Frequently Asked Questions


Lead Inspection

A lead risk assessment is a process used to determine the potential risks of lead exposure in a particular environment. It involves evaluating the presence of lead in various materials such as paint, water, soil, and other products. The assessment can be conducted in a variety of settings, such as homes, workplaces, and schools. The purpose of the assessment is to identify potential sources of lead exposure and to determine whether individuals in the environment are at risk of lead poisoning. Lead risk assessments typically involve an inspection of the environment, followed by laboratory analysis of samples taken from different areas. The results of the assessment can help determine the need for remediation or abatement measures to reduce or eliminate the risk of lead exposure. In general, lead risk assessments are conducted to protect the health and safety of individuals who may be exposed to lead in their environment, particularly children who are more susceptible to the harmful effects of lead exposure.

Preparing for a residential lead paint test involves taking several steps to ensure that the test is accurate and reliable. Here are some tips to prepare for a residential lead paint test:


  1. Identify the areas to be tested: Determine the areas in the home where you suspect lead paint may be present. This will help you identify the specific surfaces to be tested.
  2. Clear the areas to be tested: Clear the areas to be tested of any clutter or obstructions. This will ensure that the areas are easily accessible for the testing process.
  3. Follow the testing protocol: Follow the testing protocol as instructed by the testing professional. This may involve taking samples of paint chips or dust, or using an X-ray fluorescence (XRF) device to test for lead.
  4. Consider hiring a professional: Consider hiring a certified lead inspector or risk assessor to conduct the test. They will have the necessary equipment and expertise to perform the test accurately and safely.
    By taking these steps, you can help ensure that the residential lead paint test is accurate and reliable, and help protect the health and safety of those living in the home.

The main difference between a lead inspection and a risk assessment is their focus and purpose. A lead inspection is a surface-by-surface investigation to determine the presence of lead-based paint in a building. It is typically conducted using an X-ray fluorescence (XRF) analyzer or by collecting paint chip samples, which are then analyzed in a laboratory. The goal of a lead inspection is to identify the locations and extent of lead-based paint hazards in a building. On the other hand, a lead risk assessment is a comprehensive evaluation of potential lead hazards in a building, which includes identifying lead sources, assessing the likelihood of lead exposure, and evaluating the potential health effects of lead exposure. It involves an inspection of the environment and a review of the building’s history, including age, past renovations, and other factors that may contribute to lead exposure. The goal of a lead risk assessment is to develop a plan to control or eliminate lead hazards in the building and protect the health of occupants.


In summary, a lead inspection is a more focused and surface-level evaluation of the presence of lead-based paint, while a lead risk assessment is a more comprehensive and in-depth evaluation of potential lead hazards in a building, including sources of lead exposure and their potential health effects.

Asbestos Inspection

Testing for asbestos exposure in the air involves collecting samples of air and analyzing them for the presence of asbestos fibers. Here are some common methods used to test for asbestos exposure in the air:


Air sampling: Air samples are collected using a specialized pump that draws air through a filter designed to capture asbestos fibers. The sample is then analyzed under a microscope to determine the number and type of asbestos fibers present.

Transmission Electron Microscopy (TEM): TEM is a highly sensitive method for detecting asbestos fibers in air samples. This method involves using a powerful electron microscope to analyze the air sample and identify the type and size of asbestos fibers present.

Polarized Light Microscopy (PLM): PLM is a common method for analyzing air samples for asbestos fibers. The air sample is collected on a filter, which is then examined under a microscope that uses polarized light to identify the presence of asbestos fibers.
Phase Contrast Microscopy (PCM): PCM is another method for analyzing air samples for asbestos fibers. The air sample is collected on a filter and examined under a microscope that uses phase contrast to detect the presence of fibers.


It is important to note that testing for asbestos exposure in the air should only be performed by trained professionals using appropriate equipment and methods. Crown Environmental is certified as an asbestos testing firm for all issues related to asbestos exposure.

