Not a Marketplace, Only Cleaners

Unlike companies using contractors, Slate employs its cleaners, ensuring they receive comprehensive training, management, and legal protections. This approach enhances job performance, reduces staff turnover, and maintains consistent quality over the long run.

CIMS Certified

The gold-standard in commercial cleaning certification. There are over 1 million cleaning companies in the US and only 400 are CIMS-certified. That's less than 0.05% of all cleaning companies in the US.

Amazing Support

Whether you are on Slack, SMS, phone or in-person our friendly, knowledgeable, proactive team works as an extension of yours.

15 Profitable Years in Business

Good housekeeping starts at home. 15 years of profitable operations means we run a tight ship at home. We answer only to our clients, not to investors.

Fully Insured

The most comprehensive insurance coverage so you can have peace of mind that your space, things and people are covered.

Give Back

We partner with community organisations throughout the US to both source employees and support them financially.
