Deep Cleaning a New Construction Home Before Move-In

New Doesn't Mean Clean

You just closed on your brand-new home in Jacksonville — maybe in one of the new developments in Nocatee, eTown, or RiverTown. The counters gleam, the paint is fresh, and everything smells new. But here's what most homeowners don't realize: new construction homes are some of the dirtiest spaces you'll ever encounter.

Behind that fresh-paint smell is a layer of fine construction dust that has settled into every vent, every cabinet, every electrical outlet. After cleaning dozens of newly built homes across Northeast Florida, our team can confirm that a pre-move-in deep clean isn't optional — it's essential for your family's health and comfort.

What's Lurking in Your New Home

Builders do a "broom clean" before handover. That means they sweep the floors and wipe the obvious surfaces. What they don't do is any of the following:

• Construction dust: Fine particulate from drywall sanding, concrete cutting, and wood work settles everywhere — inside cabinets, on top of doorframes, inside HVAC ducts, behind appliances. This dust is 60-70% silica and can irritate lungs and skin.
• Drywall dust: The most pervasive substance in any new build. It's alkaline, which means it can irritate skin and eyes. It also finds its way into every crack and crevice.
• Chemical off-gassing: New paint, adhesives, cabinets, and flooring release volatile organic compounds (VOCs). The EPA notes that VOC levels inside new homes can be 2-5 times higher than outside — and Jacksonville's heat accelerates off-gassing.
• Sawdust and wood shavings: Hidden behind baseboards, inside cabinets, and in ceiling light fixtures
• Caulk and adhesive residue: Smears on windows, tubs, and countertops that harden over time
• Painter's tape residue: Sticky film left on glass, hardware, and fixtures

The Pre-Move-In Deep Cleaning Process

Step 1: HVAC System First

This is the most important step and the one most people skip. Your HVAC system has been running during construction, pulling construction dust through every duct in the house:

• Replace all filters immediately — the builder's filters are loaded with construction dust
• Have ducts professionally cleaned if possible ($300-500 for a typical Jacksonville home)
• Vacuum all vent covers and registers with a HEPA vacuum
• Wipe inside each duct opening as far as you can reach
• Run the system on "fan only" for 30 minutes with windows open to flush remaining dust

Step 2: Top-Down Cleaning

Start at the ceiling and work your way down — always:

• Ceiling fans and light fixtures: Construction dust clings to fan blades and inside light fixtures. Remove globes and wash them. Wipe fan blades with a damp cloth — dry dusting just moves the fine particles around.
• Crown molding and top of doorframes: These are dust magnets that builders never touch
• Top of cabinets: In homes with kitchen cabinets that don't reach the ceiling, the tops collect thick layers of construction dust
• Walls: Wipe down all walls with a damp microfiber cloth. Drywall dust clings to walls electrostatically.

Step 3: Windows and Doors

New windows are always dirty from construction:

• Remove labels and stickers: Use Goo Gone or rubbing alcohol on adhesive residue
• Clean window tracks: Construction debris settles in tracks and prevents smooth operation. Vacuum first, then wipe with a damp cloth.
• Clean glass inside and out: Use a vinegar-water solution or commercial glass cleaner. Check for caulk smears on glass — remove with a plastic putty knife to avoid scratching.
• Wipe door hardware: Remove protective plastic film from hinges and knobs. Clean fingerprint smudges and adhesive residue.

Step 4: Kitchen Deep Clean

The kitchen requires the most detailed cleaning in a new home:

• Inside all cabinets: Vacuum first (drywall dust settles inside every cabinet), then wipe with a damp cloth. Check corners for construction debris.
• Cabinet exteriors: Remove any protective film. Wipe with a mild cleaner appropriate for the finish.
• Inside drawers: Vacuum and wipe. Builders leave sawdust, screws, and drywall dust in drawers routinely.
• Appliances: Run the dishwasher empty with vinegar. Wipe the inside of the refrigerator with baking soda solution. Clean the oven interior even if it's never been used — manufacturing oils need to be removed.
• Sink and faucet: Remove the aerator and flush the lines — construction debris in plumbing lines is common and will clog aerators
• Countertops: Clean and apply sealer if you have natural stone. Jacksonville's new builds often feature granite or quartz that needs initial cleaning.

Step 5: Bathrooms

• Clean inside vanity cabinets — drywall dust and construction debris are standard
• Remove labels from mirrors and fixtures
• Clean the tub and shower — remove protective film from fixtures and check for caulk smears
• Run water in all drains to flush construction debris
• Clean the bathroom toilet inside and out — yes, even new toilets need cleaning from construction dust

VOC Reduction: Making Your New Home Breathable

New homes in St. Augustine and Orange Park have the same VOC concerns as those in Jacksonville proper:

• Open windows whenever possible during the first 3 months — Florida's breezes help flush VOCs
• Run HVAC with fresh air intake to cycle indoor air
• Add houseplants known for air filtration: spider plants, peace lilies, and snake plants
• Avoid adding new chemical sources (harsh cleaners, air fresheners) while the home is still off-gassing
• Consider an air purifier with activated carbon for the master bedroom during the first 6 months
