"This was a great experience. I am very happy to have found Moldgone LLC. Everything was smooth from start to finish. The inspection was fast and simple, I received the quote quickly and the price could not be beat. They set the appointment and all communication in between were timely and informative. Jason & Curtis were my techs. They were friendly, fast, thorough, and did a wonderful job cleaning the model and repairing the area. I hope I never have mold again, but if I do, I will call them! Wonderful service and experience!"

"Our cleaner Stephan was very professional, nice and informative. He even installed a special blue light with our system to prevent mold.... the same day. Would definitely recommend. The price went up because we opted to have mold cleaning and light installed. But very needed service. The price started around $240.00."

"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."

Mold Testing and Remediation FAQs, answered by experts

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Yes, mold can easily grow under your hardwood floors, especially if your house has recently flooded or if there is a leak from a pipe under the floor. Hardwood floors can trap moisture beneath them, creating the perfect environment for mold to grow. Similarly, mold can also grow under your wood floor’s surface paint.

The primary difference is that black mold (Stachybotrys chartarum) is considered toxic and more dangerous than regular mold. It can produce harmful chemicals called mycotoxins, which may lead to severe health issues like respiratory problems, skin irritation, headaches, and other long-term complications. While regular mold is rarely toxic, it can still cause allergic reactions and respiratory irritation. Visually, black mold often appears dark—green, gray, brown, or black—with a fuzzy texture, whereas regular mold can be almost any color. Black mold is less common and typically grows in areas with severe water damage. Regardless of the type, you should not ignore any mold infestation in your home.

Slime mold will go away on its own within a few days to a couple of weeks. Generally, there is no need to use chemicals on this matter. If you want to get rid of it right away, rake over the slime mold and the surrounding area or hose off large patches of it.
