materials cost more. The material is the biggest factor: vinyl is the most economical (~$6/sq ft), aluminum and engineered wood are mid-low (~$8–$9), wood and fiber cement like James Hardie are pricier (~$10–$12), and stucco is a full system at the high end (~$13). Beyond material, cost depends on the amount of siding (square footage), the house height (two- and three-story homes cost more for staging and access), and removing/disposing of the old siding (a single layer is standard; a double layer or heavy stucco/masonry removal adds cost). Replacement also commonly includes house wrap, new trim and fascia, sometimes insulation board, painting for unfinished materials, and permits. A ~$3,000 project minimum applies. Because re-siding removes the old siding and installs new, it differs from a repair — enter your area, material, and removal above for a localized estimate.

The best material balances budget, durability, maintenance, appearance, and climate. Vinyl (~$6/sq ft) is the most popular and economical — low cost, never needs painting (just occasional cleaning), many colors, decent durability, though it can crack in extreme cold or warp in intense heat and reads as a mid-tier look. Aluminum/metal (~$8) is durable, fire- and insect-resistant, and low-maintenance, but can dent and the finish may fade. Engineered wood like LP SmartSide (~$9) gives a real-wood look with better durability and lower cost than natural wood, but needs periodic painting. Natural wood/cedar (~$10) is beautiful and classic with great curb appeal but the highest-maintenance (regular staining/painting to prevent rot and insects). Fiber cement like James Hardie (~$12) is very popular for durability — fire, rot, and insect resistant, holds paint well, mimics wood, and lasts decades, though it's heavy and labor-intensive to install. Stucco (~$13) gives a seamless look and is durable in the right (drier) climate but is a specialized multi-coat system that can crack. For low cost and maintenance, vinyl; for durability and a premium look, fiber cement; for natural beauty, wood or engineered wood; stucco for its specific aesthetic. This calculator lets you compare all six.

It depends on how widespread the damage is, the siding's age and condition, and your goals. Repair makes sense when the damage is localized — a few cracked, loose, or damaged panels in one area — and the rest of the siding is sound; fixing just those sections is far cheaper. Full replacement (re-siding) is the better call when damage is widespread, the siding is old and deteriorating broadly (fading, warping, cracking, rotting in many places), there's significant moisture, rot, or mold behind it, the siding is at end of life, you want to upgrade the material, look, or energy efficiency, or you're repeatedly patching the same siding. A key practical issue is matching — with repairs, matching the color and profile of older or faded siding can be hard, so a patch may stand out, sometimes pushing toward re-siding a whole wall or the house for a uniform look. Re-siding is also a chance to add a moisture barrier and insulation, fix hidden issues, and refresh curb appeal and value. If damage affects a small portion and you can match it, repair; if it's failing broadly, unmatchable, or you want an upgrade, replacement is usually the smarter investment. This calculator estimates full replacement; for isolated damage, see the siding repair calculator.

In most cases yes — removing the old siding (tear-off) is the standard, recommended approach for a quality replacement, and the removal is built into the cost. Tear-off is preferred because it lets the contractor inspect the wall sheathing and structure underneath for damage — rot, mold, water intrusion, and pest damage are common behind failing siding — repair any issues, install or replace the house wrap/moisture barrier properly, and start with a clean, sound surface, resulting in a better, longer-lasting, warranty-compliant installation. It's required for materials like fiber cement and stucco and whenever there's existing damage or multiple layers. The downside is the labor and disposal cost, which is higher for heavy removals (stucco, masonry, or multiple layers). Installing over existing siding (an overlay) is sometimes possible for certain materials and saves tear-off cost, but you can't inspect or repair what's underneath (hidden moisture/rot stays trapped), it adds thickness that affects trim and windows, and it can void warranties or violate code — so it's generally not recommended, especially if the existing siding has problems. This calculator includes removal in the estimate, with adders for double layers or heavy stucco/masonry.

