I went to Lowes to purchase and have a cliding glass patio door installed. The door was priced about right and the estimate including install was about $435. but somehow I ended up with a bill for over $1000. I called the store manager and have not heard back. It appears that I was charged almost $700 for an install that was standard and took the two men who came under two hours to complete the replacement. I saw their invoice and it gave them $125 for their work installing the door. Beware of using lowes. I found this prohibitively expensively and would not use them again. read full review »
