What to Expect During a Full-Frame Window Replacement

Why Full-Frame Replacement Is Different

When a crew does a full-frame replacement, they remove the entire old window assembly, not just the sash. The old frame, the surrounding trim, and the weatherproofing layers usually get removed so the opening can be rebuilt correctly.
