“We have used Doug and Anson and his excellent team Trishelle and Hannah at Superior Maintenance for the past 2+ years.  They have kept our outside windows and common areas of our condominium building sparkling clean.  We have had many compliments on the cleanliness of the building from owners and visitors alike.  The cleaning team clearly takes pride in their work and are easy to work with and very approachable.  Doug will work with you to meet all your cleaning needs and arrange for times that work for you.  We are very happy with the services provided and know you will be too.”
