Average home exterior is 1,200-2,000 sq ft — measure or estimate all walls minus windows and doors
Scope Notes & Exclusions5 planning notes included with this estimate
- The takeoff quantity shows a 10% planning allowance, while the installed benchmark is applied to net wall area so waste is not priced twice.
- Allow vinyl panels to move for thermal expansion and follow the selected product's fastening instructions.
- Excluded: Hidden sheathing, framing, insect, or water-damage repair
- Excluded: Exterior insulation unless included in a product-specific quote
- Excluded: Insulated backing unless included in the selected product quote

About the Replacement Cost Calculator
Siding replacement transforms your home's curb appeal, weather protection, and energy efficiency. Whether you're upgrading from aging vinyl, switching to fiber cement, or considering brick veneer, our calculator breaks down costs by material, wall area, number of stories, and removal scope — helping you compare options and set a realistic budget.
How We Calculate Replacement Cost
We normalize measured net wall area and apply Fixr's material-specific installed range to that area. Because the cited range already includes base installation, the calculator does not add a second base-labor line. The takeoff still shows a material allowance for ordering, but that allowance is not multiplied into the installed benchmark. When removal is selected, the model adds a weather barrier plus $1–$2 per sq ft for tear-off and disposal. Two-story access adds 15% and three-story access adds 30% to a separate general-labor and removal basis. Permit cost remains a fixed national planning allowance when Location changes. The 60% material / 40% labor regional weighting is a transparent model assumption, not a source-published breakdown.
Factors That Affect Replacement Cost
Key factors affecting siding replacement cost: total wall area (minus windows and doors), siding material (vinyl is cheapest, brick veneer is most expensive), number of stories (scaffolding adds cost), whether old siding must be removed, condition of underlying sheathing (rot repair adds cost), trim complexity (corners, soffits, window surrounds), and regional labor rates.
Published Installed Siding Ranges Used by the Model
These source-published ranges include base installation and apply to net wall area before weather barrier, removal, permit, height access, and regional adjustment. Quote inclusions for trim and accessories still need confirmation.
| Material | Installed range / wall sq ft | Planning takeoff allowance |
|---|---|---|
| Vinyl | $3 – $12 | 10% |
| Engineered wood | $2 – $10 | 10% |
| Natural wood | $2 – $15 | 15% |
| Fiber cement | $5 – $14 | 12% |
| Brick veneer | $3 – $13 | 10% |

What 1,500 and 2,000 sq ft siding projects look like
These examples use exterior wall area, not indoor living area, and come directly from the calculator model.
Example 1 — 1,500 sq ft of one-story vinyl siding with removal. A 10% takeoff allowance produces a 1,650-sq-ft planning purchase quantity, while the installed benchmark is applied once to 1,500 sq ft. The modeled range is $6,900–$24,750, with a midpoint of $15,500: $11,250 for the base installed assembly plus $4,250 for weather barrier, removal/disposal, and permit.
Example 2 — 2,000 sq ft of fiber-cement siding on a two-story home with removal. A 12% takeoff allowance produces a 2,240-sq-ft planning purchase quantity. The installed assembly and separate height-access allowance produce a $13,750–$38,300 range, with a midpoint of $25,700. Change Location before comparing these national figures with local quotes.
Remove the old siding or install over it?
Installing over existing siding removes both the modeled weather-barrier line and the $1–$2 per sq ft tear-off/disposal line, but it is not automatically the lower-risk choice. The old wall must be flat and sound, fastening still has to reach suitable framing or sheathing, windows and doors need correct flashing extensions, and the new assembly must comply with product instructions and local code.
Removal exposes rot, insect damage, missing flashing, and failed weather barrier before they are covered again. For a 2,000 sq ft one-story vinyl project, this model returns a $15,500 midpoint without removal and $20,500 with removal and a new weather barrier—a $5,000 scope difference. Ask each bidder what inspection, flashing, and drainage-plane work is included in either approach.
How to compare siding quotes on the same scope
Give every bidder the same measured wall area and ask them to itemize product line and profile, tear-off, damaged-sheathing allowance, weather barrier, flashing, trim, permits, disposal, and workmanship warranty. Confirm whether the quote includes soffit and fascia or only wall cladding.
A low bid that excludes removal, wrap, trim, or rot repair is not comparable with a turnkey bid. Also ask how change orders are priced: a per-sheet sheathing rate and a written hourly or unit rate make hidden-condition costs easier to control. Compare at least three written quotes after aligning those inclusions.
Replacement Cost by Exterior Wall Area
| Exterior Wall Area | Low | Average | High |
|---|---|---|---|
| 800 sq ft | $3,750 | $8,500 | $13,900 |
| 1,100 sq ft | $5,100 | $11,500 | $18,550 |
| 1,500 sq ft | $6,900 | $15,500 | $24,750 |
| 2,300 sq ft | $10,500 | $23,500 | $37,150 |
| 3,000 sq ft | $13,650 | $30,500 | $48,000 |
| 4,500 sq ft | $20,400 | $45,500 | $71,250 |

Cost basis & data provenance
Scope-matchedThis calculator checks a typical 1,500 sq ft one-story vinyl siding replacement with tear-off against a scope-matched benchmark of $8,500–$20,000; $14,500 average, using Fixr siding-replacement guide (accessed 2026-07-28). Cost data is scheduled for review by 2027-01.
- Fixr — Siding Replacement: $8,500–$20,000 whole-house range; vinyl $3–$12 per sq ft installed; installation labor $1–$4 per sq ft. The default applies the installed vinyl range once to measured wall area, then adds selected tear-off, weather barrier, permit, and disposal scope. It does not add base installation labor twice. Checked 2026-07-28.
