Frequently Asked Questions
How much does window replacement cost?
Window replacement typically costs $300–$1,200 per window installed depending on size, style, and glass package. A whole-home replacement (15–20 windows) typically runs $6,000–$20,000.
How long do replacement windows last?
Quality vinyl windows last 20–40 years. Fiberglass windows can last 40+ years. Wood windows require more maintenance but can last indefinitely with proper care. Always ask about the manufacturer warranty.
Do new windows really save energy?
Yes — replacing single-pane windows with double-pane low-E glass can reduce heating and cooling costs by 10–25%. The savings are most significant in climates with extreme temperatures.