An asbestos survey is a comprehensive inspection and assessment of a building or structure to determine the presence, type, condition, and location of asbestos-containing materials (ACMs). The purpose of an asbestos survey is to identify potential asbestos hazards in a building, assess the risk of exposure, and develop a management plan to control or remove the asbestos safely.


The survey is typically conducted by a qualified asbestos consultant or surveyor who will visually inspect the building and collect samples of suspected ACMs for laboratory analysis. The survey may include the following steps:


Pre-Survey Assessment: The surveyor will review the building’s history and documentation to identify any potential asbestos-containing materials, including construction materials, insulation, flooring, and ceiling tiles.

Visual Inspection: The surveyor will conduct a visual inspection of the building, including all accessible areas, to identify potential ACMs.

Sample Collection: The surveyor will collect samples of suspected ACMs using a range of techniques, such as bulk sampling, air sampling, or dust sampling.

Laboratory Analysis: The collected samples are sent to an accredited laboratory for analysis to confirm the presence of asbestos fibers and determine the type and concentration of asbestos.


Report and management plan: The surveyor will prepare a detailed report of the survey findings and develop a management plan to control or remove the asbestos-containing materials safely, according to relevant regulations and guidelines.

Overall, an asbestos survey is an essential step in managing the risks associated with asbestos exposure and ensuring the safety of occupants and workers in a building.


Asbestos was commonly used in homes in New York and throughout the United States from the early 1900s through the 1970s. It was widely used in a variety of construction materials, including insulation, flooring, ceiling tiles, and pipe coverings, due to its durability, fire resistance, and insulating properties.


Asbestos-containing materials (ACMs) continued to be used in some construction products in the 1980s, although their use decreased significantly due to increased awareness of the health hazards associated with asbestos exposure. In 1989, the U.S. Environmental Protection Agency (EPA) issued a ban

on the manufacture, importation, processing, and distribution of most asbestos-containing products in the United States. However, the ban was

overturned by a federal court in 1991.


Today, the use of asbestos-containing materials is heavily regulated in the United States, and the handling, removal, and disposal of asbestos materials are subject to strict guidelines and regulations to protect the public and workers from exposure. If you are concerned about asbestos in your home in New York or anywhere else, it is advisable to contact a qualified asbestos professional to conduct an inspection and assessment.


Mold Inspection

If you suspect that your house has mold, there are several steps you can take to check for it:


Visual Inspection: Mold growth is often visible on surfaces, so start by visually inspecting your home for any signs of mold. Check for black or green spots on walls, ceilings, floors, and other surfaces. Look for any discoloration or staining and pay special attention to areas that are prone to moisture, such as bathrooms, kitchens, and basements.

Smell: Mold often has a musty odor, so use your nose to detect any unusual smells in your home.

Moisture Check: Mold thrives in moist environments, so check for any signs of water damage, leaks, or moisture problems in your home. Look for water stains on walls or ceilings, and check for any dampness in crawl spaces or basements.

Mold Testing: If you are unable to locate the mold, you may consider hiring a professional to conduct mold testing. There are different types of mold tests available, such as air sampling and surface testing. Air sampling involves collecting air samples and testing them for the presence of mold spores, while surface testing involves collecting samples from surfaces to determine the type and concentration of mold present.


If you find mold in your home, it is important to address the problem as soon as possible to prevent it from spreading and causing health problems. It is recommended to hire a qualified mold professional to test the areas safely and effectively.

Home mold tests can provide an indication of whether mold is present in your home, but their accuracy can vary depending on the type of test used and how it is conducted.


Some home mold tests are designed to detect the presence of mold spores in the air or on surfaces, while others are designed to identify specific types of mold. These tests typically involve taking samples of air or surface materials, which are then sent to a laboratory for analysis. However, there are several factors that can affect the accuracy of home mold tests. For example, mold spore levels can fluctuate depending on environmental conditions, such as temperature and humidity, which can affect the results of air sampling tests. Similarly, surface sampling tests may not always detect mold if the spores are not present on the surface at the time of testing.


In addition, home mold tests may not be able to identify the cause or extent of a mold problem, which can make it difficult to determine the best course of action for remediation.

