About Master Clean Services
Master Clean Services is an independent commercial cleaning company in San Antonio that, according to its website, has more than 30 years of experience. Its website lists recurring janitorial service, day porter service, post-construction cleanup, floor care, carpet and window cleaning and electrostatic disinfection, for offices, medical facilities, industrial sites, schools, retail and government buildings.
The website answers several buyer questions. It says office cleaning comes with no cleaning contract, so the company aims to earn the business every month. It also describes background-checked, long-term employees, ongoing safety and chemical training, and being licensed, bonded and insured. Pricing is based on the hours needed and the supplies used rather than on square footage. If an issue comes up, the website says the company returns the same day to correct it.
Master Clean Services has a 5.0 rating from 9 Google reviews. Of the 7 most recent, 3 mention communication, 2 reliability and 2 thoroughness. Ask for an estimate of the hours per visit for your facility so you can compare it with square-foot quotes.
