10/10 Highly Recommend!

I came across Window King from an ad in a magazine. They are the dealer for Okna Windows in the tristate area. I loved the fact that they don't use any of the types of annoying ploys that bigger companies like Anderson etc uses to get your business, nor did they carry the prices of some of these bigger companies either. I got quotes from 3 other companies before settling on Window King, and I wasn't disappointed. My windows are beautiful and more importantly affordable. The service from the company is excellent, they are responsive and very helpful in terms of guiding you to the best choice for your pocket. My installation team was great!! very helpful, with minimal disruption to my home and day and cleaned up after themselves. 10/10 highly recommend!!!

Use Them Without A Doubt

Loved working with Window King and highly recommend them! I was nervous about replacing my three really old windows in my old Hoboken condo. Nick walked me through the entire process so that I felt comfortable with the windows I was choosing as well as colors, and so that I was in line with what the HOA would/ wouldn't allow. Cesar and his crew were present on install day - they were on time, courteous, fast, professional, and did an incredible job. I don't think it even took them four hours. And big thanks to Lisa who was extremely communicative regarding the timeline. My condo is now far less noisy in terms of the noise coming from the street- and MUCH warmer which is exactly what I needed. Pictured are two of my old and new windows - the black lining are the old ones and white lining is the new. If I have the good fortune to own another home, I will use Nick/Cesar/Window King without a doubt.
