Restoring old windows is one of Restore ‘N More’s all-time favorites, and restoring the windows at the old kierch (church) ranks up there with the best. These windows are huge! Six feet wide and fourteen feet high! But it was their immense size and weight that was causing problems: The weight of all that glass caused the frames to sag which invited moisture problems and eventual rot. Rather than restore them, we faithfully reproduced new sash out of water resistant hardwood, re-installed the original old glass, and then imbedded reinforcing angle across the bottom of each upper sash to prevent any future deflection.
