We are proud to have earned our Diamond Certification in 2005 and every consecutive year since. In fact, SonoMarin Cleaning Services has been Diamond Certified longer than any other North Bay cleaning company. We are very pleased to have earned this prestigious award because it is based on our customers’ perceptions of our ongoing quality.
To earn Diamond Certification, our customers were randomly surveyed by the American Ratings Corporation and asked to rate our services, their willingness to use our company again and the likelihood of referring other customers to us. A score of greater than 90 on a scale of 100 is required, and most companies can’t pass this rigorous rating process.
