Mari’s Professional Home Watch & Cleaning Services of Peoria, Arizona, has earned second-year accreditation from the NHWA

In 1994, Owner Mari Williams was working in the office on Gainey Ranch, when she was approached by some absentee homeowners who wanted her to watch their homes while they were away. There was some major roof leaking, and Mari’s services saved them a lot of money and aggravation. As word spread about Mari’s great services, her business grew, and Mari currently manages over 85 homes in Scottsdale and Peoria.

As a young child, Mari’s family owned a cabin. She recalls that when they arrived, she wanted to just go out and play; instead, she had to assist her mother in cleaning the cabin. This process was done again just prior to leaving. Mari’s memories sparked the start-up of the cleaning business. She wanted the homeowners to arrive at their vacation home and just be able to “go play,” and when they were ready to leave . . . just leave.

As the word got out about Mari’s excellent cleaning services, the business began to grow once again. Today, Mari is pleased to provide cleaning services to over 425 customers across the Peoria, Glendale, Phoenix, and Scottsdale areas.

Mari has always wanted to give back, so she has partnered with Cleaning for a Reason, where she provides free house cleaning for men, women, and children undergoing cancer treatment. (For more information, please visit

Mari’s husband, Scott, has been involved in the family business on a part-time basis for approximately 20 years. After his retirement from Gainey Ranch’s community association as the Director of Maintenance for 38 years, Scott has now come onboard full-time. He brings a wealth of knowledge, along with years of experience in the building and landscape maintenance industry, including strong administrative and public relations skills. Scott has a full understanding of community associations, compliance processes, and overall operations. His years of assisting Gainey Ranch homeowners with an array of interior challenges is an invaluable asset to their business. Scott has earned the designation of Certified Home Watch Professional from the NHWA, making him one of the elite Home Watch providers in the industry. The CHWP designation shows his commitment to providing excellent service to his clients.

It was a pleasure to see Mari at the NHWA’s 2022 North American Conference last October.
