Mold Remediation
Mold is more than an unsightly nuisance — it can damage your property and pose serious health risks to you and your family. In Arizona's monsoon season, elevated humidity and moisture intrusion create ideal conditions for mold growth. STOS Environmental LLC provides professional mold remediation across Phoenix and all of Arizona, safely removing mold and preventing its return.
Our licensed, insured, and bonded team identifies the source of the moisture problem, contains and removes the mold, and restores your indoor environment to a safe, healthy condition. If you see or smell mold — or suspect hidden growth — we're here to help.
Mold remediation is the process of safely removing mold and addressing the underlying moisture problem that allowed it to grow in the first place. Simply cleaning visible mold isn't enough — if the moisture source isn't fixed, the mold will return. That's why our process begins with a thorough inspection and moisture assessment to identify not just where the mold is, but why it's there.
Once we've identified the source — whether it's a leak, poor ventilation, flooding, or high humidity — we contain the affected area to prevent mold spores from spreading during removal. We use negative air pressure, containment barriers, and proper PPE to protect you and our workers. We then physically remove contaminated materials and thoroughly clean and treat affected surfaces using professional-grade antimicrobial solutions.
Arizona's monsoon season is peak mold season. Summer storms bring heavy rain and high humidity, and if water intrudes into a home or business and isn't dried quickly, mold can begin to grow within 24 to 48 hours. Hidden mold behind walls, under flooring, or in attics and crawl spaces is especially dangerous because it can spread unnoticed for weeks or months. That's why water damage restoration and mold remediation go hand in hand.
The health effects of mold exposure can be serious, ranging from allergic reactions and asthma attacks to respiratory infections and other illnesses, particularly for children, the elderly, and those with compromised immune systems. Even if you can't see the mold, a persistent musty odor is a telltale sign that growth is present somewhere. Ignoring it only allows the problem to worsen.
STOS Environmental LLC combines mold remediation with environmental testing and air quality monitoring, so you know the job was done right. We can test for the type and extent of mold before and after remediation, verifying that your indoor air is clean and safe. We serve residential, commercial, and industrial properties throughout the greater Phoenix area and statewide.
