Floor Leveling 101 With Ellis Screw Jacks
Here a home owner used Ellis 4x4 Screw Jacks to level the sagging floor. Access to the underside of the floor was obtained through a crawl space.
For a solid foundation, the Screw Jacks were placed on concrete piers. Then 4x4 lumber was placed inside the Screw Jacks. Next, the 4x4 Lumber was secured to a horizontal 4x6 beam using an Ellis Purlin Splicer and then jacked into position.
More Details on How to Fix Your Sagging Floors
- Simply cut your lumber to proper length:
- Measure the total shoring height (floor to beam).
- Subtract the total height of the object you will set the Ellis Screw Jack on top of from the total shoring height; for example, a piering block (like pictured above).
- Subtract 9-1/2" if you are using a 4x4 or 11" if using a 6x6 Ellis Screw Jack. This is the total distance from the bottom of the square tubing of the Screw Jack (this is where the lumber will sit inside the jack) to the base of the Screw Jack.
- Attach lumber to Screw Jack with duplex nails through holes on opposing sides of Screw Jack.
- Attach Ellis Purlin Splicer or Beam Holder in position using duplex nails along the beam where floor raising is desired. Or attach Ellis Joist Holder directly to the joist where floor leveling is desired.
- Slip 4x4 or 6x6 Lumber into Ellis Purlin Splicer / Joist Holder and attach to beam or joist using duplex nails.
- Screw Jack to height.
- Ellis Screw Jacks can be adjusted a full 6". This can be accomplished by turning the handle by hand, hitting the handle with a hammer or placing a 2x4 between the screw and handle for extra leverage when turning.
**For proper leveling, use Ellis Screw Jacks every 2'.
**If loads require more than 4,000 lbs. of lifting capacity use the Ellis Hydraulic Jack for extra lifting power.
