Jacking up a wall off platform frame to replace subfloor
Posted: Fri Aug 19, 2011 11:31 pm
Hello All,
We have suffered a lengthy failure of our water heater (due to no drain or pan and linoleum stretching far into the bedroom and closet under the carpet) to the point where our sub-floor has given way all the way through the exterior wall to the platform frame bottom joist. I can chip away the soaked MDF all the way through to where it reaches the compression of the frame, but I would like to chip out the area of compression to be able to put the new sub-floor in all the way.
Yes there is extensive mold and I am dealing with it with all the common precautions as well as using Shockwave on the lumber.
I realize that this is really not a DIY project but I have to exhaust my own options as much as possible at least in demolition before I get a contractor in.
What would be the best way to separate the platform frame sub-floor from the exterior wall? It runs at least 14 feet, from the laundry area to nearly the end of the closet. I am thinking two steel shores (screw type) to use either on both ends of the entire span, or just do one piece at a time starting in the center. Also was considering saving money by using bottle jacks since I will never be in danger by them losing air from one day to the next. I would think I only need the slightest of margins to slip the new subfloor under the frame, maybe a half inch.
What do you all think or recommend?
