"Hi. The person that came to replace my window was very professional first got me the estimate then in 2 days came to replace my window after ordering. Then call me to let me he was coming. Process was fast and efficient and price very economic. I call other places they won’t answer and leave message and after a week they call me when my window was changed already. I recommend Duraglass their job was efficient and fast."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"You can probably get the work done for less money, but Doug and his crew are high class professionals. Courteous, prompt, competent and efficient, they installed my air conditioner according to the buildings requirements and in a way that added to the aesthetic of the room as an in window air conditioner rarely does. I was very pleased with the work and would use Doug again."

"Window King is one of the top rated window contractors in my area, so I scheduled an appointment with them, as well as with the other two top rated companies. I met with Window King first, and immediately liked their punctuality and professionalism. Nick, the owner, is very personable. Anyone would appreciate his no pressure sales approach. I know I did. Even after being in the business for so many years, he understands that most of us know nothing about windows and so he takes his time discussing our wants and needs, his products, and by the end of the appointment he provides a thoughtful recommendation and quote. Note, all this is done without overwhelming us with too many facts and numbers. Yes, he mentioned the values and stood behind the quality of his products when compared to the BIG NAME BRAND windows, but he preferred we take the fact sheets provided and do our own comparisons (which I was going to do anyway). I'm a skeptic so I was going to do my own comparisons. After meeting with the other top rated contractors, I decided to go with Window King for the following reasons: 1) OKNA 500 series window's ratings are equal to or better than almost any replacement double hung window out there. 2) Window King's quote was cheaper and included more work than his competition, even when comparing the exact window. 3) OKNA manufacturer Lifetime Warranty. 4) Years in business. 5) Work isn't subcontracted. I was not disappointed with the installation. In fact, I was very happy. The crew was punctual, professional, courteous, and they finished in 2 days which was amazing considering the scope of the project. Their attention to detail was second to none. The windows were installed properly, they cleaned up after themselves, and made sure we understood how to operate the windows before leaving. During the install, Nick even stopped in to make sure we were satisfied. I'm planning on installing a bow window in my den by next year, so I'll be using them again without a doubt. I will not hesitate recommending them to friends and family."

"Aldo did a great job I found him on the internet and really could not be happier he was neat and moved a wall to make a room larger for a city inspection. He also put down luxury vinyl flooring at the same time. I have 6 small buildings in Brooklyn and will without a doubt use him again Thank you Aldo"
