We had Window World install 10 windows 10 years ago and thought they did a great job at that time, and we wanted to install a few more before we sell the house. Sales rep came to the house and measured two small bedroom windows, one small bathroom window and two regular size living room windows. Since the price of them was double what we paid the first time, we went with the two small bedroom and small bathroom windows to start with and would maybe do living room later. The price of these three very small windows was over $1600, even though they advertise you can get a whole house done for under $3500. I changed my mind and wanted to get my money's worth, so called the sales rep and talked with him and said instead of bathroom window, we wanted to go with the two living room instead and the bedroom still. He said no problem, but never called to confirm. When they called and said the windows were ready, she stated what was coming and I said no, we changed the order. She had Marvin call me back, and he said he didn't remember talking to me and said he would call back after he checked his phone records to see if I called. Apparently he didn't believe me. He never called back. Meanwhile, I pulled my phone records with the date and time I spoke with him and provided him with a copy and had to call him back. He never acknowledged the mistake, but said he would offer me a "super deal" on the two I really wanted. Basically a 10% discount; not much of a deal. Their office called and said, well the deal is we have three windows that will only fit in your house ready to install, when do you want them to come. I set the appointment; on the day they were an hour late and knew we had to leave the house at a certain time. They finished in time, but later that day, our neighbor came over and informed us that the caulking was not finished. Called again, spoke with a manager this time, no apologies, just came and finished caulking. Terrible service and quality obviously awful and of course the price is not what they advertise. I would never recommend them or use them again. We also had one window from the ten-year ago installation that was compromised and clouded up in between the panes of glass. We have yet to see that replacement come. read more
