I tried 2 separate times in 2 different years to buy windows and siding here. The siding they flat out refused because they said there wasn't enough money in it for them since I wasn't doing the whole house. They wouldn't honor the sale price of the windows they advertised in an ad. They added surcharges that brought the price higher than Home Depot and Lowes. If you work, you must take the day off because they won't give you an appointment for measuring. It can be any time during the day, whenever they get to you. Unified is a failure of a business and I'm done with them.
