After researching several other companies online through Google, Yelp and Angie's List and reading all of the bad reviews on local companies in my area, I came across Zen Windows. Other companies require a sales person to come to your home but not Zen Windows. I was a little skeptical at first because I wondered how they could give me an accurate price quote without seeing my home but they had set prices per window for the style we wanted. I requested a quote online and was contacted by Andrew. We had a brief 5 minute conversation over the phone so he could get an idea of what we wanted, including how many windows needed, and had a quote sent to me shortly after. There was no pressure, no pushy sales tactics, no hassle. Andrew advised me to just let him know if we'd like to proceed after reviewing the quote. We needed 18 windows installed and he gave us a very fair, reasonable price. Our windows were ready within a few weeks and installation was set for shortly after. The installation team (3 guys) arrived on time and started working right away. I was originally told it would probably take 2 days to install all of our windows but they had them all done in 7 hours!! They never even stopped to take a break. We were really impressed. They were friendly, funny and talked to us all afternoon. It made having strangers in our home a lot more comfortable. Before leaving, they showed us how to operate the windows. I love the fact that our windows can be flipped down and cleaned from inside since we have a 2 story home. I definitely recommend Zen Windows Pittsburgh to anyone and everyone looking for quality windows at a reasonable price. After our exceptional service, I wouldn't go anywhere else! Thanks Zen Windows!!
