Deep Cleaning (Seasonal Cleaning)
(Seasonal, Periodic & Tenancy Turnover Cleaning)
Deep cleaning, also known as seasonal cleaning services, provide an intensive, periodic cleaning solution designed to restore commercial spaces and offices, not just maintain them. These services target areas that are not typically addressed during routine janitorial cleaning, including hard-to-reach, high-use, and buildup-prone areas.
Deep cleaning often requires specialized equipment and tools, such as steam cleaners and industrial floor machines, along with additional labour and hours to achieve a higher level of cleanliness. Services may be scheduled quarterly, semi-annually, annually, or as needed, including for tenancy turnovers, post-project refreshes, or seasonal maintenance.
