Tired of Unreliable Cleaning Companies?
Your cleaning company stopped showing up.
It's the most common complaint we hear. At Diakonos, every facility gets a written cleaning plan - so expectations are clear from day one.
You call and nobody picks up the phone.
When you work with Diakonos, you're talking directly to us - not a call center. Our team is a phone call away, and we check in regularly to make sure things are right.
They cut corners and hope you won't notice.
We treat the people pushing the mop with dignity and give them the support they need to do the job well. Happy people clean better - and that shows up in your facility.
