We purchased our 26 windows and one sliding glass door from Castle Windows four and a half years ago. We couldn't be happier with that purchase. We researched the market and Castle was the best fit for our needs. We liked that Castle had a reputation for quality and service.
The salesman was friendly and courteous and we believe we got the best value for our money. We had a service rep come out once in the first year to make a minor adjustment and have had no problems since.
I think that some of the negative comments toward Castle Windows on this site are are exaggerated somewhat. We would recommend Castle Windows to anyone considering having replacement windows installed by a company with a reputation for quality and service and the best warranty in the industry.
