E-Z Clean ordinarily guarantees a specific day for your cleaning but not a specific time. Due to our flexible and ever-changing schedule, we are unable to commit to a specific time of day arrival unless you are the first appointment of the day. However, if you contact us on the day of your scheduled service, we will be glad to estimate our arrival time. If you need a specific time guarantee, feel free to discuss this with us in advance or in the Special Instructions area of our online booking form and, within reason, we will do our best to reach a mutually agreeable solution.
