Frequently Asked Questions
Antimicrobial treatment targets and eliminates harmful bacteria, viruses, mold, and fungi from surfaces, preventing their growth and reducing the risk of illness. Using advanced cleaning solutions and high-temperature steam, we neutralize microbial threats at their source, ensuring your home or business remains a safe and sanitary environment. This treatment is especially important in areas with high moisture, frequent human contact, or post-flood contamination, as these conditions allow bacteria and mold to thrive.
Yes, our professional antimicrobial treatments are safe for families, children, and pets. We use non-toxic, hospital-grade solutions that effectively sanitize without leaving behind harsh chemical residues. Unlike store-bought disinfectants that provide only temporary relief, our treatments offer long-lasting microbial protection while being eco-friendly and safe for indoor use.
The effectiveness of antimicrobial treatments depends on various factors, including foot traffic, environmental conditions, and surface type. While our treatments provide long-lasting protection, we recommend scheduling regular cleanings for high-touch areas like kitchens, bathrooms, offices, and medical facilities to maintain a sterile and hygienic environment.
Absolutely. Mold and mildew thrive in moist environments, leading to unpleasant odors, respiratory problems, and structural damage. Our antimicrobial solutions penetrate deep into surfaces, killing mold spores and inhibiting future growth. This treatment is especially crucial for post-flood cleanup, humid climates, and damp basements, where mold can develop rapidly if left untreated.
Yes, commercial spaces, offices, medical facilities, and gyms can all benefit from professional antimicrobial treatments. High-traffic areas accumulate bacteria, viruses, and allergens, increasing the risk of illness among employees and customers. Our specialized treatments help reduce contamination, improve indoor air quality, and create a healthier environment for everyone who enters your facility.
Standard cleaning removes visible dirt, dust, and debris, but it does not eliminate bacteria and viruses at a microscopic level. Our antimicrobial treatments go beyond surface cleaning, actively destroying pathogens and providing an extra layer of protection against future microbial growth. It’s an essential service for those looking to maintain a truly sanitized and germ-free space.
If you’ve recently experienced water damage, persistent odors, visible mold, increased allergy symptoms, or frequent illness in your space, it’s a sign that bacteria and microbes may be present. High-traffic environments and areas with pet activity, food preparation, or shared surfaces also benefit greatly from professional sanitization. Our team can assess your property and recommend the best antimicrobial treatment plan to keep your space clean, healthy, and safe.
