Siding Cost Estimator (region-adjusted)

Last reviewed: 2026-09-27

Researched and written by one person, not an editorial team. I am an independent researcher, not a licensed contractor, and I do not install siding — see the About page for exactly what I do and don't do. This page contains a sidebar lead-capture form; if you submit it, your contact information is routed to a disclosed set of siding-installation companies and/or lead networks, and I am paid for that referral. That disclosure, and the current list of who sees your information, is shown next to the form itself, not buried here.

What this page is: the tool, and the judgment to use it with

This is the companion tool to our deeper cost breakdown, Siding Replacement Cost in 2026. That page is the research — the named regional sources, the whole-house tables, the two manufacturer warranty extractions and the Florida HVHZ code section. This page is the working estimate: a region-adjusted calculator that returns a rough installed range by material and square footage, built from the same sourced ranges as that research (re-verified below, not re-guessed).

Here is the honest framing up front, because it determines how you should read every number on this page and every number in the tool below: a calculator that returns a single price would be lying to you. No tool that keys off material, square footage, and region can know the four things that move an installed siding price more than all three of those combined: whether the old siding has to come off or can be covered over, what condition the sheathing underneath turns out to be in, which company you hire and what their packaged price includes, and whether your house triggers extra code work. What this tool can do honestly is give you a range and a typical figure — a defensible middle so that when a real contractor hands you a number, you have something to compare it against instead of an average pulled from nowhere.

The job of the tool on this page is one narrow thing: square footage × rate per square foot × regional multiplier. The job of the prose below is the work that formula cannot do — explaining why the output is a range and not a price, what it does not count, and how to use the number once you have two or three real bids on the table.

Vinyl $3 $6.13 $12 Most common replacement material nationally.
Fiber cement (James Hardie) $4.7 $9.0 $15 Dominant fiber-cement brand in every regional source we checked.
Engineered wood (LP SmartSide) $3 $7.5 $12 No national aggregator breaks this out separately; typical is a regional-source midpoint, not a national figure.
Aluminum $4 $7.32 $11 Lowest maintenance in most sources, but repainting every 5-10 years is common once the factory finish chalks.
Natural wood / cedar $5 $11.7 $20 Widest spread of any material; cedar premium can run far above this range at elevation (see article).

How this is calculated

Formula: square footage × rate per sq ft × regional multiplier

This is a material-plus-labor unit-cost estimate for a standard re-side. It does not itemize tear-off, sheathing repair, trim, or permits separately -- those are covered, with real dollar ranges, in the Siding Replacement Cost 2026 article.

What this estimate excludes: - Tear-off and disposal of the old siding ($1,000-$3,000 flat, or $0.70-$2.00/sq ft) - Sheathing or structural repair discovered once the old siding comes off - Trim, soffit, and fascia replacement - Building permits (set locally; see the article for two named municipal fee schedules) - Paint / field finishing where the product requires it after installation

Regional multipliers are derived from comparing published regional retail quotes against the national aggregate in our Siding Replacement Cost 2026 article. They are approximate -- actual quotes vary by installer, scope, and project condition.

Sources for these figures

Why the answer is a range and not a price

The tool computes square footage × rate per sq ft × regional multiplier. Each of those three inputs is itself a range or an approximation.

