Great job!
Best of the Best
All around best service of window cleaners! Switched to DeMarks and now windows are cleaned to perfection every 6 months!
Sparkling Clean
The DeMark Window crew did a wonderful job with cleaning the windows of my condo. They were courteous and efficient. No more spending a whole day myself struggling with ladders and Windex. I plan to have them back every Spring!
Highly Recommended!
DeMark's are extremely helpful window washers!!! Highly recommended for your home!! We were able to set up an appointment on a Saturday to work with my family's schedule, the company was very flexible with our needs. I couldn't believe how clean our windows became with ...the interior and exterior cleaning! The workers even removed the storms and screens; the windows have not been that clean since we first bought them! I recommend DeMarks for their great customer service and quality of work.
