"Very pleased. Result was non toxic mold we could address ourselves. They gave us advice to correct the cause and took photos for us to give to carpenter we used to replace the section of the wall with the problem. They said to call back if any problems or concerns. Would definitely use again if any future problems. Thank you."

"They do both mold removal AND restoration. (Not everyone does both!) They arrived when they said they would. Their pricing was 30% less than the next bidder. They explained what they were doing along the way. I even tried to fix Mateo up with my daughter."

"If we could give our technician, Paul, 10 stars we would. Paul was so conscientious and detailed in cleaning our sectional sofa. The floors were covered to prevent any residual spray products from getting on the floor. The house trim corners were protected from hose scraping. When the work was completed, everything was left in pristine condition. The company was good at communicating the scope of the job, sent reminders about the scheduled time & date, and thoroughly explained their pricing process."

Mold Testing and Remediation FAQs, answered by experts

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Mildew starts as a tiny spot, but if left untreated, it can severely damage your home as well as cause life-threatening health issues. Mildew eats away materials like wood and drywall and if left untreated can destroy entire walls and buildings. Mold sickness is almost a guarantee if you don’t tackle this problem as soon as it rears its head.

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.

The gasket and drum of a washing machine are ideal spots for mold to grow. They are dark, warm, and humid, conditions that mold thrives in. The products you use to wash your clothing, such as fabric softener and detergent, can also encourage growth by giving the mold a food source.
