I was very satisfied with Feldco the windows I purchased were of great quality I purchased the 2nd floor first and later purchased the 1st floor and will purchase the remaing 6 windows this Spring since I am on a budget and do a little a time The men putting in the windows were very polite they removed the old windows and took them and put the new ones in and they fit like a glove they came previously to measure when they were done there was no evidence that they were there only the fact that the windows looked great I was very satisfied and plan to use them for the last of the windows that need to be replaced
