Insert vs Full-Frame Replacement
Insert (pocket) replacement fits a new window into the existing frame—lower cost and less disruption. Expect to pay $300–$700 per window. Full-frame replacement removes everything down to rough framing, costs $800–$1,500+ per window, and is required when frames are rotted or when changing window size.

What is the best window frame material?
Vinyl is the most popular—low maintenance and affordable. Fiberglass is the most durable. Wood offers the best aesthetics for historic homes but requires more upkeep.
