Family owned and operated. Tri Maids understand the needs of Southern California home owners - we live here too. For 25 years, we have perfected our cleaning techniques by listening to our clients. We have taken the house cleaning service to a new level with the introduction of our Probiotic cleaners, which literally remove germs and allergens at the microscopic level. Scientifically proven at Hospitals and Universities, there has never been anything like this. Your home will not only look and smell squeaky-clean; it will re-define what clean should be.
