about us

Slate ❤️ Offices

We'll do the dirty work, you do your work. Slate focuses on cleaning your business so you can focus on running it. Go ahead, take cleaning off the to-do list. We’ve got it covered from here.

Maintaining cleanliness and hygiene in the office is made easy with Slate. Our Keepers clean everything from high touch surfaces to lesser noticed nooks and crannies in break rooms, common areas, and beyond.

At Slate, we pride ourselves for exceeding expectations. Our services include waste management, floor maintenance, restocking assistance, and filling any other cleaning need you may have.

Book your first appointment to find out how Slate can best meet your office cleaning needs.

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.

They solved cleaning already. When will you?
