SIDING PLANNING TOOL / CSLB #1117562

Siding Cost & Materials Calculator

Estimate a siding planning quantity and budget from measured wall area, material, stories, access, trim, and selected scope options—then see what a contractor must verify before the number becomes a written proposal.

Use the Calculator
CURRENT METHOD — NOT A BID

10% planning allowance

The calculator adds 10% to the entered wall area before applying the configured material, story, access, and scope factors. Selected trim and wall-system options are then added separately.

MEASURE FIRST

Calculate a siding planning range

Use measured exterior wall area—not floor area. Select only options you want included. The result is a budgeting aid; concealed conditions, field measurements, product requirements, permits, and a written scope still need verification.
Before calculatingMeasure each elevation, include gables, document openings and trim, and avoid adding waste twice.

TRANSPARENT CALCULATION METHOD

How the calculator assembles the planning result

Inputs verified against the live calculator on July 23, 2026. Rates are current US Construction Remodeling Corp. operational planning inputs. They are not a third-party market survey, guaranteed price, or substitute for a measured written proposal.

1

1 · Planning area

Entered wall area × quantity × 1.10. The 10% allowance helps cover cuts and normal planning waste; product-specific ordering still requires a takeoff.

2

2 · Material base

Vinyl $16, engineered wood $22, fiber cement $20, or wood $24 per waste-adjusted square foot before scope, story, and access factors.

3

3 · Complexity factors

Scope: new installation ×0.92, replacement ×1.00, partial ×1.08. Stories: ×1.00/1.12/1.24. Access: ×1.00/1.10/1.22.

4

4 · Options & range

Trim $16/ft; house wrap $1.20/waste-adjusted sq ft; insulation board $2.10/waste-adjusted sq ft; paint $5/measured sq ft; tear-off $3/measured sq ft; permit allowance $450. Result range: ±15%.

MEASURED EXAMPLE

A 1,000-square-foot fiber-cement example

One-story replacement · easy access · no selected add-ons:

1,000 sq ft × 1.10 = 1,100 planning sq ft
1,100 × $20 = $22,000 estimated total
Displayed range: $18,700–$25,300

Adding standard access, trim, house wrap, tear-off, paint, insulation board, a permit allowance, or difficult conditions raises the result. A written proposal should show which of those items are actually included.

WHAT THE FORM CANNOT SEE

Six checks before relying on the result

Confirm whether the input is gross or net area, how gables and openings were treated, and whether quantity represents one house or repeated matching areas.

Identify the existing cladding, number of layers, fastening surface, visible damage, demolition method, disposal, and what must be opened before concealed conditions can be confirmed.

Coordinate WRB, flashing, kick-outs, windows, doors, penetrations, decks, roof-to-wall intersections, drainage paths, and repairs as one wall assembly.

Measure trim separately and specify corners, openings, utility blocks, transitions, factory finish or field paint, preparation, coats, cut-edge treatment, and touch-up.

Tall walls, slopes, tight side yards, landscaping, utilities, staging, lifts, occupied areas, and limited material access can materially change labor and protection.

Verify permit, planning, historic-review, inspection, product-documentation, cleanup, change-order, warranty, and closeout requirements for the address and scope.

Exterior siding, door, window, and trim transitions

Sacramento lists siding as permitted work

The City's required permits page names siding. Confirm the address, exact scope, historic status, related work, and current application path before demolition.

Permit and plan review are separate

Sacramento's plan-check table says residential siding generally does not require plan review, while commercial siding does. That does not remove the permit requirement.

Exterior changes may involve planning review

The City's Site Plan and Design Review page provides exterior-siding and historic-property pathways. Verify the address and appearance change.

The 2025 California codes are in effect

The California Building Standards Commission states that the 2025 Title 24 codes are effective January 1, 2026 through December 31, 2028.

Pre-1978 painted surfaces need lead-safe planning

The EPA's Renovation, Repair and Painting rule can apply when paid renovation work disturbs painted surfaces in many pre-1978 homes, subject to scope and exemptions.

The written contract must match the scope

California home-improvement projects over $500 generally require a written contract. Use the CSLB contract guidance to document products, quantities, permits, price, schedule, changes, cleanup, and warranties.

TURN THE RESULT INTO A WRITTEN SCOPE

Four checks before comparing siding proposals

Verify California contractor license #1117562 on the CSLB record. Compare proposals only after measurements, products, demolition, repairs, wall-system details, finish, exclusions, permits, and closeout requirements match.
1

Measured quantities

Named elevations, gross or net wall area, deductions, waste, gables, exact siding, profile, trim length, accessories, fasteners, finish, and quantity-change method.

2

Removal & repairs

Demolition, disposal, protection, substrate review, included allowance, unit prices, photo documentation, approval threshold, and stop-work conditions.

3

Complete wall assembly

WRB, flashing, openings, penetrations, clearances, fastening, trim, sealants, coating, related work, permits, and inspections.

4

Contract & closeout

Selections, lead times, payment milestones, written change orders, cleanup, lien releases, product records, warranties, and final documents.

HOMEOWNER QUESTIONS

Siding calculator FAQ

The calculator estimates a planning quantity and budget from the wall area, material, project scope, stories, access, trim length, and selected options. It adds a 10% planning allowance to the entered wall area, applies the configured material and complexity factors, adds selected options, and displays an uncertainty range of 85%–115% of the estimated total.

The current configured material inputs are $16 per waste-adjusted square foot for vinyl, $22 for engineered wood, $20 for fiber cement, and $24 for wood. These are US Construction Remodeling Corp. operational planning inputs—not market averages, material-only prices, or binding quotes. The calculator can also add trim, house wrap, insulation board, paint, tear-off, and a permit allowance.

Enter measured exterior wall area, not interior floor area. Measure wall sections and gables, then decide whether your figure is gross area or already subtracts large openings. The calculator applies a separate 10% planning allowance, so do not add the same waste twice.

A calculator cannot confirm hidden rot, sheathing or framing damage, multiple existing layers, hazardous-material controls, complex flashing, product-specific requirements, difficult staging, historic review, or exact permit and inspection conditions. A measured site assessment and written scope control the actual proposal.

The City of Sacramento lists siding among work that requires a permit. Its current plan-check table says residential siding generally does not require plan review, while commercial siding does. Permit, planning clearance, historic review, and plan review are separate questions, so verify the address and scope before demolition.

Compare written proposals that identify elevations and quantities, exact products, demolition, disposal, substrate review, repair pricing, water-resistive barrier and flashing details, trim, finish, access, permit responsibility, inspections, cleanup, exclusions, change orders, and written warranties.

No. The result is an early planning estimate. It is not a bid, contract, permit approval, inspection result, engineering decision, warranty, financing offer, schedule commitment, or acceptance of a project. Contact details are requested only if you choose to continue and ask for the estimate to be sent.
