"I have been sick for 8 months with various lung , fatigue, EBV, breathing, I missed so much work my 13 plus year job fired me. So when I had this test done and found out that I had very high amounts of a asprigillius mold in my HVAC system and that there was a fairly easy inexpensive remedy and that I will feel so much better I was very happy of the choice that I made to hire this company. The company they referred me to to get what I needed to fix the problem was over the top helpful and could tell he loves his job. I have already referred to a friend who has already made an appointment. I can not wait to apply the remedy, it should be in the mail this week. Thank you Thank you Thank you."

"Had initially contacted them about testing and was pleased when they said that since they provided abatement, they didn't do testing. Their estimate was within the range of what the state asbestos program staffer had guestimated, and about 30% less than another Angie's A-lister we consulted. They offered us a reduction in the water/power charge since we lived close to their facility. Marcus communicated well and scheduled the work as early as possible since we had a time issue. He also acted quickly to help make the manifest for the disposal of the contaminated material available for the wrecking permit application."

"My house was being romodeled, and the work in my ktchen and bathroom wasn"t completely finished. It's cold in Minnesota and i guess pipes can freeze and burst. Well it did in my house, my entire first floor was flooded. I was alone with my kids, my husband was out of town, I had no idea what to do. I called a friend they said I had to call a plumber. Well not a single plumber I called could make it till next morning. no way was that goping to work with a pipe broken and water going everywhere. I went online and found these guys, I am so glad I did too. They had a plumber on its way, he fixed the break, and Water Out Pros were there shortly after the plumber was. They evaluated the problem, tested thngs, and told me what happened, what was effected and what needed to be done to dry it and prevent any other problems. let me tell yah these guys had an estimate and a plan in place before I could panick any further than I already was. They took out the damage in my house, saved what they could right off the bat, and started the drying process. They tested all the walls in the area of the break which was my entire lower level of my house. They cleaned it all up, dried my house and helped with all the forms, and insurance. I called a few other companys before these guys and to my extreme dissapointment the other companies wouldnt even come out until they knew how much they were going to make on the job. One company quoted me and he didnt even come out. The guys at Water Out Pro estimated lower and they were honest. After the initial night, and every drying day to come these guys continually tested, and checked on the equipment. My husband was pleased with the services and reports they gave us. I couldn't have asked for any thing better. They exceeded my expectations and took care of us, the right way the first time.

"The mold removal and restoration of my front hall closet was started and completed with no problems. I got everything in writing and the workmen did everything in a timely manner. Everything was cleaned up and you wouldn't even know they were there. I got a great value for the money and I thank them for not trying to take advantage of me. The employees were very professional, friendly, and helpful. THe closet looks beautiful now and be energy efficient now that the mold and moisture problem is gone - I can feel the difference."

Mold Testing and Remediation FAQs, answered by experts

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

Toxic black mold on wood appears as dark green or black patches. It often has a slimy or wet texture and may spread across the surface in a spotty pattern. The affected wood might appear discolored, soft, and damp. Identifying black mold early is crucial because it can cause severe health problems when its spores are released into the air. Prompt remediation is necessary to prevent further damage and health risks.

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
