Indoor Smell Issue Investigation
Smell issue investigation is a systematic approach to identifying and resolving odor complaints in indoor environments. Our comprehensive methodology combines advanced air quality testing, HVAC assessments, and microbiological analysis to pinpoint odor sources and provide effective mitigation strategies. Using our proven 6-phase protocol, we ensure persistent odors are eliminated, not just masked.
Smell issue investigation is a specialized service designed to identify and resolve persistent odor problems in residential and commercial properties. Unlike basic air freshening or temporary masking solutions, this comprehensive assessment addresses the root causes of unwanted odors through systematic evaluation and targeted remediation. Persistent odors often indicate underlying indoor air quality issues, plumbing problems, or HVAC system contamination that can impact health and comfort if left unaddressed.
Why Investigate Smell Issues?
Phase 1 – Baseline Indoor Air Quality Assessment
- VOCs measurement (threshold: >500 ppb indicates high concern)
- Formaldehyde testing (threshold: >0.1 ppm requires attention)
- Particulate matter analysis (PM2.5/PM10)
- CO₂ levels (threshold: >1000 ppm indicates ventilation issues)
- Relative humidity monitoring (threshold: >60% creates mold risk)
Laboratory Analysis
Phase 2 – HVAC/Ventilation & Circulation Inspection
- Comprehensive evaluation of HVAC coils, ducts, and drainage systems
- Fresh air supply and exhaust system verification
- Pressure balance and infiltration/exfiltration assessment
- Performance benchmarking against space requirements
Phase 3 – Plumbing & Drainage System Assessment
- Drain trap inspection and functionality testing
- Storm drainage and plumbing leak detection
- Advanced diagnostic tools including endoscopy and thermography
- Septic system and wastewater infrastructure mapping
Result Interpretation
Phase 4 – Targeted Odor & Microbiological Investigation
- Airborne microbial sampling using culture and qPCR methods
- Specialized testing for MVOCs (Microbial Volatile Organic Compounds)
- Sulfur compounds and ammonia detection
- Surface contamination analysis for bacteria and fecal indicators
Phase 5 – Surface, Moisture & Source Tracking
- HVAC system biofilm and mold contamination assessment
- Infrared moisture mapping to identify hidden water issues
- Grease trap and drainage system detailed inspections
Developing a Mitigation Plan
Risk & Source Likelihood Matrix Evaluation
Our systematic approach rates each potential odor source by probability, impact severity, and required urgency(Smell Issue Investigation Matrix). This ensures resources are focused on the most critical issues first, with clear timelines for remediation.
Root Cause Analysis
- Confidence scoring in source identification (0-100%)
- Contributing factors analysis
- Remediation feasibility assessment (Easy/Moderate/Difficult)
Verification Protocol
Post-remediation testing within 7-14 days to ensure effectiveness, with follow-up OIS surveys requiring minimum 2-point improvement scores.
How is it Performed?
Our investigation report is designed to thoroughly identify and explain the root cause of persistent odors in residential or commercial spaces. Every report utilizes our advanced testing protocols, documenting measurable data such as VOC levels, humidity, HVAC system findings, microbial analysis, and Odor Impact Scale scores. This evidence-based approach analyzes each potential odor source using a Risk & Source Likelihood Matrix, scoring every candidate by probability, severity, and urgency. The report quantifies how confident we are in pinpointing the source, outlines all contributing factors, and explains the feasibility of each remediation option, ensuring clients understand both the science and the logic behind our conclusions.
Beyond identifying the problem, our report provides clear, step-by-step remediation guidance. Recommendations are ranked based on priority, with actions ranging from routine maintenance to urgent interventions. Clients receive tailored instructions for immediate solutions and long-term monitoring, including post-remediation sampling and follow-up OIS reassessment to verify improvement. Our expert team supports clients throughout the entire process, answering questions and adjusting the plan as needed until the odor issue is resolved to satisfaction. The goal is not just to report findings, but to deliver actionable solutions and ongoing support for a healthier indoor environment.
