"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."

"Daniel was great to work with. He called when he said he would. He showed up for the testing on time. Explained what he was doing. He did a very thorough check for moisture behind the walls and air samples where needed. He really showed that he knows what he is doing. If I ever need a mold inspection done again I ll be calling Rudd to do it."

"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."

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

Yes, limewash is free of volatile organic compounds (VOCs). Made of lime and water, it is eco-friendly, breathable, and toxin-free. Most synthetic paints have low to high levels of VOCs, which causes their irritating odor, which can have adverse and long-term effects on your health. Conversely, limewash consists of crushed limestone, which undergoes burning, mixing, and aging before being diluted with water—natural pigments add coloration.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

The high humidity of steam showers creates the ideal environment for mold growth, so it’s important to stay proactive against it. Along with regular cleaning, run your bathroom fan during and after your steam shower. Keep your shower door open and any doors and windows in the bathroom to allow the space to air out properly. If you come across ugly mold spores, spray them with undiluted vinegar, let it sit for at least an hour, and then scrub away the mold.

Yes. Over time, hidden moisture from a leak in your bathroom may lead to black mold, requiring a mold remediation company’s services and the removal of large wall sections, which can be costly. For example, 100 square feet of drywall can cost as much as $400 to replace, while mold remediation can run anywhere from $500 to $3,000.

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.
