If I could give them less stars, I would. Had groupon coupon. They don't return phone calls. First red flag. They don't remember that they are to be at your house at a certain time because ""oh here it is, it is written on the wrong page"". No apology! But they offer to come out on a second attempt. No one shows up yet again and no one bothers to call. They simply no-show after you rushed home to be there in time for them. Two hours later they show up and say your windows are not small enough, so windows will count as two! It's not in the fine print for first floor windows! Crazy way to run a business.
