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." - Property Manager, Greenway Plaza Office Park

"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." - Gailrach Realty Company LLC