  • The rate is a range per material, and the spread is wide on purpose. The vinyl rate in the tool spans $3–$12 per square foot installed. That is the real spread across the sources behind the companion article: Nebraska's low end (J-Tech Construction & Solar, retrieved 2026-08-08) sits at $3, while Sierra Nevada, Northeast Ohio, and Pennsylvania/WV/Ohio sources all run as high as $12 for the same material (Mr. Honey Do · Tri-Link Contracting, both retrieved 2026-08-08). A single "vinyl costs $X" figure would average away exactly the thing that separates a straightforward ranch from a two-story home with cut-in trim.
  • The regional multiplier is derived, not measured. I re-checked This Old House's 2026 siding guide directly today (retrieved 2026-09-27): it still lists vinyl at $6.13/sq ft and a $12,252 average for a 2,000-sq-ft vinyl home, matching what the companion article reported on 2026-08-08. The tool's regional multipliers (1.0 national baseline, 0.9 Nebraska/Midwest, 1.2 Sierra Nevada/Tahoe/Reno, 1.15 Carolinas fiber-cement market, 1.45 Florida HVHZ) are computed by comparing those regional figures against that national baseline — a judgment I made in the research, disclosed on the tool itself, not a statistic from a government or industry source. Any other "regional" siding calculator you find online is making the same kind of judgment with its own assumptions.
  • The formula assumes a standard re-side, not tear-off complexity. The tool intentionally prices material and labor for the siding itself. It does not add tear-off, sheathing repair, trim, or permits — those are real, common costs, and the next section prices them separately rather than folding them into a number the tool cannot actually know.

Here is what the tool gives you for a concrete case, using the tool's own numbers. 2,000 sq ft of vinyl at the national baseline: the typical figure is 2,000 × $6.13 = $12,260 (This Old House's own 2,000-sq-ft vinyl figure is $12,252 — the tool's formula reproduces it almost exactly), and the range is 2,000 × $3 to 2,000 × $12 = $6,000–$24,000. Move the same job to the Florida HVHZ multiplier and the typical figure becomes roughly $17,777 with a range of $8,700–$34,800. That is real money attached to one jurisdictional line (Miami-Dade and Broward Counties only — see the companion article), not a generic "coastal markup."

The tool prices installation, not ownership

One more honest limit, because it changes how you should weigh two bids that use different materials at similar totals: the tool's formula stops at the installed price. It does not price what the siding costs you afterward. A vinyl job and a fiber-cement job at the same total installed cost are not the same total cost of ownership — fiber cement's manufacturer warranty on the finish is stronger in some respects and weaker in others than vinyl's, engineered wood requires field-painted cut edges as a warranty condition, and aluminum's factory finish typically needs repainting within 5–10 years even though the substrate itself can outlast that. The Siding Materials Compared companion page pulls the actual warranty PDFs for vinyl, fiber cement, and engineered wood and puts the maintenance and warranty terms side by side — read it before you let a lower installed number decide the material for you.

Tear-off vs. over-cladding: the lever the tool can't see

This is the single biggest scope decision in a re-side, and it is the one the companion article identified as driving most of the 3–4x spread between aggregator averages and real regional quotes. The tool prices material and installation labor only; it does not know whether your old siding has to come off first.

  • Tear-off (the more common, and often required, scope). Removing the existing siding before installing new material. Every regional contractor in the companion research prices this as a separate $1,000–$3,000 flat line item, or $0.70–$2.00 per square foot (Peak & Valley Roofing · J-Tech Construction & Solar · Tri-Link Contracting, all retrieved 2026-08-08). On a 2,000-sq-ft job that is $1,400–$4,000 on top of the tool's number.
  • Over-cladding (installing new siding directly over the old material). Cheaper up front because there is no tear-off labor or disposal fee, but it is frequently not warranted by the manufacturer, and it hides — rather than finds — any rot or moisture damage already in the wall. Tri-Link's own framing is blunt about the risk this scope decision carries either way: a "$10,000 re-side can turn into $20,000+" once tear-off exposes rotted sheathing that no bid could have priced in advance.

Because the tool cannot see your wall, use scope as your first bid-filter, exactly the way the companion article recommends: ask each contractor whether tear-off is included, and whether their price assumes the sheathing underneath is sound. A bid that is meaningfully below the others is worth asking about before it's worth celebrating.

What the estimate does not include

Every estimate above — the tool's, and every "average" you'll find online — excludes a specific set of real costs that cannot be known until a job is scoped or started.

