Thank you for inquiring about NAL East Environmental Services (National Analytical Laboratories) for your indoor air quality evaluation. This information pertains to clients purchasing a property and/or just recently purchased a property and want to determine if there are any environmental issues inside this property. This indoor air quality inspection for a buyer and/or someone who has recently purchased a property includes a complete visual inspection of the entire property including the attic, crawlspace, garage, and every room, cabinet and closet in the property including the HVAC system and the exterior. A Moisture meter can be used on the walls, ceilings and floors to determine if any moisture is hidden inside those areas. Pictures are taken and you will get a copy of those pictures with your microbial results report.

NAL East will include three (3) samples, two (2) of which are air samples using high volume air pumps to determine what is present inside the property and at what levels. Our sample results will tell us if the levels and kinds of molds present inside the property are considered acceptable, low, slightly elevated or extremely elevated. In addition, our sample results will report the levels of background debris, fibrous particulates, hyphal fragments, insect fragments and skin cell fragments. The samples are submitted to EMSL Analytical, a fully accredited nationwide Laboratory. One outdoor air sample establishes a baseline for the comparative evaluation of the indoor samples. 

Since you are purchasing and/or purchased a property, probably the biggest investment of your life, it is extremely important to know the air quality levels inside the property. When mold grows, it is usually behind walls, under floors, above ceiling tiles or behind shower walls. Mold and fungal growth can cause deterioration of building materials and lead to structural compromise. The state of California mandates mold testing before you can by a property. Other states plan to follow this procedure in the near future as part of the disclosure plan. If the seller didn’t disclose that there was a mold issue and we determine that there is, the seller is responsible.

Within 12 to 24 hours after the inspection is completed you will receive a comprehensive report of the Environmental Consultants’ findings during the inspection, as well as an analytical report written by the microbiology lab stating what kinds of molds are present and at what levels and they will rate the levels and kinds of molds that were detected to tell us if there are any airborne concerns inside the property. 

We will inspect to see if there are any issues that may have been an issue before you buy the property. In addition, our inspectors are trained, certified inspectors and usually see things that other people don’t see. If you are the buyer, an inspection by a Certified Indoor Environmentalist will tell you if there are any hidden issues. 

Usually, the issues are minor and, in most instances, can be an easy fix, but you certainly want to know if there is anything there not seen by the home inspector. We inspect the property with your best interest in mind.

Keep in mind that every property has mold, it’s just a question of what kinds and how much. The microbiologist will tell us if the levels found in your property are considered safe, slightly elevated and extremely elevated.

Again, pictures are taken and we will mail you a copy of the pictures with your microbial results report. Based on your visual inspection and sample results, our Certified Mold Remediator Supervisors will list step-by-step guidelines including exactly what needs to be conducted and exactly how to conduct it using EPA and Department of Health guidelines. This full scope, including the step-by-step guidelines will be supplied for you based on the results of your samples with guidance from the microbiologist. This will address any areas that are concerning. 

Additional sampling if needed, such as spore trap (air-o-cell) sampling, tape lift sampling, bulk samples, carpet vacuum cultured dust samples, culture swab samples and culturable Petri Dish cultured air samples are available at an additional charge. We work closely with Attorneys, Banks, Builders, Contractors, Home Inspectors, Insurance Companies, Mortgage Companies, Physicians, Property Managers, Realtors, Remediation Companies and many State and Federal Agencies. We will guide you until your problem has been solved, if you have one. We protect your interest as our client.

We can also help you if you already purchased the property and are having issue already and/or if issues are happening that weren’t disclosed. Our experts can detect many hidden issues. While you have options, the sampling and inspection by our Council Certified Inspectors will verify if anything is present that shouldn’t be. If something is present, we will provide you with an exact scope of what work needs to be conducted and exactly how to conduct it based on your results, visual inspection and using the Department of Health guidelines.

Mold and/or moisture intrusions often fail to make most seller’s disclosure list. New homes are also experiencing mold problems because of different reasons. Shoddy construction and defective products are contributing to the new construction home. The building materials are also left out in the rain. Families are suffering physically, emotionally and financially from hidden mold problems. Mold can destroy everything that is grows on. Disclosure is a law in all fifty (50) states. If an issue wasn’t disclosed, and then discovered, the seller is usually responsible.

Molds can gradually destroy the things they grow on and may compromise the structural integrity of the property. Is someone sick and you’re not sure why. All molds have the potential to cause adverse health effects as exposure time increases. It’s better to be safe than sorry. If the first step is done incorrectly, all the following steps will be done incorrect.

We get you scientific documentation of what’s present in the property, we can tell you if the air inside the property is unhealthy and if not, we will make recommendations of what needs to be done to alleviate the mold problem, if you have one. 

With the certified results report in your hand, (visual and/or mold laboratory analysis), you will have clear documentation of what needs to be done inside the property, if anything. You will also know what you are up against with no hidden factors. 


NAL East only does the testing. We hope the property is safe environmentally. We have no conflict of interest. We do the inspection with no desire to find elevated levels inside the property. But if there are, we will guide you with what needs to be done, if anything, from beginning to end. 

Most people are aware that outdoor air pollution can damage their health but many do not know that indoor air pollution can also have significant health effects. The Environmental Protection Agency (EPA) stated that the levels of indoor air pollutants might be of particular concern because most people spend about 90% of their time indoors. Most airborne particulates cannot be seen with the human eye. 

In fact, 98% of all airborne particles are less than one micron in diameter. Visible particles start at around 30 microns; the average human hair is 60 microns in diameter. Airborne mold spores are generally between 1 & 10 microns. These invisible particles tend to remain airborne for an extended period of time

It is extremely important to find out what is present and at what levels before any work is conducted inside the property.

Consider this, every state in the nation has a Vehicle Lemon Law providing a method of getting a complete refund for vehicle that cannot be fixed, yet not one state has a similar law providing protection for you, your family, and The Biggest Investment of Your Life.

The CENTER FOR DISEASE CONTROL ( CDC ) states exposure to damp and moldy environments may cause a variety of health effects. Some people are sensitive to molds. For these people, molds can cause nasal stuffiness, throat irritation, coughing or wheezing, eye irritation, or, in some cases, skin irritation. 

People with mold allergies may have more severe reactions. Immune-compromised people and people with chronic lung illnesses, such as obstructive lung disease, may get serious infections in their lungs when they are exposed to mold. 

In 2004 the INSTITUTE OF MEDICINE ( IOM ) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition. The IOM also found evidence linking indoor mold exposure and respiratory illness in otherwise healthy children.

In 2009, the World Health Organization (WHO) issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mold. Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies, but more research is needed in this regard.

NAL East currently follows the guidelines set forth by the United States Environmental Protection Agency (USEPA), the Delaware Department of Environmental Protection (DEDEP), the Maryland Department of Health (MDDOH), the New Jersey Department of Health (NJDEP), the New York City Department of Health (NYCDOH), the Pennsylvania Department of Environmental Protection (PADEP), the National Institute for Occupational Safety and Health (NIOSH), the Occupational Safety and Health Administration (OSHA) and the California Occupational Safety and Health Administration (CALOSHA).

NAL East only uses American Indoor Air Quality Council (AIAQC) Council Certified Environmentalists. Our environmentalists go through constant schooling and certification updating throughout the year. All inspections are strictly confidential and coded for your privacy. Payment is due at the conclusion of the inspection. You will have your full report within 24 hours.
