Mary Ann Budzban, Director, Carbondale New School

“As the director of Carbondale New School, I am responsible for the health and safety of 65 wonderful elementary and middle school students.  When we were recently confronted with a serious air-quality predicament in the school, your professional services were invaluable for solving the problem.  Your prompt response helped us to quickly regain a clean and healthy environment.  We were reassured by your considerable knowledge and experience, and your dedication to the clean-up effort went the extra mile. I would highly recommend your services, without reservation, to anyone confronted with an air-quality problem.  It was a pleasure working with you”.

“I write with great excitement to recommend the services of GPS. My husband and I own a few rental properties in southern Illinois. We work in Washington, DC and GPS handles our on-site property management, maintaining the properties while we’re away. GPS is not only reliable and committed to quality service, they have a desire for innovation that keeps us confident that we’re working with the best! Their honest, straight forward approach to any problem we’ve had, including mold removal, has allowed us considerable peace of mind. I am sure that your experience with GPS’ services will be of superior quality. I have no question in my mind that your smile will be as big as mine when recommending their services in the future! We’ve used GPS’ services for almost 5 years and hope to continue to do so for many more”

“GPS was fantastic. They worked well with my schedule, and did a fantastic job draining my basement and mold proofing it. The price was well under any other estimates I received and they finished the job quickly and efficiently. I would highly recommend their services for any basement cleaning or sealing project. A+ work”.
