Why Post-Construction Duct Cleaning is Essential
Renovation and construction create enormous amounts of fine dust that infiltrates every space in your home—including your ductwork. Drywall dust, wood sawdust, joint compound particles, and insulation fibers settle throughout duct systems through uncovered vents and return grilles that contractors often leave exposed during construction.
When your HVAC system first runs after construction, it distributes this dust throughout your entire home, settling on furniture, countertops, and worst of all—entering your lungs. Professional post-construction duct cleaning removes this debris before occupancy, ensuring healthy air quality from day one.
Construction Debris Found in Ductwork
Typical renovations introduce multiple contaminant types into duct systems:
- Drywall Dust: Ultra-fine gypsum particles from cutting, sanding, and finishing. Creates powdery white coating throughout ductwork. Most common and problematic construction contaminant
- Joint Compound: Sanding creates massive amounts of fine dust that easily becomes airborne and infiltrates ducts through any opening
- Wood Sawdust: Cutting lumber creates particles ranging from large chips to fine dust. Accumulates in duct bends and low points
- Insulation Fibers: Fiberglass and mineral wool particles become airborne during installation. Irritate skin, eyes, and respiratory system
- Paint Overspray: Spray painting creates airborne droplets that dry into particles throughout ductwork
- Concrete/Tile Dust: Cutting concrete, tile, or stone creates silica-containing dust extremely harmful to lungs
- Metal Shavings: Cutting metal ducts, vents, or fixtures creates sharp particles throughout system
- Packaging Materials: Cardboard dust, plastic particles, and foam fragments from material packaging
Health Risks of Construction Dust
Construction debris in ductwork creates serious health concerns:
- Respiratory Irritation: Fine particles irritate airways causing coughing, wheezing, and difficulty breathing, especially for children and elderly
- Allergic Reactions: Many construction materials trigger allergic responses including rashes, itchy eyes, and respiratory distress
- Asthma Triggers: Construction dust significantly worsens asthma symptoms, potentially causing serious attacks requiring emergency treatment
- Silica Exposure: Dust from concrete, tile, and stone cutting contains crystalline silica linked to serious lung disease with long-term exposure
- Chemical Exposure: Paint particles, adhesive vapors, and treatment chemicals circulate through contaminated ductwork
- Persistent Contamination: Without professional cleaning, construction dust continues circulating for months or years affecting long-term health
Our Post-Construction Cleaning Process
Pre-Cleaning Inspection
Assess contamination extent, photograph debris levels, identify all affected areas requiring attention.
System Protection
Protect HVAC equipment and home surfaces. Set up containment preventing dust spread during cleaning.
HEPA Vacuum Setup
Connect truck-mounted HEPA filtration system. Creates negative pressure pulling all debris into containment.
Aggressive Agitation
Use rotating brushes and compressed air dislodging all stuck-on construction debris from duct surfaces.
Complete Extraction
Powerful vacuum removes all loosened debris. HEPA filters capture 99.97% of particles preventing re-contamination.
Component Cleaning
Clean air handler, blower assembly, coils, and registers removing all construction dust from HVAC components.
Optimal Timing for Post-Construction Cleaning
Scheduling makes a huge difference in cleaning effectiveness:
- After Drywall Finishing: Wait until all sanding, texturing, and painting complete. This is single biggest dust generator
- Before Final Cleaning: Schedule duct cleaning before final house cleaning. Otherwise construction dust re-contaminates cleaned surfaces
- Before Moving In: Complete before furniture and belongings arrive. Prevents dust from settling on your possessions
- After Contractor Exit: Wait until all construction work finished and contractors have left to avoid re-contamination
- Coordinate with Builder Cleaning: For new construction, schedule with final builder cleaning for complete home preparation
Post-Construction Cleaning Pricing
Pricing based on home size and renovation scope:
- Small Renovation (1-2 rooms): $400-$550 - Kitchen, bathroom, or bedroom remodels with moderate dust generation
- Standard Renovation (Multiple rooms): $550-$700 - Whole-floor renovations or multiple room remodels
- Large Renovation (Whole house): $700-$1,000 - Complete home remodels with extensive drywall work and dust generation
- New Construction: See New Home Cleaning for builder debris removal pricing
What's Included: Complete duct system cleaning, HEPA filtration, before/after photos, verification inspection, and safe occupancy certification.
Protecting Ducts During Construction
Prevention reduces but doesn't eliminate the need for professional cleaning:
- Cover All Vents: Tape plastic over all supply vents and return grilles during construction. Not foolproof but reduces infiltration
- Seal Returns: Return vents are primary entry points for construction dust. Extra sealing attention essential
- Keep HVAC Off: Don't run heating or cooling during construction. Creates negative pressure pulling dust into ductwork
- Seal Air Handler: Cover air handler and filter slot preventing dust from entering HVAC equipment
- Professional Cleaning Still Required: Even with best protection, professional post-construction cleaning remains essential

Frequently Asked Questions
How much does post-construction duct cleaning cost?
Post-construction duct cleaning costs $400-$800 depending on home size and construction scope. Standard renovations average $500-$650. Whole-house remodels cost $700-$1,000. Price includes complete debris removal, HEPA filtration, before/after documentation, and verification cleaning ensuring all construction dust is eliminated from ductwork.
When should I clean ducts after construction?
Clean ducts after construction completion but before final occupancy. Ideal timing is after all drywall finishing and painting but before moving furniture back. This prevents construction dust from circulating when HVAC first runs. Wait until all sanding, cutting, and dust-generating work is completely finished to avoid re-contamination.
What construction debris gets in ductwork?
Construction creates massive amounts of fine dust: drywall particles, wood sawdust, insulation fibers, joint compound dust, paint overspray, metal shavings, concrete dust, and packaging materials. Average renovation generates 30-50 pounds of debris that infiltrates ductwork through uncovered vents and return grilles. Without professional cleaning, this circulates throughout home for months.
