The Duncan Standard: Reliable Cleaning, Responsive Service, and So Much More

Training our staff to current “best practices” or as we like to call them…”the Duncan Standard” means the team assigned to your building will have the knowledge as well as the tools and supplies to get the job done time after time. We’re not perfect mind you, but we are responsive. If something’s not right, we get it right. Ensuring you can focus your time on growing your business. Don’t worry, we got this!

In addition, we are also available to our customers for extra services such as security checks, set up of tables & chairs for events, staffing for events (frequent restroom checks, trash removal, etc.) as well as several building maintenance items. We also offer hard surface and carpet care, post construction cleaning and day porters/attendants.

Duncan & Sons’ has established long time partnerships with our vendors which enables us to offer high quality paper, liners, and soaps at great prices. We gladly pass these savings on to our customers, which allows for us to be a full service, turnkey partner leaving you more time to spend growing your business instead of shopping for supplies for your facility.
