We are very happy with the windows. We had all of our windows replaced and they are very easy to understand how to use and they are very easy to clean. So far as long as we have had these windows they have remained the same color as the day they were installed. We feel that the windows are sealed very well. From We also have decided to get a garage door from the company as well. If you give Power Home Remodeling a chance you will not regret it.
