State Of The Art Mold Inspection And Testing

State of the Art Mold Inspection

Orange County is a vibrant and beautiful place to settle down. It has plenty to offer homeowners, from sunny weather and beautiful beaches to outstanding hiking trails. Still, no matter where your home is located, indoor mold can creep inside and cause many different issues for homeowners (and renters).

Mold plays an essential role in maintaining Orange County’s beautiful ecosystem, but it’s not something you want in your home. Indoor mold can grow in any area of a home that has been exposed to moist or damp air. If left unaddressed, indoor mold will likely spread to other parts of your home and cause structural damage. Mold can also contribute to poor indoor air quality and health concerns, such as respiratory illnesses, allergies, and memory loss.

How Do You Know if You Have a Mold Issue?

Humid air and heavy rainfall in Orange County can contribute to mold growth, especially in cool and dark areas, such as your home’s attic. Musty odors and discoloration on furniture and carpets are also signs of mold growth. If you suspect there is mold in your home, Guaranteed Property Inspections can help. We provide expert mold inspections and mold testing services to homeowners throughout Orange County.

Our team of expert mold inspectors will search your entire property for mold growth. We will then provide you with a written report indicating where the mold was found and what types were present. You can read more about our mold inspection services here.

Frequently Asked Questions

The average on-site inspection time for a single inspector is two to three hours for a typical single-family house. Anything significantly less may not be enough time to perform a thorough inspection.

Mold testing cost is dependent on many different factors. For instance, types of mold testing that may be required and how many different samples are needed depends on what type of condition the property is in, has there been current or active leaks? Have there been any water losses? The only way to answer these questions is by completing a comprehensive mold inspection on site. This allows the hygienist to pinpoint and locates each individual area of potential contamination. The comprehensive inspection is the key component in determining the source of the contamination and the presence of mold. The site assessment also allows us to develop a mold sampling protocol that will best fit the client's needs. Comprehensive mold inspection cost depends on the square footage of your property. With that vital information, we can provide clear pricing to complete your mold inspection and mold testing.

An asbestos survey is required prior to any demolition or renovation of any structure no matter the year the structure was built. The only exception to the survey requirement is the renovation activity of residential single-unit dwellings (houses) in which less than 100 square feet of the surface area of intact (not damaged) material is removed or stripped. ACAC or Certified Site Surveillance Technician (CSST) is trained to be able to identify homogenous-suspect materials and can presume or assume the material is Asbestos-Containing Material (ACM).

Symptoms related to poor air quality exposure vary from person to person. In most cases, individuals with a weakened immune system, immuno-compromised, autoimmune disorder, asthma, cancer, or allergies show worse exposure symptoms compared to a healthy individual. However, prolonged exposure to mold contaminants and toxins can have adverse health effects on anyone exposed to it. Some exposure symptoms include respiratory distress, coughing, skin rash, sneezing, sinusitis, difficulty swallowing, choking, spitting up (vomiting) mucous, Hypersensitivity pneumonitis, Asthmatic signs; wheezing, shortness in breath, coughing, burning in lungs, etc., Irritable bowel syndrome, nausea, diarrhea, sharp abdominal pains, stomach lesions, Memory loss; brain fog, slurred speech, Thyroid irregularities, Headaches, Chronic fatigue, Reproductive system complications, and Seizures, inadvertent body jerking, twitching.

Air quality testing can detect a number of airborne contaminants. Some of the more common contaminants that air quality testing shows are: Identification and enumeration of fungal spores, total dander, fiber and pollen counts, cellulose fibers, dander, fiberglass, and other particles that may affect indoor air quality and bacteria and viruses.

“Demi so was helpful when I called in to inquire about getting my property inspected. Joe showed up the next day on time and spent a few hours thoroughly inspecting my property, in which he did find mold growing. I’ve been having some serious health problems and feel such a sense of relief that I hired GPMI to help me get to the bottom of it. I will definitely use them in the future and would recommend them to anyone looking to get an inspection done”

I'm glad to say that I was able to find this company to help me with my new apartment I just moved to Fullerton and unfortunately I am in an older building with a lot of issues. The gentleman that came out was very nice and found a couple areas of water issues that I didn't even know about that had some mod growth. He was very thorough with my place being so small I think the time he spent was a lot trying to really find any problems that I could address to the property management which they took his report and did make the necessary repairs for me! Thank you guys!

I recently hired Joseph from GPMI for a mold inspection, and I can't recommend him enough. He is incredibly thorough and a true expert in his field. He was able to pinpoint every source of moisture in the rental property—a crucial skill since many property management companies aren't upfront about past water damage.

I'd been experiencing severe brain fog, allergies, and worsening autoimmune symptoms. My doctor insisted on a professional inspection, especially because of my specific genetic predisposition (HLA genetics, CIRS)—if you know, you know. Joseph is exactly who you want for your air quality testing and mold inspection. He's incredibly knowledgeable and a true professional.

We're exposed to enough pollutants and toxins in our daily lives through food and the air outside. The least we can do is invest in our health to ensure our home is a safe space with good air quality. For me, investing in my health is a non-negotiable—I'll gladly give up other wants in life because when I don't feel well, nothing else matters.

If you're dealing with symptoms that might be linked to mold exposure, or if you simply want to ensure your home is a healthy environment, don't hesitate. GPMI saved me from further damage to my health. Don't be afraid to stand your ground to protect your well-being, even when facing resistance from your landlord.

We couldn’t be happier with our experience working with Guaranteed Property & Mold Inspection. Even before our inspection, Demi went above and beyond to make sure we fully understood the inspection process and felt comfortable every step of the way. Her warmth, professionalism, and attention to detail were clear from the start—she answered every question patiently, listened carefully to our concerns, and provided clear and reassuring explanations.

Demi’s genuine commitment to our satisfaction truly set her apart. She coordinated everything smoothly, made herself available for follow-up questions even at odd hours, and worked with us to see how things were going even after the inspection was complete. It’s rare to find someone who cares so deeply about their clients and takes such pride in their work.

We also want to extend our sincere thanks to Joseph for his part in our experience. He gave us direct communication during the process. Their professionalism, integrity, and thoroughness exceeded our expectations.

We highly recommend Guaranteed Property & Mold Inspection to anyone seeking honest, reliable, and caring service for their property needs. We are grateful for their help and wouldn’t hesitate to call them again in the future.

I had a severe water leak due to my bathroom not being waterproofed correctly which caused moisture and mold issues. Joseph and Demi provided me with the reports I needed in order to hold my contractor liable for his faulty work. They were a pleasure to work with and went above and beyond to help us through this unfortunate problem. This company is among the very few of certified professionals that is approved for legal court documentation requirements.
