"Henry came to our house. He was very knowledgeable about mold and what to look for. He answered all my questions and was very helpful. Peter who called me with the results was very nice and answered my questions. He even called back the next day when he noticed that an email he sent me didn t go through. They gave me a lot of information to help me continue my search to get rid of my mold and poor air flow."

"For anyone looking for a reliable and honest company- I highly recommend Pacific Pure Maintenance. After having exposure to TOXIC mold in my home, I had Pacific Pure Maintenance quote the project for mold remediation. My insurance company however, had me go with another company that cut and removed the mold without doing any kind of treating to the air. Months later I was still ill and contacted Pacific Pure Maintenance and they were very knowledgeable and helpful. They removed the toxins /air spores that were continuing to make me sick. (Something that other companies did not do NOR recommend). At the time, I knew NOTHING about mold exposure and I was looking to the experts for advise and none of the other mold removal companies were as helpful as Pacific Pure Maintenance. I am forever grateful to this company for doing what other companies didnt and going above and beyond."

"Rick, the owner of Ovation put us instantly at ease. His suggestions led us to not only remodel our bathroom, but extend remodeling to the rest of our home. Our first meeting, and every interaction following with Rick's crew was positive. They came, they worked hard, always smiling and were very flexible towards our needs. We heard how much they thought of Rick and his wife Jessica, which only confirmed we made the right choice. Issues came up, which we didn't count on, and I'm embarrassed to admit Rick & Jessica were on the receiving end of my stress, but despite this, Rick always remained patient, and even Jessica called to reassure me she was working on it. In the end, my whole house was completely made over with new bathroom cabinets (including linen storage) flooring, doors, trim, molding and paint. The quality of our remodel has turned our home into an amazing staycation. We hope to have Rick & Jessica over for dinner, not only because Rick is a was, but because we want to show our gratitude"

"The experience with Justin at Fire & Water Damage Recovery was excellent. They were referred by the plumbing company that serviced my sump pump. We still got 3 estimate, Justin's estimate was in the middle but I felt good with Justin based on our phone conversation and the referral so we went with this company. Justin did tell me that he might have estimated on the high side because he does not like to surprise the homeowners. What a surprise when I go the final invoice. The final invoice came in much lower and was very close or lower than the lowest estimate I got. Justin and his team also took pictures of how the place was before and after for me to see. They even took pictures of the pathway that they took to get to the crawl space to assure me that they kept the place clean when they got in and out. I was very satisified with Justin and his company."

Mold Testing and Remediation FAQs, answered by experts

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.

Mold loves a moist environment, so the best way to keep it from returning is to keep your machine as dry as possible. Take laundry out of the machine as soon as you can after a cycle finishes. If your laundry room is humid, consider using a dehumidifier or at least running a fan to increase airflow.

It's also a good idea to leave the washing machine door open when it's not in use, to improve airflow and keep the interior dry.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.
