Window installation vs door installation
Both improve energy efficiency and curb appeal, but window and door installation projects differ in cost, ROI, and urgency. Compare to prioritize your home improvement budget.
Window replacement costs $300–$1,200 per window ($6,000–$18,000 for a full house), while interior door installation runs $200–$600 per door. Entry door replacement is $1,000–$4,000+ for a high-quality exterior door. Windows have a bigger impact on energy efficiency (10–25% reduction in heating/cooling bills) because they're the largest source of heat loss — a single-pane window loses 10× more heat per square foot than an insulated wall. Windows return 60–70% at resale. Entry doors return 90–100%+ — the highest ROI of any exterior project. Interior doors are purely cosmetic and return minimal value. If your home has old single-pane or failed-seal windows AND a dated entry door, prioritize windows first for energy savings, then upgrade the entry door for maximum curb appeal at resale.
