Wherever possible the Viroklenz technicians will install in the silent hours to avoid disruption to your normal routine. Where this is not possible (e.g. care homes) we will work closely with the local management to carefully plan and ensure a smooth installation with the minimum disruption. The Viroklenz technicians will request that rooms be entirely vacated for the fogging procedure which generally takes only a few minutes per room and personnel can return to the room 45 minutes after completion.
