"The best decision I’ve made in a while was to go with Omega to fix my home! Unfortunately my home was flooded. I tried to fix it myself, but once I came across mold I felt it was important to hire an expert. I got a quote from Enver which was very fair, and I was elated by the service he offered. He approached the job with integrity, professionalism and expertise. My home is now even better than it was before the flooding, and it’s all due to Enver and his team. I highly recommend them for your home!"

"Working with Lee and his team has been a truly exceptional experience! I personally had mycotoxin so I understand the dangerous and debilitating effect mold can have on peopleâ s lives. We hired Lee and his team for mold inspection when we were considering buying a house. We contacted Lee when we were on day 3 of our 10-day inspection period. Despite his busy schedule, Lee squeezed time to come by the house. Professional and patient, Lee answered all my questions with expert knowledge regarding the test results and the proposed remediation plan. The house we were trying to buy doesnâ t have mold to an alarming level, but I was determined to rid of them for my familyâ s health. Lee and his team did an excellent job for the remediation and they shared so much professional knowledge with us, which I greatly appreciate. We liked their work ethic so much that we hired them again to do HEPA vacuuming for the house after some remodeling projects. Again, Lee always patiently answered every single one of my questions with great depth of knowledge. We had some issues with contractor delays and Leeâ s team was very understanding and accommodated our updated schedules several times with their very busy schedule. The ozone treatment has greatly reduced the odor from remodeling, which was already minimal from using zero VOC paint and flooring. Again, we liked their work so much that we asked for their help to deodorize our new car. Lee and his team are exceptional not only in their expertise knowledge in mold but also their work ethic; they are punctual, they prepare their clients before each visit, and they follow up after each visit. We cannot say enough praise about Lee and his team!"

"We discovered we had mold in our home after we had a leak. Matt and his team tested our home for mold, then we completed the dry fog remediation treatment. They gave me post tests to show the mold has all been killed. They were very thorough everything went just as planned. Excellent job, I am very impressed!"

"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

Mold Testing and Remediation questions, answered by experts

A mold inspection, especially in homes with a history of water damage or high humidity, is critical for maintaining a healthy living space. Mold can cause respiratory issues, allergic reactions, and other health problems, particularly for individuals with asthma or weakened immune systems. Unchecked mold growth can lead to structural damage, resulting in costly repairs. A thorough inspection identifies visible mold and uncovers hidden sources to allow for timely remediation, preventing further damage and health risks.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

Yes, brown spots on a ceiling are usually caused by water leaks and can lead to mold growth, especially if you don’t correct the underlying problem. Ongoing water leaks and moisture issues will almost always result in mold growth, especially if you live in a warm climate. Mold is a health hazard, so get the root problem fixed quickly, clean it, and encapsulate the area to avoid mold formation.

Mushrooms do not harm your yard. In fact, they can actually help improve your lawn health by decomposing woody organic matter in your soil, and breaking it down into nutrients that feed your grass and plants.

You can find the smell of mold in your house in two ways: following your nose, and using common sense tactics like looking anywhere there’s water first. Mold cannot form in a completely dry environment, which is why you see mold much more often under kitchen sinks than on garage floors. If you have looked everywhere and still can’t find the source, hire a pro, because you may have mold in your walls.
