"It was extremely stressful to have asbestos found in my lower level after flood damage. Having your house torn up is no fun. The guys from EnviroBate took away so much of that stress! They were so understanding, so professional, and so considerate of my time. The repeatedly accommodated my need to access various areas of the house in the midst of their work. They worked around multiple issues at my home and were so careful with my animals. One guy (Darin) even fixed my garage door and carried down a very heavy container of food for my animals. He also asked if their equipment would scare the animals and had me monitor the animals while he turned on various tools to make sure the animals wouldn't freak out. These guys are great and I'd highly recommend them!"

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"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

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Yes, a refrigerant leak is extremely toxic and dangerous to breathe. Refrigerants can displace oxygen in a room, which can lead to suffocation, loss of consciousness, serious health issues, and even death. You may also suffer from refrigerant poisoning, which can cause symptoms like headaches, nausea, dizziness, swelling of the throat or sinuses, vision loss, and a burning sensation in your eyes, ears, nose, lips, and tongue. If you experience any of these symptoms, you should seek medical attention immediately. In addition, refrigerant leaks are toxic to the environment and can cause permanent damage to the ozone layer.

Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.
