Green Maids Canada ordinarily guarantees a specific day for your house 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 for our arrival. However, if you contact us on the day of your service, we will be glad to estimate our time of arrival. If you need a specific time guarantee, feel free to discuss this with your local office. Within reason, we will do our best to reach a mutually agreeable solution.
