We can certainly assist with this.
Visit www.SweepSouth.com/booking to start a booking - our page is geared towards general home cleaning. What you can do is select 0 bedrooms and 1 bathroom (the minimum) and then select 'Interior Windows'.
The minimum booking time is 3 hours, so you're welcome to adjust the time as your feel is required.
You will then also need to chat to your SweepStar and let her know that she is only required to complete window cleaning.
*Please note that our SweepStars are only insured to clean interior windows and may not stand on any ladders or steps to complete this task.
