Frequently Asked Questions
How much does window replacement cost?+
Standard double-hung vinyl replacement windows run $150–500 per unit plus $75–150 labor = $225–650 installed. Casements cost $275–800 installed. Bay windows are $800–3,000+. A 10-window house typically runs $3,000–8,000 for mid-grade vinyl windows with professional installation.
What is the standard window size?+
The most common residential window is 36"×48" (double-hung). Standard widths run 24–48 inches; standard heights 36–60 inches. Rough opening is typically 0.5" larger than the window unit on each side. Always measure the rough opening before ordering — units are sized to fit the rough opening.
How long does window installation take?+
Insert replacement (same frame, new sash): 1–2 hours per window. Full-frame replacement: 2–4 hours per window. Bay or bow windows: 4–8 hours. A 2-person crew can typically replace a full house of 10–15 standard windows in one day. Skylights add half a day each.
What window type is most energy efficient?+
Casement and awning windows compress tightly against the frame when locked, eliminating air gaps. Pair with triple-pane glass, low-E coating (U-factor ≤0.30), and argon gas fill for maximum efficiency. ENERGY STAR-certified windows reduce heating and cooling costs 12–33% versus single-pane.
