"We live in Glendale and had mold growing around a window that had apparently been leaking during rainstorms for years. LeakSafe Homes handled the mold remediation professionally and explained every step in a way that was easy to understand. The containment setup and HEPA filtration system made us feel comfortable staying in the house during the process. Very trustworthy company."

"Pure Restoration does it all and does it all to perfection. Tommy is smart, creative, artistic, and honest. He knows how to push through insurance claims when the denials start rolling in. He knows how to solve problems. Most importantly, he is a good person with good intentions. He understands the way of our world where quality work and customer care matter. Pure Restoration basically reconstructed my home after a horrible combination of fire and water damage. I am married with two small kids and uprooting us from our home was stressful, but Tommy did not add to the stress. In fact, his demeanor is naturally calming, he naturally cares about people, and he tries to instill good vibes. Also, the office is always there. They are one email away. The crew is also the most trustworthy crew that I can imagine. All in all, they are a model company."

"All work was completed on time with exceptionally high-quality work. All workers were introduced to me, making me comfortable with strangers in my home. All workers wore masks and used all health recommendations. I was brought into every step of the process and the process was explained. The total cost was as estimated. The price was about half of the estimate of other contractors. I was very satisfied. I recommend this business."

Mold Testing and Remediation FAQs, answered by experts

Bad odors and actual, visible mold aren’t the only ways to tell if your floorboards are suffering from too much moisture. Everything from high humidity to direct contact with water can cause wood to buckle, warp, peel, and discolor. Spotting one or more of these signs could be a clue that you’re dealing with mold. 

Mold can come back after cleaning, especially if the conditions are right. Mold loves moist environments, so if you clean a piece of furniture, then put it back in a humid area, the mold can return. Mold may also return if you missed an area during cleaning. A professional mold remediation company can help ensure that the mold is gone for good.

Certainly, DIY mold tests are not perfect when trying to determine whether you have a mold problem. They could give you a false positive reading, or they may fail to detect mold that’s behind a wall, especially if the infestation is still small. Ultimately, you should seek a mold inspection if the DIY test gives you a positive result, just to be certain. And if the test is inconclusive, it’s probably worth seeking an inspection from a pro.

A funky smell is the first indicator that mold or mildew is present in your home. You may also notice that you or your household members are suffering from increased allergies or respiratory issues. You should check the most obvious areas first—like your bathroom or anywhere there might be leaks—and if you still can’t locate the source, look under the floorboards. 

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.
