Safe Cleanup Checklist

🧱 Hidden Damage Inspection Checklist

Created by House Fire Solutions – Protecting Homeowners from Overlooked Fire Damage

Even after visible fire damage is cleared, hidden damage can silently threaten your home’s structure, air quality, and electrical systems.
This checklist helps you inspect beyond the surface — identifying issues that could cause long-term safety hazards or insurance underpayment.

🔥 1. Structural Damage

Goal: Identify weakened framing, foundation, and load-bearing elements affected by heat or water.

Inspection Area	What to Check	Why It’s Important
Framing & Joists	Look for char, cracks, warping, or smoke residue	Compromised strength even if only “smoke damaged”
Load-Bearing Walls	Inspect for hidden cracks under paint or drywall	Fire heat weakens integrity
Ceilings & Attic Joists	Probe wood for brittleness or soot stains	Indicates smoke or heat penetration
Foundation & Slab	Look for spalling, cracking, or heat discoloration	High heat can expand and fracture concrete
Subflooring	Remove sections to check for trapped moisture	Leads to rot and structural instability
Roof Trusses	Examine for hidden charring above ceiling drywall	Roofs often hide lingering damage

✅ Pro Tip: Hire a structural engineer for a post-fire load assessment before rebuilding.

⚡ 2. Electrical System Damage

Goal: Find melted insulation, short circuits, or hidden wiring hazards caused by heat and soot.

Inspection Area	What to Check	Why It’s Important
Main Electrical Panel	Look for soot, melted breakers, or corrosion	Hidden shorts can spark future fires
Wiring in Walls	Check insulation for brittleness or burn odor	Heat can damage copper without visible charring
Outlets & Switches	Replace any discolored or soot-stained plates	Smoke residue conducts electricity
Light Fixtures	Remove covers and check wiring and contacts	Hidden soot = potential arc points
Appliance Circuits	Test major lines (oven, washer, HVAC)	Ensure no voltage drop or resistance increase
Grounding & GFCIs	Verify all GFCIs reset and function properly	Common failure point after smoke exposure

✅ Pro Tip: Always have a licensed electrician test circuits with a megohmmeter post-fire.

💨 3. HVAC & Air Quality Systems

Goal: Detect smoke, soot, or moisture trapped in ducts and air handlers.

Inspection Area	What to Check	Why It’s Important
Ductwork (Supply & Return)	Inspect for soot, odor, and sticky residue	Circulates smoke particles throughout home
Air Handler / Furnace	Check blower motor and coil for black film	Can cause poor airflow and recontamination
Evaporator & Condenser Coils	Clean or replace after fire	Can cause poor airflow and recontamination
Air Filters	Replace immediately and after each cleaning cycle	Filters clog quickly with soot dust
Registers & Vents	Remove covers and clean interior duct openings	Hidden soot can smell for months
Odor Treatment	Ozone or hydroxyl deodorization	Restores clean air before move-in

✅ Pro Tip: Run an air quality test for VOCs and fine particulates before reoccupying your home.

💧 4. Plumbing & Water Systems

Goal: Find heat damage to pipes, joints, and fixtures from firefighting water or direct exposure.

Inspection Area	What to Check	Why It’s Important
PVC & PEX Pipes	Look for discoloration or softness	Heat causes future burst risk
Copper Pipes	Inspect for warping or pinholes	Heat weakens solder joints
Fixtures (Sinks, Tubs)	Check seals and caulk for melting	May leak later
Sewer Lines	Camera inspect under slab or crawlspace	Debris or soot can block flow
Hot Water Heater	Examine pressure relief valve and tank	Can rupture from heat stress

✅ Pro Tip: Have a licensed plumber pressure-test your system post-fire before turning on main water.

🪵 5. Insulation, Drywall & Hidden Cavities

Goal: Identify smoke and moisture trapped behind walls.

Inspection Area	What to Check	Why It’s Important
Wall Cavities	Cut test holes to check for odor and soot	Soot-laden insulation causes smell reoccurrence
Attic Insulation	Inspect for dark residue or compressed fibers	Retains odor and toxins
Drywall	Smell test and infrared scan for moisture	Mold forms within 72 hours of water exposure
Ceiling Cavities	Check under insulation layers for soot	Mold forms within 72 hours of water exposure
Behind Cabinets	Remove baseboard and toe-kicks	Hidden damage and odors linger

✅ Pro Tip: Replace all insulation exposed to smoke or moisture — cleaning won’t fix trapped odor molecules.

🧯 6. Smoke, Odor & Air Contamination

Goal: Ensure full deodorization and air quality restoration.

Inspection Area	What to Check	Why It’s Important
Porous Surfaces (Wood, Fabric)	Test for lingering odor	Absorbed smoke = long-term smell
Walls & Ceilings	UV or ozone fog test for invisible residue	Soot film reappears with humidity
HVAC Returns	Smell test after 24 hours of operation	Reveals trapped odor source
Crawlspaces / Attic	Smell test after 24 hours of operation	Spreads airborne contaminants
Air Test Results	Fine particulate levels >35 µg/m³ = unsafe	Guides final cleaning steps

✅ Pro Tip: Always perform a post-cleaning air quality test to verify safety before re-entry.

🧰 7. Contents & Personal Property

Goal: Identify household items that can or can’t be restored safely.

Inspection Area	What to Check	Why It’s Important
Furniture	Check for odor absorption and soot film	Check for odor absorption and soot film
Electronics	Test for residue and corrosion	Smoke particles short-circuit boards
Clothing & Fabrics	Smell test and UV check	Smell test and UV check
Artwork & Documents	Smoke embeds deeply in fibers	Heat can cause permanent discoloration
Mattresses & Upholstery	Always replace	Fire and smoke toxins can’t be cleaned

✅ Pro Tip: Document all unsalvageable contents with photos and receipts for insurance reimbursement.

🧩 8. Miscellaneous & Hidden Systems

Inspection Area	What to Check	Why It’s Important
Attic Wiring / Fans	Inspect for melted sheathing	Common hidden hazard
Crawlspace Insulation	Test for odor and residue	Airborne soot collects in low areas
Chimney / Flue	Clean and camera inspect	May have soot blockage or cracks
Garage / Workshop	Inspect for chemical residue	Risk of fume ignition
Solar Panels / Wiring	Check inverters for corrosion	Heat damage can void warranties

✅ Pro Tip: Include these in your insurance supplement if overlooked in the original adjuster report.
