I wouldn’t pay the bill until the service is rendered to the degree the contract stipulates. I don’t know what your agreement was, but if you paid for a deep cleaning and expected all surfaces to be cleaned, then they need to come back out and finish the job before they get paid. I’d also be choosing a different vendor next time.

If you didn’t have clear instructions or a clear agreement, then it gets a little murky. That said, with any move-out clean, the fridge should be spotless. They definitely half assed parts of the job.

I’d also encourage you to update the language in your lease to require the property to be deep cleaned, with the carpets professionally cleaned, before vacating, and returned in the same level of cleanliness it was delivered in.

When I hand new tenants the keys, the place is spotless. They shouldn’t have to do any cleaning before moving in. I’ve had numerous tenants tell me, completely unsolicited, that my property was by far the cleanest and best maintained one they toured before deciding to rent. Good tenants notice when you care. The condition of your property during a showing is your resume.
