In Reply to: Enlarging basement window in masonry Posted by: Chris Duncan on June 15, 1999 at 22:58:16:

: Roughly-finished, below-ground basement with 7' ceilings currently has drafty, rusting 15" high x 33" wide windows right at top of walls. Can I enlarge opening in masonry and dig lower in outside window well to install larger windows? What do I need to get through 8" thick 1959 masonry foundation? Can I do it myself or does this call for professional help? Do I run risks of water problems (minimal dampness currently)? Other possible problems? I haven't checked books yet -- after all, it's 1999 and we've got the web -- but would get one if recommended. Thanks,

It is really a simple project to enlarge basement windows. I would say that the biggest problem you will have is cutting the old masonry out. Your letter does not say what the foundation is made of. Once the opening is enlarged to the size wanted ensure that the header or floor joist will span the new window. You may have to add to the header if you go much wider. As for the window wells if you are worried about water dig them deeper and tie into your drain tile around the footing of the basement with a vertical drain tile (4" pvc works well) there are screens for the top. Backfill to within one foot of the bottom of the window with the soil removed and then at least 4" of crushed rock.
