Our Happy Clients

"Since we started using Manantial cleaning services two years ago, we noticed a considerable difference in the quality of the cleaning services. Any task is done right, with great attention to detail.

In addition to improved Tenants' satisfaction, it freed our personnel, as we don’t need to spend time reacting to the tenants' cleaning complaints.

I am very impressed by the pride that Katherine and her team take in the work and have confidence that her team will do the right job every time." - Michael I., Property Manager

"We have been using Manantial Cleaning Services to clean our offices at The Bethpage Professional Building for a year and couldn't be happier with their performance. They do an excellent job, are very thorough, and honest. Unlike most cleaning companies who tell you that they will get the job done properly but never do, Manantial actually goes above and beyond to make sure the job is done correctly." - Joshua W. - Building Manager

"Since the first call with Manantial Cleaning Services, they have been nothing but professional. Katherine meet me at my office early one morning and spent a great deal of time with me going over what I wanted in the office cleaning. She came the following Saturday with a crew of 8 and spent the entire day cleaning and sanitizing the office. Her suggestions for new items in the office were fantastic. My whole executive staff is beyond happy with the results. Our weekly cleanings have been done with the same type of attention to detail as the deep cleaning was. I speak for everyone here, this company is wonderful and highly recommended." - Lisa G., Office Manager

First thing this morning Al and I were approached by a customer to discuss the condition of the restrooms at Stirling.  He took the time to seek us out in order to thank us for the incredible work being done to keep our restrooms in top shape.  Work you and your staff have done for us. 

 There is no question as to the value of the investment.  Thank you again for the wonderful service and attention to detail. ” - Sean, General Manager
