I highly recommend Mr. Rogers Windows. They are extremely professional, courteous, prompt and reliable. And they stand behind their products. I was unhappy with a miter joint on one of my windows and they replaced it--no questions asked. They wore little hospital booties on their feet while they were inside my home to protect my carpet. When Mr. Rogers says they role out the red carpet...he means it. You may pay a bit more, but it was worth it to me. I have piece of mind knowing I got a great product and a great installation.
