Repair makes sense for a contained failure
A serviceable window with one failed sealed unit, worn operator or adjustment problem may be a good repair candidate. The frame, sash and installation should otherwise remain sound.
Ask whether the part is available and whether repair restores normal operation or merely keeps the window usable for a short period.
Contained problem
One repairable component has failed while the surrounding window remains serviceable.
Widespread decline
Several parts, seals or openings are failing and repairs may continue to accumulate.
Parts availability
Discontinued hardware can make an otherwise small repair impractical.
Project goals
Style, comfort, glass area and renovation plans may justify looking beyond the immediate symptom.
Replacement addresses system-wide decline
Rot, widespread air leakage, recurring water entry, multiple hardware failures or extensive seal failure may make repeated repair less attractive.
Replacement can also support a planned change in style, glass area or operation. Those design goals should be distinguished from claims that every older window must be replaced.
Compare the time horizon
Consider how long you expect to remain in the home, whether other renovations are planned and whether several matching windows are approaching the same condition.
A written comparison should include complete installation and finishing scope. Repair and replacement prices are not comparable if one leaves unresolved work around the opening.
Details that make a repair request more useful
- What exactly has failed?
- Which parts remain after the repair?
- Are similar windows developing the same issue?
- What complete work is included with replacement?
