Duct Mold Removal Service in Alexandria, VA
Duct mold removal addresses visible mold growth on the interior surfaces of your HVAC ductwork — not just the smell, but the actual colonies. Mold inside ducts distributes spores to every room the system serves, so it's not a localized problem once it's established. We physically remove mold-contaminated material where possible, treat remaining surfaces, and help you identify the moisture source that allowed growth in the first place. Without fixing the moisture problem, mold will return regardless of what's applied to the duct walls.

How It Works
Our Process for Duct Mold Removal Service
- 1
Mold Assessment
We inspect accessible duct sections with lighting and a camera to map where mold growth is present and how far it extends through the system.
- 2
Containment
Affected registers are sealed off from living areas before any disturbance begins, preventing spore release into rooms during removal work.
- 3
Physical Removal and Surface Treatment
Mold is mechanically removed from duct surfaces, then an EPA-registered encapsulant or biocide is applied to treated areas to inhibit regrowth.
- 4
Moisture Source Discussion
We walk you through what we found — condensation issues, leaking duct joints, or undersized return systems — so you can address the root cause.
Alexandria Context
Why this matters in Alexandria
Alexandria's mix of older slab-on-grade homes and basement crawlspace construction creates chronic moisture entry points. Duct systems in these homes run through unconditioned spaces where condensation forms on cold metal in summer and feeds mold year after year.
Straight Talk
About pricing & scope
Scope depends on how extensive the mold growth is and whether it's limited to accessible surfaces or has penetrated duct lining material that may need replacement. Fiberglass duct liner with deep mold growth cannot be cleaned — it needs to come out.
