Hear from Satisfied Clients

I appreciate the diligence and professionalism of Anthony and the crew member appointed to us. During these covid times they have taken the upmost care to provide the level of cleanliness and safeguarding measures needed to insure everyone's safety. The pricing is fair and we are happy with the great service!
St. Joseph Church

My law firm hired National Janitorial to do some deep cleaning/disinfection after one of our staff was diagnosed with COVID. We called several businesses for pricing and availability for professional sanitation. National was the best pricing and was available that same day. They were great. Two guys arrived, both had sanitation equipment and sprayed down the entire office in less than an hour.
