Supporting Floor Joist Above Egress Window

Set a hydraulic jack and post under the beam and jack up the joists about 1 8 in.

Supporting floor joist above egress window. A day until they re level. When a door is being used to meet the egress requirements it must be either a side hinged door or a slider. Using a scrap piece of wood and your hammer bang each side into place so it is supporting the header. Jacking them up too fast may cause cracks in the walls and floors overhead.

Once it is in place screw it into the floor joist above it. Since our egress basement window was in a wall perpendicular to the floor joists in a weight bearing wall we built a temporary support wall photo 2 to carry the weight before cutting out the window opening and putting in the header. I would also be concerned about the lack of a header above the window where one floor joist bears as there is nothing to support the sill plate there. Install the temporary header close to the wall but leave enough room 2 or 3 feet should be enough to work.

Nailing two 2x4s together will work to span about three joists unless the sag is under a weight bearing wall. Cut the pressure treated 2 10 to fit the depth of the wall then cut them to length for the sides of the frame so they are a tight fit. The sill plate could easily sag and bow bind the window. How old is the house and is there an emergency egress window from the basement or a walkout door.

Sawing concrete creates an incredible dust cloud.
