Sterk Cleaning technicians are the best in the business. Low employee turn over is key in our business as it provides our customers with an experienced technician that they can rely on for years to come. New technicians work under the careful guidance and instruction of a senior technician for two months or more before they are certified to work independently. Sterk Cleaning technicians are expected to arrive at your house or facilities on time, dressed cleanly and neatly, and are able to communicate clearly and completely about what they will be doing, and to discuss with you any concerns you might have about the process. They can also make recommendations or suggestions about a host of cleaning issues at your request.
