Methodology & sources
National range cross-checked against multiple published 2026 cost guides (Angi, HomeGuide, Homewyse, This Old House, Fixr and trade publications) in July 2026.
State adjustment uses an editorial labor-cost index (0.85–1.35 vs national average) — a simplification of real regional variation.
Quality tiers apply published multipliers for material/type differences (Basic vinyl / Mid-range vinyl (Low-E, argon) / Premium vinyl / fiberglass).
Ranges exclude financing, unusual site conditions, and code-upgrade surprises.
