Isolated lock, balance, seal, or glass failures usually deserve a repair estimate first.
When many openings leak, frames distort, insulated glass fails broadly, or the same problems recur, replacement may offer a more durable solution.

When repair is the logical first step
When the frame is stable and failure is limited to serviceable hardware, seals, or one glass unit, repair can restore function with less disruption.
For newer products, check labels and written manufacturer warranty terms before authorizing work.
Signals that justify a replacement comparison
Rot, severe distortion, repeated leakage, obsolete hardware, unsafe operation, or broadly inadequate performance justify a replacement comparison.
Water can also originate in wall or roof interfaces, so diagnose the source before assuming a new window will solve it.
Turn quotes into comparable scopes
Repair quotes should list parts, glass, seals, labor, and structural exclusions. Replacement quotes should also define removal, finishes, disposal, and permits.
Do not decide from one vague total; compare which problems each proposal actually resolves.
