The History of Signal Hygiene, LLC
Founded on innovation and a commitment to solving complex indoor environmental challenges, Signal Hygiene was born from a simple observation in 2014: there were few safe, effective solutions available to eliminate persistent odor-causing contaminants and prevent them from returning.
Working alongside leading chemical engineers, Signal Hygiene developed proprietary products and application protocols capable of eliminating a wide range of odor-causing particles while providing long-lasting protection. This technology evolved into what is now known as the Signal Hygiene System®—a proven process designed to identify, eliminate, and help prevent the return of environmental contaminants.
Since 2017, the Signal Hygiene System has delivered successful results in residential, commercial, industrial, and institutional environments. Our specialized products and protocols have addressed numerous root-cause issues, demonstrating their effectiveness through both real-world and clinical applications.
A major focus of Signal Hygiene has been improving indoor air quality through HVAC system cleaning and treatment. Our technicians have successfully eliminated stubborn odors and contamination issues in air handling units and ductwork where other methods had failed. Through ongoing inspections and customer feedback, we have consistently verified long-lasting results that often exceed expectations.
Today, Signal Hygiene provides professional indoor environmental services including mold inspections, mold remediation, odor remediation, crawlspace encapsulation, crawlspace environmental corrections, and HVAC system Dirty Sock Syndrome treatments. Our mission remains the same: delivering effective, long-term solutions that create healthier indoor environments for homeowners and businesses alike.
To expand access to our proven system, Signal Hygiene, LLC offers franchise opportunities throughout the United States, providing comprehensive training, operational support, specialized equipment, proprietary products, and ongoing guidance to franchise partners.
The Signal Hygiene Promise
What Customers Say About Us:
D Lombardo says: “The service provided was worth the money spent. For over 20 years our HVAC vents had never been cleaned out and the dust and dirt that accumulated was unbelievable. There was no telling how much of that was being thrown back in the air and we were breathing it in. Brady spent the entire day cleaning the entire vents and duct work and filter. The job was done right, and the difference is amazing. The air is cleaner that we breath; for some reason my monthly electric bill is lower; and there is a fresh clean smell when the air or heater unit is running. I highly recommend SignalHygiene. They don’t just come out with a vacuum cleaner. They have the tools and time to do it right.”
B Hill says: “I am a property manager responsible for over 150 units. Our company manages over 2,000. Signal Hygiene is our go-to for inspection and remediation of all things “M” – mildew, musty smells, moisture issues, or mutt (and feline) odors. Brady is extremely easy to work with, responsible, and knows how to discuss things with both us, and the resident! With nothing more than an email he is on the job, scheduling his inspection, getting an estimate back quickly with pictures or videos, and stands behind his work. My job is easier thanks to Signal Hygiene!”
Anonymous says: “I’m a Mechanical Engineer at a hospital. We had some significant issues in a facility and tried many companies and so-called solutions to fix the problem but nothing had any lasting results. Then I tried The Signal Hygiene guys. After a single treatment, the problem was completely gone and hasn’t come back in over two and half years. They’re discrete, usually performing services during third shift, the technicians are unmarked as is their trucks and trailers, and they don’t talk to other staff or patients. These guys truly produce amazing results.”
