Start with the actual failure
Identify whether the problem is glass, hardware, sash, frame, flashing, air sealing, water intrusion, or appearance. The right repair depends on the cause.
Frame condition is a dividing line
If the frame is structurally sound, repair or insert replacement may be possible. Rot, distortion, chronic water damage, or poor original installation can justify full-frame work.
One failed unit is different from a whole-house pattern
A single failed seal can be handled individually. Similar failures across many windows may support a coordinated project.
Consider long-term plans
If you plan to stay in the home, weigh comfort, maintenance, operation, appearance, and future service in addition to immediate cost.
