What Our Customers Are Saying
I live in a condo complex and had DeMark's clean my windows inside and out and they did an incredible job! The young men that did the work were thorough, neat and personable. And when my building was power washed by mistake causing streaking on all the windows, Alan had someone come right out and rewash the outside of the windows at no cost to me. I will definitely use them in the future and highly recommend them to anyone else.
