Post-Construction Cleaning Checklist for Markham Offices (Dust-Free in 1 Day)
Updated: Aug 24
Construction dust clogs HVAC, coats glass partitions, and embeds in carpets—making Markham offices unbreathable. This 1-day checklist gets spaces client-ready.
Step 1: Dry Dust Everything
HEPA vacuum ceilings, lights, vents first. Construction dust is fine—regular vacuums spread it. Start top-down.
Step 2: Glass Partitions & Windows
Microfiber + glass cleaner (ammonia-free). Top-bottom streaks avoided. Dry with second cloth immediately.
Step 3: Carpet Deep Clean
HEPA vacuum → baking soda sprinkle (30 mins) → vacuum again. Neutral carpet shampoo high-traffic only.
Step 4: Trim, Baseboards, Door Frames
Damp magic eraser for paint splatter. White vinegar solution for greasy fingerprints. Detail corners.
Step 5: Final Air Reset
Open windows 30 mins, run HVAC fan (clean filter first). Place activated charcoal bags in corners overnight.
Common Post-Reno Mistakes
Wet cleaning first (dust turns to mud).
Missing HVAC (dust recirculates weeks).
Skipping trim (looks dirty even when floors shine).
