Good product, bad installation
We had a dozen windows installed last year. The salesman told us installation would be done by 6 to 7 guys - a rolling progression. Instead we got 2 guys who started at 8:00am, a third who arrived at 3:00pm and they didn't finish until 8:00 pm. We had to provide a taller ladder and a spotlight since they could no longer see what they were doing after sunset! One of the windows leaked in the rain so they came out (4 days later) to recaulk. That same window still leaks rain 2 months later. They massacred our indoor window frames and it cost us $300 for drywall repair & painting with separate contractors. We need more windows this year but will go elsewhere. Their prices are good and the product definitely is more efficient in keeping out cold & heat. If the install was better, they'd be great. What a shame.
