Visual inspection of accessible areas of the residence to identify and document building materials suspected of containing asbestos. Common non-suspect materials such as wood, glass, metal, carpet, and fiberglass are generally excluded. Includes collection of one representative bulk sample for accredited laboratory asbestos analysis. Additional samples may be collected when recommended for an additional fee.

Collection of a representative bulk sample from a specific building material of concern or prior to renovation, repair, or removal. Common materials include popcorn ceiling texture, vinyl or linoleum flooring, floor tile and mastic, attic insulation, and furnace or duct insulation. The sample is submitted to an accredited laboratory for asbestos analysis.

Asbestos inspection and bulk sampling performed prior to renovation or demolition to help satisfy applicable Bay Area Air District and Cal/OSHA requirements. Building materials that may be disturbed are identified, documented, and sampled as needed, including drywall, plaster, popcorn ceiling texture, flooring, mastic, insulation, roofing, stucco, siding, and other suspect materials.

Air sampling performed to evaluate airborne asbestos fibers following suspected disturbance, damage, renovation, or removal of asbestos-containing or suspect materials. Samples are collected using specialized air-sampling equipment and submitted to an accredited laboratory for Transmission Electron Microscopy (TEM) analysis to determine whether asbestos fibers are present in the sampled air.

Post-abatement clearance inspection performed following asbestos removal. Includes a detailed visual inspection of the work area and containment for visible dust, debris, or residual material. After a satisfactory visual inspection, air samples are collected and submitted for TEM analysis prior to containment removal, re-occupancy, or reconstruction.

Inspection and testing of interior and exterior painted surfaces to evaluate the presence of lead. Representative paint-chip samples are collected from selected building components and submitted to an accredited laboratory for analysis. Commonly performed before renovation, repair, demolition, or repainting, particularly in pre-1978 buildings.

Assessment performed to identify potential lead hazards in and around a property, particularly where children or other occupants may be at increased risk of exposure. Depending on site conditions and areas of concern, testing may include painted surfaces, interior dust, exterior soil, and drinking water. Laboratory results are evaluated against applicable standards and guidance to determine whether elevated lead levels or potential exposure hazards are present.

Lead-based paint testing for contractors, property owners, and others planning renovation, repair, or painting activities in pre-1978 housing or child-occupied facilities. Representative paint-chip samples are collected from painted components that may be disturbed and submitted for laboratory analysis. Testing can help determine whether EPA RRP lead-safe work practices apply rather than automatically assuming lead-based paint is present.

Comprehensive mold and moisture inspection of accessible living areas and, when accessible, attic and crawl-space areas. The inspection includes visual evaluation, moisture-meter testing, and thermal imaging to help identify visible mold growth, leaks, water intrusion, and moisture-prone conditions. Mold air sampling is also performed to evaluate airborne spore levels and identify elevated or unusual mold conditions.

Air sampling performed to evaluate airborne mold spore levels and identify elevated or unusual indoor conditions. Testing includes indoor air samples and one outdoor reference sample for comparison with naturally occurring background levels. Laboratory analysis identifies the types and concentrations of mold spores detected in each sample.

Post-remediation clearance inspection performed after mold removal or remediation. Includes a detailed visual evaluation of the affected work areas to verify that visible mold growth, debris, and impacted materials have been properly removed, cleaned, or treated. Air samples are then collected from the work area or containment to evaluate airborne mold spore levels before containment removal, reconstruction, or re-occupancy.

Indoor air sampling performed to evaluate two common indoor air quality concerns: volatile organic compounds (VOCs) and airborne mold spores. VOC testing can help identify chemicals emitted from building materials, furnishings, coatings, adhesives, cleaners, and other indoor sources. Mold air sampling identifies the types and concentrations of airborne spores present and helps evaluate whether unusual indoor conditions exist.

Radon testing performed to evaluate whether elevated radon gas levels are present in a home or building. ERT places two passive radon test canisters for approximately 3  days, then retrieves and submits them to an accredited laboratory for analysis. A continuous radon monitor is also operated onsite to provide supplemental real-time readings throughout the testing period.

Formaldehyde air testing performed to evaluate indoor concentrations associated with building materials, manufactured wood products, cabinetry, flooring, furnishings, coatings, household products, smoke, and combustion sources. Especially useful in newly constructed or recently renovated homes. Includes one 30-minute indoor air sample submitted to an accredited laboratory, plus real-time room-to-room formaldehyde screening onsite.

Indoor air testing performed to evaluate fine particulate matter (PM2.5) levels. A direct-reading handheld meter is used to obtain real-time measurements throughout selected areas of the home or building. Commonly requested following construction, renovation, demolition, wildfire smoke, nearby outdoor work, or other conditions that may have affected indoor air quality.

Indoor air testing performed to evaluate carbon dioxide (CO₂) levels and ventilation conditions. Indoor CO₂ is influenced primarily by occupant respiration and the amount of outdoor air supplied to a space. A direct-reading meter is used to obtain real-time measurements throughout selected areas and help identify rooms with inadequate ventilation or elevated occupant-related CO₂ levels.

Indoor air testing performed to evaluate carbon monoxide (CO), a colorless and odorless gas produced by incomplete combustion. Potential sources include furnaces, water heaters, fireplaces, gas appliances, generators, and vehicle exhaust. A direct-reading meter is used to obtain real-time CO measurements throughout selected areas of the home or building.

Onsite testing performed to measure electric and magnetic field (EMF) levels within a home or building. Common sources include electrical wiring, service panels, appliances, computers, transformers, and nearby power lines. Direct-reading instruments are used to obtain real-time measurements throughout selected areas and identify locations with comparatively elevated electric or magnetic field readings.

Assessment of settled dust following construction, renovation, cutting, grinding, or demolition activities involving concrete, masonry, tile, stone, or similar materials. ERT can collect representative dust samples for laboratory silica analysis to evaluate whether residual silica-containing dust is present. Especially useful when work was performed without adequate containment, dust suppression, or air filtration and contamination is suspected.

ERT provides targeted soil sampling and laboratory testing when there is a specific concern that soil at a property may have been impacted by contamination. This service may be appropriate following a structure fire, demolition, spill, past property use, buried debris, imported fill material, construction activity, or other condition that raises concern about contaminants in surface or subsurface soil.
