Post-Construction Duct Cleaning
in Lewisville TX
Your new Castle Hills home is beautiful. And inside your brand-new duct system, there is drywall dust, fiberglass strands, sawdust, and joint compound that went in during the build and has been sitting there since the day the HVAC was test-run — while workers were still sanding drywall. Builders don’t clean ducts before handover. We do.
Why Every New Lewisville Home Has Dirty Ducts
This is not a worst-case scenario. This is standard. Every new construction home in Lewisville has construction debris in its duct system — regardless of the builder and regardless of the price point.
What Goes Into the Ducts During Construction
- Fine drywall dust — gypsum particles that coat duct interior walls throughout the trunk lines. The finest particles, deepest penetration.
- Fiberglass insulation strands — from attic and wall installation, migrating into supply ducts through gaps at air handler connections.
- Sawdust and wood debris — from framing and trim work, settling at trunk line low points and direction changes.
- Joint compound particles — from drywall finishing and sanding, found at return air plenums and return duct near the air handler.
- Construction tape and foam debris — small pieces from duct connections made during the build.

When to Schedule
The right window is within 60–90 days of move-in. Here’s why timing matters.
Pre-Close (Best)
If you have access to the home before taking possession, pre-close cleaning is the cleanest option — construction debris is extracted before you’ve ever used the system. Available for new builds with builder cooperation or pre-handover access.
60–90 Days After Move-In (Ideal)
Enough time to confirm the home is fully complete and identify any initial HVAC issues — but soon enough that you haven’t been running the system through months of debris circulation. This is the window we recommend for most Northpointe buyers.
Don’t Wait a Full Season
Construction debris in new ducts doesn’t produce the visible dust puffs that older homes develop — the particles are too fine. The first indication most homeowners get is unexplained allergy symptoms. By then they’ve been breathing it for months.
Post-Construction Cleaning Cost
Most new Castle Hills Northpointe builds are 2,000–3,500 sq ft with one or two HVAC systems.
What Castle Hills Northpointe Homeowners Say
“Moved into our Toll Brothers home in Northpointe in February. Scheduled cleaning at 45 days. The before photos showed white drywall dust coating throughout the trunk line. We had been running the system for six weeks before we knew.”
“Our builder did a punch list clean-out before closing. We assumed that meant the ducts were clean. It did not. They extracted what looked like a small bucket of construction material from our 90-day-old home.”
