Quick answer
Repair or Replace Windows? works best when the current fault, age, repair estimate, repeat failures and replacement scope are compared together. One threshold by itself is not enough to justify replacement.
Why age alone is not enough
Use age, failure type, frame condition and number affected. The useful interpretation comes from the combination of facts, not from repeating a generic answer. Identify the failed component before assuming full replacement.
Repair cost versus remaining life
Compare the current failure with the wider condition of the system. Repair cost, repeat failures, age, efficiency, comfort and the scope of replacement belong in the same decision; replacing solely because of age can be as misleading as repairing repeatedly without considering remaining life.
Repeat failures and performance
Use age, failure type, frame condition and number affected. The useful interpretation comes from the combination of facts, not from repeating a generic answer. Identify the failed component before assuming full replacement.
When replacement becomes more rational
Compare the current failure with the wider condition of the system. Repair cost, repeat failures, age, efficiency, comfort and the scope of replacement belong in the same decision; replacing solely because of age can be as misleading as repairing repeatedly without considering remaining life.
What to compare in quotes
Compare like-for-like scope. A useful quote should make it clear what is being repaired or replaced, what is excluded, what could change after inspection and what warranty or follow-up is included.
