Spring is the best time to inspect Quebec windows after a tough winter — here is a checklist you can run in under an hour per floor.
Exterior Checklist
- Inspect caulking for cracks — refill where needed
- Clean weep holes at the bottom of frames
- Wash glass with vinegar-water solution
- Check sill flashing for ice damage
Interior Checklist
- Wipe and inspect weatherstripping — replace if compressed
- Lubricate hinges, locks, and cranks with silicone spray
- Look for any new condensation between panes (a failed seal)
- Confirm window operates and locks smoothly
Signs You Need a Professional
Persistent fog between panes, soft frames, or stuck operation are signs the window needs service or replacement. Request a free assessment if you spot any.
Frequently Asked Questions
How often should I caulk?
Every 5–10 years, sooner if you see cracking.
What lubricant should I use?
Silicone spray — never WD-40, which attracts dust.
Can I clean between panes?
No — permanent fog means the inert gas has leaked and the IGU needs replacement.
