GMG Services

GMG Services provides holistic facilities management services that are far superior to any other. Here are some services that we provide

Commercial Cleaning

Whether it’s a school, a senior home or a commercial space, we will make your facility shine.

Carpet Cleaning & Floors

GMG provides commercial grade carpet cleaning and stripping, sealing and re waxing floors.

Window and Screen Cleaning

Interior and exterior window cleaning by GMC creates streak free windows and screens which let the sun shine through.

Maintenance Services

Cleaning your facility is just a part of the holistic service we provide. From minor electrical, plumbing and repair work, to flooring, painting, walls and doors – we help maintain your facility so you don’t have to waste your time shopping around for dozens of vendors.

Covid-19 Disinfecting Service

Disinfection is only effective on clean surfaces, as dirt can protect viruses and bacteria. We follow by manually disinfecting frequently touched areas, or use a ULV fogging machine to disinfect the entire space and all surfaces.

What Our Clients
Say About Us

I have been nothing short of impressed by this company ever since they started cleaning for us. They are professional and thorough, and our place has never looked so good. Our last cleaners would come to clean, and then I would hear the complaints afterwards. What I hear now is, “This place has never looked so good!” Walter and his professional top quality cleaning crew have really made the difference in our day to day ops at Brunk. Best decision we’ve made to hire them!


Linda Bartlett

Walter is a man of his word! He prides himself in doing the tough jobs and doing them right. He and his team responded to our needs in a timely manner with great professionalism. When expectations were not met with the initial work, Walter made it right. You can trust this guy to do what he says he is going to do! Thank you, Gheller Management Group!

Magdy Rabeaa

We have been using GMG Cleaning Services for two years now. The difference between Walter’s team and our previous cleaning company is tremendous and we were able to notice the change day 1. His team is punctual, very thorough, and they continue to go above and beyond our expectations. During this pandemic, GMG makes sure that we have all the necessary supplies and that all high traffic areas receives extra attention to ensure the safety of our working areas. Thank you, Walter and GMG Services for everything you do!!!


Arthur Farber

Walter and Liset are in regular contact with us about the status of cleaning, and what is/not being done. They respond quickly, and although we have some challenges, they continue to try to improve through communication and by working directly with their crew and our staff.


Sheila Przesmicki

I have been using Walter and his crew for a few years now and he has always provided great customer service. He has been so easy to work with and is always quick to respond to any concerns or questions you have. The job is well done and any time we have had special requests or changes in schedule they are always so accommodating.
