Water & Air Hygiene
Protecting people through minimising risk, delivering compliance, and making it simple
Water and air hygiene is essential for every building across every sector. At andwis, we partner with you to deliver expert remedial treatments and planned preventative maintenance to help you stay compliant and protect the health and safety of your people.
Common water risks, such as Legionella, Pseudomonas, and scalding can pose serious health threats if left unmanaged. Similarly, dust and debris build-up in ductwork doesn’t just reduce air quality, it can increase the risk of fire and system inefficiency too.
With regular risk monitoring, planned preventative maintenance, and effective remediation, combined with professional commissioning of water and air systems, we create safe, healthy, compliant environments for buildings across the sectors.
