Fire & Smoke Damage Assessment and Soot Testing in San Diego

After a fire, the visible damage is only part of the problem. Smoke, soot, and combustion byproducts can spread throughout a structure — well beyond the area of direct flame contact — contaminating surfaces, HVAC systems, and indoor air. XRF Research provides comprehensive fire and smoke damage assessments to document contamination, support insurance claims, and guide remediation efforts for residential and commercial properties.

Why Professional Fire Damage Assessment is Important

Fire generates a complex mixture of hazardous substances depending on what materials burned. Combustion of synthetic materials (plastics, foam, treated wood, electronics, vinyl flooring) can produce toxic compounds including polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), hydrogen chloride, hydrogen cyanide, and in some cases dioxins and furans. Soot particles carry these contaminants throughout the structure via air currents and HVAC systems.

Our Fire & Smoke Damage Assessment Services

Soot and Char Analysis

• Surface wipe sampling for soot deposition on walls, ceilings, and contents
• Quantitative analysis for combustion residue (chloride, corrosivity, metals)
• Visual documentation of char patterns, smoke deposition, and damage extent
• Comparison of contaminated areas to unaffected reference areas

Air Quality Testing

• VOC canister sampling to assess airborne chemical contamination from combustion
• Particulate monitoring (PM2.5 and PM10) for residual smoke particles
• Formaldehyde and aldehyde sampling where engineered wood products were involved
• Odor assessment and source identification

Specialized Analysis

• Dioxin and furan screening for fires involving PVC, treated wood, or chlorinated materials
• Heavy metals analysis in ash and soot residue
• Asbestos assessment when fire has damaged suspect building materials in pre-1980 structures
• Lead paint disturbance assessment when fire or fire suppression has disturbed painted surfaces in pre-1978 buildings

Pre- and Post-Remediation Testing

• Pre-remediation baseline sampling to establish contamination levels and guide cleanup scope
• Post-remediation clearance testing to verify successful decontamination
• Independent third-party documentation for insurance and regulatory compliance
