Fire Damage Restoration in Caldwell.

If smoke entered the HVAC system, the system needs to be cleaned per NADCA (National Air Duct Cleaners Association) standards before re-occupancy. Soot inside ductwork acts as an odor reservoir — every time the HVAC runs, it pushes that residue back into the living space. Owners report "the smoke smell came back" weeks after restoration. The reason is almost always that the ducts were not properly cleaned.

Our HVAC scope: source removal (HEPA vacuuming of supply + return ducts), antimicrobial treatment, replacement of any porous duct insulation that was contaminated, and replacement of the air handler filter + any disposable components. We document with before/after photos at multiple inspection points so the carrier sees the work was actually completed and not just billed.

For homes with old ductwork that was already in marginal condition before the fire, we will tell you honestly when replacement makes more sense than cleaning. The decision drives a different scope, different timeline, different insurance discussion — better to know on day one than discover after a partial cleaning that the system needs replacement anyway.

The fire department's job is to put the fire out. They do it well. What they leave behind is the start of the restoration job — and the damage that determines the eventual claim size has very little to do with the visible burn area.

Soot is acidic and moves on air currents. While the fire was burning, the HVAC system likely circulated soot-laden air through every room of the structure. Soot settled on horizontal surfaces, infiltrated upholstery and carpet fibers, and coated the inside of ductwork. Heat caused volatile organic compounds in plastics, fabrics, and finishes to off-gas, and those compounds redeposited on cooler surfaces as a sticky odor-bearing residue that does not wash off.

Our scope addresses each: HEPA vacuuming of horizontal surfaces, dry-chem sponge cleaning of walls and ceilings, HVAC duct cleaning per NADCA standards, content pack-out for items that need shop-cleaning, and hydroxyl or ozone treatment for porous materials in the affected envelope. None of this is optional — skipping any phase leaves residual odor that returns within weeks.