Overall, while home mold tests can provide some useful information, it is often recommended to hire a qualified mold inspector to conduct a more comprehensive assessment of the mold problem in your home. Crown Environmental has the expertise and state-of-the-art equipment needed to identify the source and extent of the mold growth and develop an effective remediation plan.

Radon Testing

Radon is a naturally occurring radioactive gas that is found in the soil and rock. It is formed by the decay of uranium and can seep into homes and other buildings through cracks in the foundation, gaps around pipes, and other openings.


Radon can be found in all parts of the world, but certain areas are more prone to higher levels of radon. In the United States, radon is most commonly found in the Northeast, the Midwest, and the Rocky Mountain states. The U.S. Environmental Protection Agency (EPA) has designated high radon areas in the country based on the results of radon testing.


However, it is important to note that radon can be found in any building, regardless of its location or age. The only way to know if your home has high levels of radon is to conduct a radon test. The EPA recommends that all homes be tested for radon, and if high levels are found, steps should be taken to reduce the levels to protect the health of the occupants.

The amount of radon in a home can be influenced by several factors, including:


Soil Composition: The amount of uranium in the soil and rocks underneath a home can affect the level of radon that seeps into the structure.

Home Construction: The construction materials and methods used to build a home can affect the level of radon that enters the building. For example, airtight homes with limited ventilation may have higher levels of radon.

Weather Conditions: Changes in weather and atmospheric pressure can affect the amount of radon that enters a home.

Home Ventilation: The rate of air exchange in a home can affect the level of radon. Homes with poor ventilation or those that are tightly sealed may trap radon inside, leading to higher levels.


Radon is a colorless, odorless gas, and the only way to know if your home has high levels of radon is to conduct a radon test by a certified company such as Crown Environmental.


Radon gas can enter a home through any opening that allows air to flow between the inside and outside of the structure. However, certain areas of a home may be more prone to radon buildup than others.


The highest levels of radon are typically found in the basement or crawl space, especially if the foundation is made of porous materials such as concrete blocks or if there are cracks in the foundation. Radon gas can also accumulate in the lowest level of the home if there is limited ventilation or if the space is poorly sealed.

Other areas of the home that may have elevated radon levels include first-floor rooms that are in contact with the ground, such as a room built over a crawlspace or a room with a dirt floor. Radon can also seep into homes through gaps around pipes, walls, and floors.

Air Quality Testing

Poor air quality inside your home can cause a range of symptoms that can vary depending on the individual and the specific pollutants present. Some common symptoms of poor indoor air quality include:


  1. Irritation of the eyes, nose, and throat
  2. Headaches
  3. Fatigue and dizziness
  4. Respiratory problems, including coughing, wheezing, and shortness of breath
  5. Allergic reactions, such as sneezing, runny nose, and skin rashes
  6. Aggravation of asthma and other respiratory conditions
  7. Nausea and vomiting
  8. Difficulty concentrating and cognitive impairment
Long-term exposure to poor indoor air quality can also lead to more serious health problems, such as heart disease, lung cancer, and other chronic respiratory conditions.
If you experience these symptoms and suspect that poor indoor air quality may be the cause, it’s important to identify and address the source of the problem. Improving ventilation, reducing exposure to specific pollutants, and using air purification systems can help improve indoor air quality and alleviate symptoms.

Water Testing

There are several types of water testing that can be conducted to assess the quality of drinking water. Three common types of water testing are:


Microbiological Testing: This type of testing looks for the presence of bacteria, viruses, and other microorganisms in the water that can cause illness. Common tests include coliform bacteria testing, which looks for the presence of bacteria that indicate the possible presence of disease-causing organisms.

Chemical Testing: Chemical testing analyzes the water for the presence of various chemicals, including minerals, metals, pesticides, and industrial contaminants. Common tests include tests for lead, arsenic, nitrates, and volatile organic compounds (VOCs).

Physical Testing: Physical testing looks at the physical properties of the water, such as its pH level, turbidity, and temperature. These properties can affect the water’s taste, odor, and appearance, and can also impact its suitability for various uses.
