MahlerClean is built on a culture of personal service and quality.
We attribute our success in the cleaning industry to the following key factors:

Customer Focus

We regularly audit our work and solicit feedback on our services to ensure customer satisfaction. If it’s not right, we will make it right.


Timely and transparent communication is key to successful long-term relationships. Our team is available 24/7 to address the needs of our clients and our employees.


Engaged in industry trends, we are committed to being ahead of the curve when it comes to using innovative products, equipment and processes in the delivery of our services.


Solving services issues and overcoming challenges is in our DNA. Every building and every person is different. Our team uses a broad range of knowledge gained from years of experience to identify issues and provide solutions.

Personal Development

We promise to provide ongoing training and development to our service team to offer opportunities for career advancement.

Local Roots

As Wisconsin’s largest locally owned and operated building services contractor, we have thoughtfully expanded from our home base in Milwaukee.

  • Open Communication

    We recognize effective and transparent communication builds relationships and results. In addition to in-person site audits, our management team uses smart phone technology to allow efficient communication. Virtual or onsite communication portals serve as a place for both parties to leave productive messages. A live answering service, during non-business hours, offers 24-hour client and employee access.

    A Great Team

    Through a culture of proactive service and a positive attitude, our MahlerClean team maintains the highest customer service standards in the industry. All employees attend a classroom training session and receive on-the-job training. Periodic checks by our educators and managers help evaluate training and provide enhancements as needed. In an industry accustomed to very high turnover rates, ours is less than half the industry’s average. For several years, we’ve been nominated as a Journal Sentinel Top Work Place by our employees, which gives us a competitive edge in recruiting new team members.

    Commitment to Quality

    We expect our work to speak for itself, and we maintain an active Quality Assurance Plan (QAP) to ensure that it does. Our plan includes:

    • Daytime tours (scheduled or unscheduled) by our District Managers who use industry leading inspection software to provide measurable reporting on our performance.
    • Unscheduled inspection by members of our management team to observe crews and inspect their work habits.
    • “Fresh Eyes” visits by members of our senior management team who may not routinely visit your facility.
    • Housekeeping committees for larger facilities, to make sure all parties have similar expectations, and these are being met consistently.
    • Semi-annual, web-based client satisfaction surveys.

    More on Our Services

    Commitment to Safety and Security

    We take your facility’s security seriously and are committed to ethical and legal hiring practices, beginning with our pre-employment screening process. It includes a review of criminal records history, previous employment verifications, and Everify employment eligibility. We work with many clients that require more extensive screening requirements, and we are able to customize and adapt to these procedures accordingly.

    All service representatives are required to wear a MahlerClean uniform and carry a company issued photo ID badge. They are trained to follow our clients' building security procedures, including setting security systems, turning off lights, and properly securing the facility at the conclusion of service.

    Keeping our employees safe and minimizing opportunities for lost time as a result of workplace injuries is important in delivering consistent service. We educate and invest in training our service team on product and equipment safety, use of PPE in the delivery of our services, as well as other hazards. We comply with all required worksite safety requirements, including onsite copies of all Safety Data Sheets at each facility.

    Accidents may occasionally occur during our delivery of service, but rest assured that all of our representatives are properly insured against breakage, damage, and missing property. Proof of coverage will be provided at the start of service.
