The Truth About Windows

5 things you should know about the window business

The Best Rated Window Company in Indianapolis

Our home built in the late 80’s still has its original windows. Our living room window which consisted of three double-hung windows faced west and was extremely drafty and visually unappealing. We hired the Window Source of Indianapolis to replace the three windows with one large picture window and added grids. The new window is amazing! Jason showed us many options for the opening and we are so happy with the picture window. The three windows we had prior seemed clunky in that space. It now feels more open. It is also clearer since there are no screens. The wood trim on the outside was rotting and they replaced it and the color matches perfectly! The installation process was seamless. The crew was easy to work with, professional and left no mess behind. Start to finish, it was a great experience!
"The installation process was seamless."
