Applying waste automatically to every service can overstate labor and removal. Use each contractor’s stated billing quantity when it differs."},{"question":"What is excluded from field siding area?","answer":"Field siding area does not measure corners, starter, J-channel, window and door trim, frieze, soffit, fascia, flashing, housewrap, fasteners, insulation, or repair. Those accessories depend on elevation geometry and system details, so include them through a separate takeoff or fixed quote."},{"question":"Should windows and doors be subtracted?","answer":"Subtract measured openings for net field area, but maintain an appropriate material allowance because cuts around openings may not be reusable. Small openings may not reduce the purchase by a full carton. Their flashing and trim often add labor even while reducing cladding area."},{"question":"How should siding bids be compared?","answer":"Require the same product, profile, color, wall preparation, drainage plane, flashing, insulation, trim, fasteners, removal, disposal, repair allowance, access, permit, tax, warranty, and cleanup scope. Investigate quantity and exclusion differences instead of comparing only cost per square foot."}],"sources":[{"name":"Federal Trade Commission — How To Avoid a Home Improvement Scam","url":"https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam","note":"Federal consumer guidance on contractor checks, multiple written estimates, itemized scope, contracts, and payment practices."},{"name":"U.S. EPA — Lead Renovation, Repair and Painting Program","url":"https://www.epa.gov/lead/renovation-repair-and-painting-rrp-program-consumers","note":"Federal guidance for renovation work that may disturb lead-based paint in pre-1978 housing, including painting and window replacement."}],"defaultCalculation":{"inputs":{"area":2000,"waste":10,"materialRate":0,"laborRate":0,"removalRate":0,"fixedCosts":0,"contingency":10},"result":{"value":"Add local quotes","unit":"to build budget","label":"Siding project budget","lines":[{"label":"Field siding purchase area","value":"2,200 sq ft"},{"label":"Field siding material","value":"Not entered"},{"label":"Installation labor","value":"Not entered"},{"label":"Removal and disposal","value":"Not entered"},{"label":"Contingency","value":"Not added"}],"summary":"The physical scope is calculated, but no budget is shown until you enter at least one current local price or written quote.","note":"Field area does not price corners, starter, channels, soffit, fascia, housewrap, flashing, insulation, sheathing or rot repair, hazardous-material work, permits, tax, or landscaping protection unless fixed or unit quotes include them."}},"reviewedOn":"2026-07-24","disclaimer":"Planning estimate only.
