What is the difference between full-frame and insert window replacement?

Full-frame replacement removes the entire existing window, including the nailing flange and frame, down to the rough opening. It allows inspection and repair of any hidden water damage and provides the best air seal. Insert replacement installs a new window unit inside the existing frame. It is less expensive but preserves the existing frame, which may have hidden rot. Hamilton Exteriors recommends full-frame replacement for most Hayward homes, especially those built before 1990.

How do I know if I need to replace or repair my windows?

Replace if: windows are 20 or more years old, frames are rotting or warped, seals have failed (fog between glass panes), or you feel drafts even when windows are closed. Repair if: the damage is isolated to hardware, weatherstripping, or a single pane of glass, and the frames are structurally sound. A professional inspection can clarify the right path.
