Question
Hi Bruce,

I need to remove a window from a cinder block extension, the window was installed with the flange into the slots of the cinder block. and I believe they pored concrete into the holes of the block afterward, do you have any suggestions on what might be the easiest way to remove the window.. I already removed one, it took 5 hours to break away all the cement..Is there another way? Thanks Chris

Answer
Hi Chris, If destroying the window isn't an issue then I would take a grinder with a metal cutting blade and cut the flange off, remove the window and then just pry the remaining flange from the masonry.  A concrete cut saw will work also with a metal blade in it.  If for some reason you are trying to save the window then you can use the concrete saw with a concrete blade in it and try to cut the masonry from around the flange.  Most tool rental places have concrete saws for rent either electric or gas powered. As far as grinders go, I keep a 4 1/2" grinder around for projects like this.  They cost maybe 40 bucks and can be used for cutting all types of material including masonry and ceramic tile.  I hope this information helps feel free to write again regarding this or other matters, sincerely bruce e johnson..bejohnsonconsulting.com
