"Jon from MoldGone easily saved me more than a thousand dollars by providing an expert opinion on proposed mold remediation by another company. His response was very timely, and he actually turned down the opportunity to undertake work, saying that the situation did not warrant remediation by his company. It was very refreshing to have someone advise that their services were actually NOT required in this instance. Should I every have any future questions regarding mold remediation, Jon will definitely be my first call."

"Timely, efficient, response. Identified a minor mold issue and applied appropriate treatment. Poor quality filters on equipment left a film of fine dust everywhere near a vent. Recommend upgrading vacuum filters to finer screen."

"Bruce was very responsive to my call. We scheduled an appointment 2 business days after our first contact. Bruce was on-time and very professional. He looked at the basement and said it was a good waterproofing job and looked at the mold area - and it turns out its the type of mold we can remove ourselves by peeling the paint off. I couldn't be more grateful for his integrity in looking at our problem. Because of that I would call them again, use them and will highly recommend them to anyone I know who needs mold remediation."

"Mr. Rudd of Rudd's Indoor Environment and the service he provides are EXCEPTIONAL!. Mold can be a scary subject but if it is something you need to look into Mr Rudd is the man to look to. We used him to do a mold inspection for a home purchase. Very satisfied. He knows what he is doing and was very thorough, professional and very informative. At the same time he is easy to talk to and easy to contact if there are any follow up questions or needs. He often answered the phone right away, but if not, he returned my calls or emails quickly. He also made himself readily available for phone calls from any other involved parties (in our case the real estate agents) who need further explanations."

"We were given detailed descriptions of the proposed mold removal process, and all our questions were answered in a clear, coherent way. Photos (from a crawl space) showed us just how much mold had accumulated from the leaking pipe. The work was performed with safety of all concerned in mind. Above all, the two men who came into our home were pleasant, professional, and kind."

"We recently worked with Flood Solutions after our basement flooded, and Megan—our inspector and project manager—was incredible. She was thorough, patient, and took the time to explain every step of the process, which meant a lot as an allergy sufferer worried about proper remediation. She honestly deserves her own show on mold education! When the team arrived, they were organized, detailed, and clearly cared about doing things the right way. Matthew and the crew also did a fantastic job finishing everything and making sure we felt informed and comfortable throughout. We can’t recommend Flood Solutions enough. If you need a trustworthy team during a stressful time, call them—and hopefully you get Megan, she’s a gem!"

"This is not a mold remediation company. When you hire this company, you are simply getting a mold test. Be specific when you explain your problem and what you are looking to get done. The mold technician was in and out in 20 minutes. He took an air sample and one swab, that s it. For the price of $299. Once you get the results of your mold test, they refer you to a company that is in the business of selling mold remediation products. Originally as much as $1600 for mold bombs, sprays and commercial graded air scrubber. I negotiated down to $1195. Then settled on only what I needed. Know what you want, do your homework before buying products you do not need."

Customers say: Quick response

"The mold inspector was very knowledgeable regarding the mold inspection process. He took samples of mold area for lab evaluation and air quality samples to check for mold in the air around the affected area. I was impressed with the thorough process used to check for mold. Mr Riddick the owner checked the air outside that was in close proximity to affected area. He answered all the questions and provided a date for the results of the inspection. Mr Riddick did an outstanding job and would highly recommend him for his service."

Mold Testing and Remediation FAQs, answered by experts

Mold can be hazardous to your health. Some people are allergic to mold and experience a reaction when exposed to mold spores. The reaction varies from person-to-person, but can include a runny nose, skin irritation, and asthma attack. Mold can also be irritating to people who aren't allergic, causing respiratory, skin, and eye irritation. In some cases, mold exposure can lead to infections.

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

Both an air purifier and a dehumidifier can help prevent future mold growth, but neither can remove existing mold. An air purifier will improve air quality and trap mold spores in the air, whereas a dehumidifier will reduce moisture in the environment. Keep in mind that you need to make sure your air purifier uses HEPA filters, which are rated for mold removal.

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

Signs of mold sickness often manifest as respiratory issues, including coughing, wheezing, shortness of breath, and sneezing. You might also experience symptoms that resemble allergies, such as itchy eyes and sinus infections. Other telltale signs include skin irritations, persistent and unexplainable headaches, and mental confusion, often described as 'brain fog.' It's important to remember that mold can cause health problems even if it's not visible, as it can grow inside walls. If you are experiencing these unexplained symptoms, you may want to consider a professional mold inspection.
