"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

"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."

"My technician Tanner was extremely knowledgeable and friendly. After looking at my home and surveying for mold, I decided to have the air tested which he did right then and there. I am still waiting for the results but it was nice to know we had no mold issues."

"For those of you looking for an honest, kind, caring person in the world of “hazardous vapors” look no further than this company. Kevin at All Clean Environmental Services took my panicked call on a Saturday and listened in detail about health concerns regarding “moth ball odors” in my family’s rental property. With that he volunteered to come and “check out” the offensive odors. Kevin was very discreet as well as thorough in his handling of visit to “our” home. Having never dealt with this problem he was quickly in contact with his suppliers of treatment options."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Mold Testing and Remediation FAQs, answered by experts

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

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.

Homes should be checked for mold annually, especially if you live in an area with high humidity or frequent rainfall. Inspections are crucial following flooding, roof leaks, or plumbing issues. More frequent checks are necessary if your home has a history of mold problems or water damage. Regular inspections help detect mold early, preventing costly remediation and minimizing health risks, especially in moisture-prone areas such as basements and bathrooms.

Mold can begin growing in as little as one to two days after your ceiling has been exposed to water. Mold grows and spreads quickly and can cause serious health problems. Always ensure areas with leaks are fully dried out, and any damaged material is replaced to discourage mold growth.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay.
