Do you handle both mold inspection and mold remediation (removal)?

No. Certified Indoor Air strictly specializes in inspection and testing. Handling both is a direct conflict of interest and is illegal in many states. By focusing entirely on assessments, we provide an unbiased, honest evaluation without trying to sell you costly remediation services.

What does your comprehensive mold inspection process include?

Our Clean Air Protocol follows four distinct steps to ensure accuracy: Inspection: A thorough indoor and outdoor evaluation checking for moisture, water damage, structural issues, and HVAC/duct vulnerabilities. Testing: A customized sampling plan using options like air spore traps, ERMI, surface swabs, or tape lifts. Analysis: Samples are processed by an accredited third-party microbiology laboratory for legally defensible data. Reporting: A phone consultation to explain the findings,and recommended remediation. Detailed written report is available as an additional service if remediation is recommended at customer request.

What is an ERMI test, and how does it differ from standard mold testing?

An ERMI (Environmental Relative Moldiness Index) test is a highly sensitive method designed by the EPA. It analyzes dust samples to detect and quantify 36 specific species of indoor molds, successfully differentiating between toxic and common molds. It provides a deeper look into the historical mold burden of a home than standard air sampling alone.

What other indoor air quality and environmental hazards do you test for?

In addition to comprehensive mold testing, we test for a wide range of environmental illness triggers, including: Mycotoxins Endotoxins Bacteria (including actinomycetes and streptomycetes) Volatile Organic Compounds (VOCs) a Formaldehyde Indoor allergens

Why is indoor mold such a prominent issue in the Carolina region?

While over half of all buildings in the U.S. have sustained some form of water damage, the Carolina region experiences a daily average of 70% humidity year-round. This constant high humidity creates the perfect environment for indoor mold to thrive.

How quickly can I expect to receive my testing results and final report?

We prioritize fast turnarounds. Lab results from our third-party accredited facility are typically returned within 3 business days. Once the data is in, we will schedule a phone consultation to explain the results immediately. The phone consultation provides translation of the lab data and verbal recommendations. A full, comprehensive report containing observations, photographs, and custom protocols is an extra service that can be provided shortly after.

What geographic areas do you serve?

We proudly serve residential and commercial clients across the region, including Raleigh, Apex, Cary, Chapel Hill, Clayton, Durham, Fuquay-Varina, Garner, Holly Springs, Knightdale, Morrisville, Pittsboro, Rolesville, Wake Forest, Wendell, and Willow Spring.

Our Clean Air Protocol

Inspection

We start by conducting a thorough inspection of your home or building. We examine your property's exterior and interior to search for points of moisture infiltration, past and present water damage, structural abnormalities, and signs of mold growth. We check your ducts, HVAC system, sinks, pipes, skylights, appliances, and potential water sources.

Testing

Once the inspection is complete, we devise a sampling plan for sample collection from your home; specific to what was learned during the inspection. Some testing options we use are air spore traps, ERMI, HERSTMI-2, and surface sample swabs or tape lifts, dust sampling and VOC testing.

Analysis

We send your samples to a leading commercial accredited microbiology laboratory for third-party analysis. You will receive accurate, complete, and legally defensible data within days of sampling.

Reporting

Once the test results are in, a telephone consultation with you is the final step to your understanding the results and their implications. A comprehensive report, including test results, photographs, inspection observations, and proper remediation protocols is also available if needed.

"Great experience! Bill responded quickly to my emails and gave me a good overview of the process. When he got to the house, he asked questions to better understand our concerns and goals. He was thorough and knowledgeable. He made some recommendations based on his visual inspection and then followed up with a report showing the air sample results. I had some questions after the inspection and he took the time to explain. Highly recommend."

"I reached out to William at Certified indoor air in regards to a mold inspection. I received a fast appointment and a environmentalist with a great personality. Upon my first call with William he listened to my problem and greatly understood my concerns he shared helpful insights in regards to mold and understanding the inspection process.

During the inspection William educated my family and I on understanding mold formations. He did a home inspection indoor and outdoor and took samples. I received my results relatively quickly. Once my results were received William reached out and explained the results in great detail and also provided feedback with visuals and a terminology reference that enhances the understanding of the results. I would recommend Certified indoor air."

"William Dolch did an excellent job in educating me on the proper test needed for our problem. Then he properly took the samples and proved the high level of toxic mold that was in my dad's apartment due to water damage. I highly recommend his services as he is very knowledgeable, professional and hard working. I'm thankful that I made the right choice to hire him and listen to his recommendations."

"I hired them to inspect a house for mold before I purchased it. They were extremely thorough. They got me the test results back quickly but the full report took longer for them to write up. It was within the time limit I was working under but I do recommend confirming with them about what the timeline is especially if you have a tight timeline. Bill Dolch was very helpful in terms of explaining the report in full to me. I would hire them again."
