Indoor Air Quality and Mold

Indoor air pollution, or “sick building syndrome,” has received a great deal of attention in recent years. LEW Environmental’s staff of industrial hygienists and environmental health science professionals determines what conditions could be contributing to mold, fungi growth and poor indoor air quality (IAQ). After assessing your structure, we make recommendations and take action to achieve good IAQ and protect the health of occupants and visitors.

The LEW Environmental team is skilled in using qualitative and quantitative techniques, and state-of-the-art equipment to identify the cause of stale air and disagreeable odors, along with eye, nose and throat irritation. Contributors may include:

  • Humidity, mold and mildew
  • Tobacco smoke
  • Excessive dust or allergens
  • Naturally occurring gases
  • Combustion gases
  • Pesticides
  • Fibrous dust
  • Heavy metal dust
  • Formaldehyde
  • Organic compounds

To determine the cause of poor indoor air quality, LEW Environmental uses investigative sampling, information & data collection, personnel & resident interviews, ventilation system inspections, and visual inspections. LEW Environmental air quality offerings also include treatment and remediation of fungi & mold growth, as well as thorough HVAC duct cleaning. 

Lead-Based Paint

Lead-based paint has become one of our country’s most highly regulated environmental issues. Because of its widespread use prior to 1978, lead-based paint may be found in residential, public, commercial, and industrial structures. LEW Environmental is one of the founding companies in the field of lead testing and remediation services, and is known throughout the U.S. as a pioneer and expert. Our team conducts environmental surveys for lead-based paint, as well as identifying associated lead-based paint hazards in dust, soil and water. We are also versed in writing lead abatement specifications, conducting lead abatement monitoring, and performing lead abatement activities.

LEW Environmental has performed thousands of lead inspections, site assessments and abatement projects. Using the most modern and proven procedures, we design environmentally effective, affordable solutions to meet client needs. With years of experience in the environmental lead field, LEW Environmental has become an industry teacher with established regulatory relationships and a vast knowledge of industry products. LEW Environmental conducts all of its environmental lead services in accordance with applicable city, state and federal regulations. All of our technicians are trained, licensed and experienced for each environmental concern they handle.


Millions of commercial, public and private structures include asbestos-containing materials. From the basement to the rooftop, it’s likely that asbestos could be present. This hazardous material can be found on furnaces and heating systems, door gaskets, pipe insulation, wall and ceiling materials, vinyl floor tiles, sheet flooring, patching compounds and textured paints, roofing shingles, sidings, appliances, and equipment located throughout your structure. Asbestos is not always easy to locate, and cannot be conclusively identified by the human eye.

LEW Environmental’s environmental professionals are trained in sampling and identifying potential asbestos-containing materials. Asbestos services include surveys, sampling, air monitoring, consulting and remediation. Our environmental professionals have the appropriate training, experience and necessary licenses to safely address asbestos issues. All samples collected by LEW Environmental are analyzed by an accredited laboratory, and handled under a strict quality control program to assure the safety of our clients and the integrity of our services. Whether it is two linear feet of asbestos pipe insulation or thousands of square feet of asbestos plaster and spray-on fireproofing, LEW Environmental assists clients with proper and safe identification, handling and disposal of asbestos-containing materials.
