Art Gallery & Museum Cleaning Service Seattle

about us

Slate ❤️ Art Galleries and Museums

Let your clients and visitors focus on the art, not the dust. We’ve Made Professional Cleaning Our Fine Art.

Your visitors' focus should be on your artwork and artifacts, not the places dirt attracts. Slate offers art galleries and museums the cleaning services needed to draw attention to all the right places. Slate’s Keepers are licensed and insured, providing trustworthy cleaning services for the preservation and conservation of your collection.

Slate Keepers are licensed and aware of the appropriate cleaning methods to keep collections safe when wiping down display cases, sweeping floors, dusting dirty areas, and spraying any type of solution in a gallery or museum.

Our Keepers all undergo background checks and are able to follow any security protocols your art gallery or museum may require. Our goal is to protect the longevity and integrity of your exhibits. Let us know how we can best meet your 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?
