Indoor Air Quality Testing

VOC testing: science-based chemical air quality investigation

Persistent odors, unexplained symptoms, or recent renovations? ESG uses accredited laboratory analysis to identify chemical compounds in your indoor air and, combined with building history and field observations, help narrow down their likely sources. We test. We never sell remediation.

From unexplained odors to chemical identification

VOCs are invisible and cannot be identified by smell alone, and there is no universal odor test. Laboratory sampling can identify certain compounds captured in a collected sample. Combined with building history, odor patterns, field observations, and screening data, it may help narrow potential sources. A sample alone usually does not prove the source or describe the entire building.

Before Testing

Chemical odors, no identified source

Occupants notice persistent smells or experience symptoms like headaches, dizziness, or respiratory irritation. Without testing, there is no way to know which compounds are present or at what levels.

After ESG Testing

Compounds identified, likely sources narrowed

A written report identifies the chemical compounds detected in the samples, their concentrations, likely sources, and clear recommendations, giving building owners and occupants actionable information.

A complete VOC investigation, not just a sample

ESG's VOC assessments combine building history review, environmental measurements, specialized air sampling, and accredited laboratory analysis to identify what chemicals are present and help narrow down where they may be coming from.

Why ESG

Independent testing: no products to sell, no remediation work

Environmental Solutions Group has been performing independent environmental testing and consulting since 2002, more than 23 years. Our VOC assessments are driven by science and building investigation, not by a sales agenda for air purifiers, filters, or treatment products.

Because we never sell remediation services or air quality products, our recommendations are genuinely independent. If elevated VOCs are identified, we tell you what the likely source is and what practical steps can address it, without any upsell.

ESG's team includes a Council-certified Indoor Environmental Consultant (CIEC), a Council-certified Indoor Air Quality Manager (CIAQM), Council-certified Residential Indoor Environmentalists (CRIEs), and staff certified in BPI Infiltration and Duct Leakage testing, with the training and equipment to investigate chemical air quality concerns in homes, offices, schools, healthcare facilities, and industrial settings.

How VOC testing works

A structured four-step investigation that moves from your initial concern to lab-verified chemical identification and clear guidance.

Lab analysis

Samples are analyzed by accredited environmental laboratories, identifying the individual VOC compounds captured in the sample, their concentrations, and total VOC levels: data that cannot be obtained through odor alone.

Clear report

You receive a detailed written report with lab findings, source analysis, and practical recommendations. An ESG professional is available to review every result with you.

Professional testing vs. guesswork

ESG VOC testing: laboratory-verified

Professional VOC testing identifies the chemical compounds captured in your air samples and their concentrations. Combined with building observations, that data helps narrow the likely sources and gives you something objective to work from.

  • Identifies specific VOC compounds, not just "chemical odor"
  • Traces compounds to likely source categories (cleaning products, building materials, HVAC, etc.)
  • Provides independent recommendations with no products to sell
  • Documented laboratory data for workplace complaints, insurance, or legal matters

Consumer monitors & air "purifiers": their limits

Consumer air quality monitors and air purifiers do not identify which specific compounds are present, cannot trace contamination to a source, and may mask problems rather than solve them.

  • Report only generic "VOC" readings with no compound identification
  • Cannot determine whether compounds originate from normal use or contamination
  • Do not provide documentation for workplace or legal purposes
  • Treating symptoms without identifying the source leaves the problem unresolved

Independent answers you can rely on

No fabricated promises, just the facts about how we work.

VOC testing: frequently asked questions

What are VOCs and why do they matter indoors?

Volatile Organic Compounds (VOCs) are carbon-based chemicals that easily evaporate into the air at room temperature. Because buildings trap air, VOCs from cleaning products, building materials, furnishings, paints, and solvents can accumulate to concentrations that cause noticeable odors or, at higher levels, occupant symptoms such as headaches, dizziness, or respiratory irritation. ESG evaluates and documents environmental conditions. ESG does not diagnose medical conditions or determine whether a building condition caused symptoms. Results may be shared with a qualified healthcare provider.

What are common signs that I may need VOC testing?

The most common triggers are persistent chemical or solvent-like odors that cannot be traced to an obvious source, occupant symptoms that improve when people leave the building and return when they re-enter, recent renovations or new material installations (flooring, paint, cabinets), and indoor air quality complaints in offices, schools, or healthcare facilities.

Can VOC testing identify where the chemicals are coming from?

Lab analysis identifies which specific chemical compounds are present. By combining that data with the building walkthrough, occupant interview, and environmental measurements, ESG can often narrow down the likely source category, whether that is cleaning products, off-gassing building materials, HVAC contamination, stored chemicals, or an external industrial source.

Is VOC testing the same as measuring air quality with a consumer monitor?

No. Consumer monitors report a generic "total VOC" number that cannot identify which compounds are present or at what levels. Accredited laboratory analysis identifies individual chemical compounds with precision. This approach provides scientifically defensible data for source investigation, workplace complaints, insurance, or legal purposes.

Do new buildings or renovations need VOC testing?

New construction and recent renovations are a common reason for VOC testing. Many building materials, including flooring adhesives, paints, sealants, cabinetry, and furniture, release VOCs during installation and curing. Testing can confirm whether materials are affecting air quality and inform ventilation strategies or occupancy timing decisions.

Does ESG sell air purifiers or remediation products after testing?

No. ESG is an independent testing and consulting firm only. We do not sell air purifiers, filters, or any treatment products. Our recommendations are entirely science-driven and focused on identifying and removing the source of contamination (improving ventilation, adjusting cleaning practices, or isolating chemical sources), not on selling equipment.
