"Zen windows just replaced 57 windows in my 22-year old house and did a fantastic job. I did my research and had 4 different estimates. They were very competitive and used a solid product (ProVia Windows) , not to mention and lifetime warranty on windows and labor that is transferrable. Hopefully, I will never have to use the warranty. Here is why I recommend them: 1.Easy estimate/ quote and negotiations. David, the sales guy, was very responsive to my questions even at 9pm at night. He also arrived on time and came back to answer more questions. 2. Product (ProVia Endure Window) seems like a solid and good quality product. ProVia is known for their doors and recently moved into the windows around 2010. We go the Endure brand- great energy efficiency with u-factor .27 and solar heat gain coefficient at 0.19. 3. Payment due at the END of installation. No down payment needed. They accept payment plans. Took about 10 weeks for windows to arrive 4. The Measurement guy (I think his name is Michael), very professional and arrived on time-had to come twice as I added a last minute window. - I was told the last window would arrive late and that installation would occur at a different time, but they all arrived on time. 5. They had 2 Crews working and they were great. Because of all the demo, my house looked like a war zone. But they were very respectful and cleaned after themselves. It took 2.5 days. They took down all the window treatments/ blinds, tore down the existing windows, replaced them all. We had some dry rot on one window and they replaced it (charged me for materials and time). They DO NOT do any spackling or painting FYI. (If you know you have a problem with a leaking window, MAKE SURE you check the wood prior to having them put the new windows up. - That would be the only concern that I had. I missed looking at the window sill prior to them replacing them but they said the wood was not dry rotted like the other one. They said not to worry though b/c of the warranty. Personally, I don't want to have to deal with the warranty but that did give me some piece of mind.) They cleaned all the windows and checked each window and put the curtains/ blinds back that I wanted to keep I also had 2 screens that were damaged and one lock that was not working. They fixed the screens, and someone will come tomorrow to fix the lock (one week later) 6. Job walk through and instructions on how to use the windows were done with Luis (supervisor) and again with James the lead foreman. James also called every night to check on how things were going. I also liked that we discussed final payment before it was due. OVERALL, a solid company with a good product. Of note, soon after the job was done, we had temps in the 80-90s and did not need to turn on our AC until the 3rd day. the windows were able to keep the house insulated. Normally we would have had to put the AC on the first day it in the 80s. Happy so far!"
