The windows and doors are very nice. However, the installation crew was very unprofessional. First, it was difficult to communicate with them. There was only one English speaker in the entire crew. If he was busy or in his truck or running an errand, I couldn't communicate with the crew. This led to a couple misunderstandings. Also, they did not clean up after themselves. I still have shavings of glass in my yard. I had to call several times to get the crew back out to clean up large, obvious pieces of glass. My side and back yard, as well as my drive way were littered with little pieces of glass. The crew removed all of our window bars. One guard was difficult to remove, so without consulting my husband or I, they chopped the bars apart and ripped them off the window. The bars were ruined. I had to call several times to argue my case that they should be replaced. After talking with three people, Window World did decide to to refund us $200 for the damage. This did not cover the repair costs though. Our original windows and doors were covered in lead paint. I have small children and paid extra for lead containment. In my opinion, their lead containment was nominal at best. They made an effort to tape up the windows so no lead dust or paint chips would settle in the house. However, the window coverings had huge gaps in them. The rooms were very dusty. Lead dust was everywhere. So much lead paint and dust was left in my yard. My husband and I had to shovel away the top layer of soil all around our house so that our children wouldn't play in contaminated dirt. I called over and over again to get a crew out to clean it up, but it took them weeks. I was so disappointed. We paid hundreds for lead containment. Real lead containment was very important to me because of my children and pet. They had given me the impression that they knew what they were doing and were capable. I complained that they hadn't actually contained any lead, however, they refused to refund my lead containment fee. They didn't even clean it up! When they installed our windows and our doors, they damaged our house quite a bit. The window sills are scratched, some are gouged. Much of our exterior stucco is damaged where ever they worked. They installed a sliding glass door in our kitchen and broke off huge pieces of exterior stucco. They also pulled up a wall length worth of baseboard. I still don't know why they did that. I asked if they would be repairing any of the damages, and they said, "Sorry, we don't do that. Our sales rep usually neglects to tell customers." I understand that they can't be responsible for everything, but when the damage is so extreme, they should make a small effort to fix it. Again, I was very disappointed in their customer service. They ordered a wrong window and installed it anyways. They reinstalled both of my storm doors incorrectly. And, the lock on my sliding door was originally installed incorrectly. Window World did eventually fix these problems, but I was always surprised at all the mistakes they kept making. Finally, one of their crew members used my restroom and ripped the toilet lid off the seat. I don't know why. Window World did pay for the damages. I was just shocked that it happened in the first place. Overall the crew seemed untrained. I don't think they are the best at what they do. I would never use them again for anything. I was so happy when they visited for the last time. They came to reinstall a window they broke and replace some trim they forgot to order for our back door.