Yes — re-siding is one of the best opportunities to improve your home's energy efficiency, mainly by adding insulation and a proper moisture/air barrier while the walls are exposed. When the old siding comes off, you can add a continuous layer of rigid foam insulation board (insulated sheathing) under the new siding, which raises the wall's R-value and reduces thermal bridging; install or upgrade the house wrap to block air infiltration and manage moisture; and choose insulated siding (some vinyl comes with foam backing integrated). These reduce drafts and heat loss/gain, can lower energy bills, and improve comfort and even noise. The siding material itself has a smaller direct insulation value — it's the assembly (insulation board + air barrier + siding) that matters. Properly sealing and flashing around windows, doors, and penetrations during the re-side tightens the envelope further. The added cost of insulation board and house wrap (both add-ons here) is often worthwhile for the long-term savings and comfort, and may qualify for energy rebates in some areas. Because doing it during a re-side is far cheaper than retrofitting later, it's worth discussing continuous insulation and a quality air/moisture barrier with your contractor.

Both significantly affect the total. Square footage: since siding is priced per square foot, a larger home with more exterior wall area simply needs more material and labor, raising the cost proportionally — so measuring the actual wall area (and accounting for the home's shape) is key to an accurate estimate. Number of stories/height: a single-story home is the easiest and cheapest to side because most work is reachable from the ground or short ladders, while two-story and especially three-plus-story homes cost more per square foot because the upper walls require taller ladders, scaffolding, or staging, which adds labor, time, safety measures, and equipment — working at height is simply slower. Complexity matters too: many corners, gables, dormers, peaks, windows, and architectural details require more cutting, fitting, trim, and detail work (and generate more waste) than simple flat walls, so an intricate house costs more than a boxy one of the same square footage. Accessibility around the home (landscaping, tight spaces, obstacles) can also add. This calculator adjusts for one-, two-, and three-plus-story homes to reflect the access and staging differences, and the square footage you enter drives the base cost.

Yes — siding replacement is consistently one of the better home improvements for return on investment and curb appeal, often recouping a substantial portion of its cost and making a home more attractive and sellable. New siding dramatically improves the exterior appearance (curb appeal is a major driver of buyer interest and first impressions), signals a well-maintained home, and addresses a component buyers scrutinize — old, damaged, or dated siding is a red flag, while fresh siding is a selling point. Cost-vs-value reports frequently rank siding replacement among the top exterior projects for ROI, with fiber cement and vinyl often recouping roughly 60–80% of the cost at resale (figures vary by year, region, and material), and manufactured stone veneer and quality fiber cement tend to perform especially well. Beyond resale, new siding adds functional value: better weather and moisture protection, potential energy efficiency gains with added insulation, lower maintenance (vinyl or fiber cement vs. old wood), and durability. The value depends on the material and quality, the condition of the old siding, and execution — choosing a material and color appropriate to your home and neighborhood maximizes the benefit. The combination of strong ROI, curb appeal, protection, and reduced maintenance makes it a worthwhile investment.

Re-siding an average home typically takes about one to two weeks, though it varies with size, height, complexity, material, and weather. A smaller or simpler home might be done in several days; a larger, taller, or more architecturally complex home takes longer, and some materials add time. The process includes setup (and staging/scaffolding for multi-story homes), tearing off and disposing of the old siding, inspecting and repairing the sheathing underneath, installing or upgrading the house wrap/moisture barrier (and any insulation board), then installing the new siding, trim, corners, and fascia, plus finishing around windows, doors, and penetrations — and painting if the material requires it. Material matters: vinyl installs relatively quickly; fiber cement is heavier and more labor-intensive (and may need painting), taking longer; wood needs finishing; and stucco is a multi-step process (lath, base coats, finish coat, with curing time between) that takes the longest. Discovering and repairing hidden damage behind the old siding adds time, as does weather — exterior work, especially stucco and painting, needs dry conditions. Most re-sides keep the home weather-protected by working in sections. Your contractor can give a firm schedule after assessing the home's size, height, material, and condition.
