Irwindale Windows Co. is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Looking for windows? Look no further! The only reason that I gave Irwindale Windows Co. 5 stars is because that is the highest rating that I could give. Jimmy Maa is the man! Very low keyed in his presentation with absolutely no pressure. In fact he originally showed me lower priced windows than what I ended up buying. He did not try to upsell and showed me windows that he figured were within my budget. I'm the one who asked about the higher end windows. He gave me the absolute rock bottom price (no time limit on the price) on the Milgard Tuscany windows which included installation (Home Depot was about $150 higher per window not including installation) and told me to call if I decided to go with him. I originally did not want the Milgard windows since I had been told that they did not lock in the slightly open position. When I asked Jimmy about this he demonstrated on his sample window that they did. Why would I buy windows from another company whose representatives don't even know the features of the product that they are trying to sell? I did call Jimmy a few days later and he came down to finalize the order. By the way, he only asked for a very small deposit to get the ball rolling. When the installer arrived he was on time, courteous, and professional in his installation. I was surprised at his attention to detail and he did not leave a mess. The windows look beautiful and I couldn't be happier. I could only afford to install the three windows that were broken, but when the time comes to install the others I am only making one phone call--Jimmy Maa at Irwindale Windows Co!

Rated 5 out of 5 by from OUTSTANDING SERVICE AND WORK Jimmy Maa and his crew installed the Milgard Tuscany series windows in my condo in El Monte, Ca. on April 10 and 11. Being a fussy old man, I have to say that I am very impressed with the excellent job they did. I have never seen a crew of workers in the construction business, that did a neater or cleaner job. They do fantastic work and leave absolutely no mess to be cleaned up by the owner of the project. I would highly recommend them and their wonderful product. I found them to have the best price on this product and believe me, I am a shopper. As you can see, I am a very happy customer.
