"The installers came on time and were totally professional, experienced and worked continuously until the job was done. The triple pane windows are fabulous because compared to our old two pane faulty windows, not only are they solid and beautiful with no wind blowing through, but also the nearby road noise is greatly reduced. We needed to use plastic film to insulate the old windows and when the wind blew the plastic would billow like sails! The new windows make our condo seem like a true home."

"In the past, I have cleaned my own windows. This is the first time I have used a professional window cleaner, and I was a little nervous about how the windows would turn out because Iâ  m pretty fussy. I am so pleased with Delâ  s Window Cleaning! They were easy to reach, responsive, punctual, professional, and they did a great job. Will definitely use them again. HIGHLY RECOMMEND."

"They did a great job. We have a lot of windows and storm windows and they were very thorough. The entire job took most of the day and Kevin's crew stayed at it until it was all done. When we walked through afterwards, Kevin had the crew make corrections and adjustments immediatelly. I will use All Clean again."
