Possibly — most 1995+ windows came with 10-20 year IGU warranties from Pella, Jeld-Wen, Marvin, Andersen, Loewen, North Star, Vinylbilt, or Polar Window. Check original paperwork or call the installer. If covered, IGU is FREE and you pay only labour.
Repair: window under 20 years, frame sound, modern energy-rated. Replace: frame rotted, window 25+ years old, single-glazed or first-gen thermal, or doing whole-house energy retrofit (often eligible for Canada Greener Homes Grant up to $5,600).
IGU only (foggy seal): $385-$1,050 — about 25-40% of full window replacement ($1,200-$3,200). Hardware repairs (cranks, balances, latches) $85-$285 — about 5-15% of replacement. Big savings if frame is sound.
