To answer your question, we charge by the hour. Only the time that the gardeners spent working for you will be charged.
The fee will be adjusted downward to reflect the actual time they were there.
Depending on the availability of the gardeners, it may be possible to request additional time to finish the task. A second visit will be scheduled if the team is unavailable during the first.
The size of your patio will determine how much you will pay to have it cleaned.
