"Preferred Capitol Cleaning did an amazing job cleaning a 100,000 SF Sr Living Building for me. They attended meetings, were prompt, and adjusted manpower to meet the demands of the project. Ana and her team were responsive and accommodating and I would highly recommend them for your cleaning needs."

“The new Marriott Headquarters was Preferred’s first opportunity with Hensel Phelps. From the beginning, we got a sense of partnership and a high level of service from their Owners and field supervisors. Our first experience with Preferred was great from beginning to end and look forward to working with them in the future”

"Over the last several years I have relied on Ana, Illissa, and their team at Preferred Capitol Cleaning to ensure my office build-out projects received a thorough final cleaning service in order to properly turnover beautiful spaces to our clients. Their team has been able to exceed all expectations project after project. The whole team’s attention to detail from the pre-work site visits to the last day of cleaning is what sets them above everyone else. We often spend months of construction working to deliver a successful project, but it’s the work at the very end that gives the initial impressions to the tenants who will be occupying the spaces. Without the above and beyond efforts from the whole Preferred Capitol Cleaning team on my projects, the turnovers to our collective clients would not be nearly as successful and gratifying. On top of that all, they help make our team’s jobs that much easier and I am grateful."
