Your Expectations. Exceeded.

Here are a few things our customers and our service partners have said about us over the last 30 years.


Dear John,

I just wanted to say that many years ago, around the time John first started out in business, my husband and I decided we could use a second job. We had just bought a new house and needed a little extra money.   We were lucky to get hired for office cleaning by John. Some people might wonder why I would say lucky. We worked all day and then went to our second job. We were treated well by John, he was always fair with us, didn’t follow us around, he knew we could get the job done and he let us do it. He recognized us after we worked for more than a year and also after that. John is a good Christian man who treats his employees with fairness and respect. It’s one job that I loved going to. Thank you John for being a great employer.

ServiceMaster by Pletz,

I just wanted to say what a great job Marilyn Donta, Karen, and Tom did cleaning our office. I was trying to clean in between doing the receptionist job, but it sure didn’t look anywhere near as nice as when Marilyn, Karen, Tom cleaned the office. Marilyn is thorough, personable and a great asset to your company. We are glad that we contacted your company.

Thank you very much,

Catherine Heine

Mr. John Pletz ServiceMaster by Pletz Crystal Lake, IL:

Dear John,
I stopped by the office this morning to check on the floors you had cleaned and waxed for us. As usual, everything looks top notch. I noticed by the card left that it was Dave McBean who did the work.

I have never been disappointed with any of the service people you have sent us, but I have always been especially pleased with Dave`s results. The floors look clean, evenly waxed and shiny. I can also tell that he takes care around the dental chairs and cabinetry. The office is always left clean and orderly-except for the improved look of the floors, I can hardly tell anyone was in here over the weekend! Thanks again for your good service.

Sincerely, Michael T. Reilly

Centro / Northbrook, IL

Dear John,

On behalf of Centro Properties Group, I would like to take this opportunity to express my appreciation for outstanding service and professionalism over the years we have received from ServiceMaster Commercial Cleaning by Pletz, Inc. Your company has always demonstrated these qualities that have been a hallmark of your own personal philosophy, and it is clear nothing has changed. It seems like yesterday (10 years) when you and I worked together on many challenging projects for Centro. Your business ethic was then, as it is now, serving cutomers needs. In the fast paced world we live in today, sometimes the “personal touch” is too often overlooked or worse, taken for granted. I am please to say ServiceMaster by Pletz has never disappointed Centro Properties Group or me. From you field superintendents, to your on site staff representing your company, the experience was always positive. I look forward to continuing to build our relationship in the future,

The Summers Academy of Dance – Crystal Lake, IL

Dear Customer Service,

My husband and I have had ServiceMaster do an annual “Heavy Cleaning” at our Dance Studio in Crystal Lake for the past 4 years. Their usual stripping and “triple waxing” the floors before we begin the fall semester at our Academy has been a mainstay. We have always been very happy with their service. As our business has grown we came to realize that we needed a professional weekly cleaning, and so we called ServiceMaster. We have has terrific personal contacts through Dave who came in and didt the orginal assessment of the areas that had to be cleaned, and assured us that ServiceMaster could take care of our cleaning issues, Marilyn stops by to see if “all is well” and asks if we are happy with the service and if she can help with any other cleaning options. We cannot begin to say how happy we are that ServiceMaster was able to schedule around our “open 7 days a week” to find a time, and a price that would work for all of us. The best part is I (Vicki) get to go to work on Monday morning and know that the studio will be ready for a full week of Moms and Dancers with Siblings and Grandmas and that The Summers Academy of Dance will make a “clean” first impression-that’s very important!. Gary and I just felt that you should know how happy we are that ServiceMaster is taking care of keeping our facilities ready for dance! All of the staff that we have talked to have been great! Thanks!

Dear ServiceMaster:

This letter is to commend Eva and the wonderful job she has done with our office. We had left your company because of financial constraints and returned to you because we were unhappy with the cleaning by your replacements. It’s true that old saying “you get what you pay for”. Anyways, we couldn’t be happier, especially when our members comment on how great our office looks. We even had the owner of Janus Janitorial mention the improved appearance of our branch. Keep up the good work. Thanks again,

Gail Wieland,
Office Manager
