We initially hired Cornerstone Cleaning & Custodial for a trial cleaning. They came after-hours as we requested and the cleaning job they did was very efficient and thorough. We were impressed and hired them on the spot. They have continued to do a very professional job for us for nearly a year now; unlike other companies we worked with who would tend to do a poorer job as time went on, Cornerstone has held their standard high over time. We recommend them highly, they are amazing!

The crew is very professional, friendly and do a good job of cleaning. I would recommend Cornerstone to anyone inquiring about a cleaning company.

We've been using Cornerstone since 2017 and have always been extremely happy. Jeannie's attention to detail, professionalism and dedication have been a godsend for our 17,000 sq ft building and 50+ residents - especially during the pandemic. I'm very pleased to recommend her to anyone looking for an honest, reliable service. JVN

We engaged Cornerstone Cleaning & Custodial Services for regular care of our office suite in Fort Collins. Jeannie promptly provided a written quote, several references, and all the documentation required by our corporate office regarding insurance. She arranged for the crew to provide service during off hours so our business wasn’t impacted and worked with us to address any non-standard tasks. They always provided top-notch service and checked in regularly to make sure we were satisfied with their service. When we stopped using the office for a brief time due to employee travel schedules, they arranged to suspend service for that time so that we weren’t paying for service that wasn’t really needed. All invoices were submitted in a timely fashion and were accurate and complete. Cornerstone provided the services we needed at a competitive rate and were always a pleasure to work with. I wouldn’t hesitate to engage them again!
