Post-Construction Cleaning: The Step-by-Step Pro Method

 

(How to Turn a Dusty Construction Zone into a Spotless Space – Contractors Won’t Tell You These Tricks!)

Why Post-Construction Cleaning is Different

After renovations, you’re not dealing with ordinary dirt but:
⚠️ Microscopic silica dust (hazardous when inhaled)
⚠️ Adhesive residues (from flooring/tiles)
⚠️ Paint overspray (on windows, fixtures)
⚠️ Drywall dust (clogs HVAC systems)

This proven 3-phase system is used by cleaning companies charging $300-$800 per job.

PHASE 1: DUST ARMAGEDDON (Days 1-2)

Tools You’ll Need:

• HEPA-filter vacuum ($200+ investment, but critical)

• Microfiber mop with telescopic pole

• Magnet dust mop (for ceilings/walls)

• Air scrubber (rent for $50/day)

Step-by-Step:

1. Ceilings First

   • Use an extendable duster on fan blades, ducts, and light fixtures

   • Pro Trick: Wrap HVAC vents with cheesecloth to prevent recirculation

2. Walls & Windows

   • Wipe down with tack cloth (sticky cheesecloth for fine dust)

   • For paint spots: Razor blade + glass cleaner

3. Floors

• NEVER sweep dry dust (spreads particles)

• Vacuum with HEPA filter, then damp mop

PHASE 2: HARD SURFACE DECONTAMINATION (Day 3)

Problem Areas & Solutions:

Surface	Challenge	Solution
Hardwood	Gypsum dust in grooves	TSP rinse (1/4 cup per gallon)
Tile	Grout haze	Nylon brush + sulfamic acid
Countertops	Silicone residue	Rubbing alcohol + plastic scraper

Pro Tip:

For stubborn adhesive (vinyl flooring, stickers):

• Heat with a hair dryer for 30 seconds

• Peel with a putty knife

• Remove residue with Goo Gone

PHASE 3: FINAL TOUCHES (Day 4)

Last Steps Before Inspection:

1. HVAC Blowout

   • Replace filters

   • Run the vent vacuum attachment

2. Final Air Purge

   • Run air scrubbers 48 hours post-cleaning

   • Place bowls of activated charcoal to absorb VOCs

3. White Glove Test

• Check:

• Inside electrical outlets

• Behind appliances

• Top of door frames