  • Sheathing or structural repair (contingent). Not standard, and not knowable in advance. Tri-Link's re-side-turns-into-rot-remediation warning above is the concrete version of this; Mr. Honey Do quotes $500–$3,000+ for structural sheathing repair specifically (retrieved 2026-08-08).
  • Trim, soffit, and fascia. Priced as a separate trade in every regional source: soffit/fascia at $6–$20 per linear foot, window and door trim/J-channel at $500–$2,500 (Mr. Honey Do, retrieved 2026-08-08).
  • Building permits. Set entirely locally. The companion article pulled two real fee schedules: a flat $91.06 minimum building permit in Houston, TX, versus $30.06 plan check + $200.38 building permit/inspection for one-story re-siding in Santa Rosa, CA (City of Houston · City of Santa Rosa, both retrieved 2026-08-08, primary-document extractions). Neither number applies to your city; call and ask.
  • Paint / field finishing. Fiber cement and engineered wood siding are typically sold primed, not finish-painted; field-painting the installed siding runs $1,000–$4,000 as its own line item (Mr. Honey Do, retrieved 2026-08-08) — and for engineered wood, painting exposed cut edges is a manufacturer warranty requirement, not a cosmetic choice (see the companion article's LP SmartSide extraction).

Whether a pre-1978 house triggers the EPA's lead rule — and why the answer is less clean for siding than for windows

If your house was built before 1978, work that disturbs painted surfaces is potentially covered by the U.S. EPA's Renovation, Repair, and Painting (RRP) Rule. For window replacement, the rule is unconditional — the EPA states window replacement and demolition of painted surfaces "are always covered regardless of square footage." I re-checked the EPA's own RRP contractor page directly today (retrieved 2026-09-27, primary-document extraction) to see whether siding gets the same unconditional treatment, and it does not: the EPA's list of example covered activities names "remodeling and repair/maintenance… painting preparation… carpentry… and window replacement" without naming siding specifically, and the rule's general minor-repair exemption — six square feet or less of paint disturbed per room indoors, or twenty square feet or less on the exterior — is not disqualified for siding the way it is for windows.

What that means in practice: a small siding patch job on a pre-1978 house might genuinely fall under the 20-square-foot exterior exemption. A whole-house re-side will disturb far more than 20 square feet of old painted surface and is covered by the general rule for that reason, not because siding is named the way windows are. Either way, the practical guidance is the same as the EPA gives consumers for any pre-1978 renovation: hire a firm with an EPA-certified renovator and ask them to state their lead-safe work plan before signing, rather than assuming a "just siding" job is automatically exempt.

Why a contractor's quote will differ from this estimate

If you take the tool's range out to get bids, expect real numbers to sit above the estimate for reasons that have nothing to do with anyone being dishonest:

  1. The estimate is material-plus-labor; the quote is a packaged service. An installed-sale company's retail price bundles a sales visit, measurement, a crew, warranty backing, and often financing — none of which shows up in a unit-cost model.
  2. Scope is decided per-site, and tear-off/sheathing condition moves the number most, as covered above.
  3. Regional code drives material and fastening, not just labor. Florida's HVHZ wind-load and impact-testing requirements (see the companion article's primary-document code extraction) are the clearest example: the same fiber-cement material, installed to HVHZ spec inside Miami-Dade or Broward County, costs meaningfully more than the identical material installed elsewhere in Florida — which is exactly why the tool's Florida multiplier exists.
  4. Condition is discovered, not predicted. Rot, insect damage, and mold hiding behind old siding only surface once the tear-off starts. Good contractors price the base job and add change orders for what they find.

The useful way to read the gap between the tool and a quote is not "the tool is wrong" or "the contractor is padding the bill." It is: every dollar the quote sits above the estimate should be explainable as scope, condition, code, or packaging. If a contractor can walk you through which of those four buckets each dollar belongs to, the quote is internally consistent even if the total is well above "the average." If they can't, keep asking — and see the companion piece, How to Compare Contractor Bids, for the worked version of that conversation.

How to actually use this number when you're comparing bids

The number the tool gives you is a comparison tool, not a price target. Here is the concrete drill, adapted from the same method the window-calculator sibling page uses, and expanded for the scope question that matters most on a re-side:

  1. Normalize scope first. Ask each contractor whether tear-off is included, or whether they're pricing over-cladding. If one bid is tear-off and another is over-cladding, you are not comparing two prices for the same job — you're comparing two different jobs that happen to use the same material. Put tear-off bids against the tool's number directly, and treat any over-cladding bid as incomplete until you've asked what happens to a rotted board no one can see yet.
  2. Ask what the tool's baseline excluded, explicitly. Make a two-column list — the tool's exclusions (sheathing repair, trim, permits, paint, and on an old house, lead-safe work) — and ask each contractor which of those are in their number and which are "to be determined." A contractor who answers item by item is giving you something a contractor who quotes one lump total is not.
  3. Read the low-end quote with suspicion, not delight. On a normal job, a number at the very bottom of the regional range in the tool usually means undisclosed scope — over-cladding priced as if it were tear-off, or a sheathing-condition assumption nobody stated — not a bargain. A bid that runs 5–10% under the tool's typical figure, with every exclusion named, is usually the more honest one.
  4. Don't average away the reason two bids disagree. If one bid sits below the tool's range and one sits above it, resist the urge to split the difference and call it settled. Find out why. It's almost always scope, condition, or an exclusion — and that's the actual decision in front of you, not the total.
  5. Use the material rate rows to sanity-check a brand switch mid-negotiation. If a contractor proposes swapping your requested fiber cement for vinyl to hit a number, the tool's own rate rows show why that isn't a small substitution: fiber cement's typical rate ($9.00/sq ft) sits nearly 50% above vinyl's ($6.13/sq ft) nationally, and the gap widens further in the Carolinas market where fiber cement is the regional default (see the companion article). A lower total on a different material is not the same quote at a discount.

A worked example: the same 2,000 sq ft, four ways

To make the multiplier concrete, here is one project — 2,000 sq ft of vinyl siding, tear-off scope — run through the tool at four points on the map:

Location Multiplier Typical figure Range
National baseline 1.0 $12,260 $6,000–$24,000
Nebraska / Midwest 0.9 $11,034 $5,400–$21,600
Sierra Nevada / Lake Tahoe / Reno 1.2 $14,712 $7,200–$28,800
Florida HVHZ (Miami-Dade / Broward only) 1.45 $17,777 $8,700–$34,800

Same material, same quantity, same scope — a $6,743 gap between the Midwest and Florida HVHZ typical figures, and the range at either end spans tens of thousands of dollars before a single contractor has walked the property. That spread is not the tool being imprecise; it is the honest range of what "install 2,000 square feet of vinyl siding" actually costs across the country, once you account for labor markets, elevation-driven material stress, and building code.

What we could not verify

  • Whether a specific installer will land within the tool's multipliers. The multipliers are derived from published regional retail quotes and are approximate by design, as disclosed on the tool itself. I cannot verify that any single company's bid in your ZIP code will fall inside them.
  • An up-to-date engineered-wood national aggregate. As the companion article notes, This Old House's 2026 guide does not publish a per-square-foot figure for engineered wood (LP SmartSide); the tool's engineered-wood typical rate ($7.50) is a regional-source midpoint, not a national statistic, and I say so directly on the calculator rather than presenting it as equivalent in kind to the other rows.
  • A single controlling EPA citation stating siding is or isn't exempt. The EPA's contractor-facing RRP page does not name siding in its example list of covered activities the way it names window replacement, and I could not find a second EPA document that closes that gap definitively. I present the 20-square-foot exterior threshold as the operative rule for siding rather than asserting an unconditional-coverage claim I can't back with the EPA's own text.
