If a floor is not level, it can be a nuisance to walk on and if the floor is extremely out of level, it can present a safety hazard. A slanted floor can also make windows and doors stick or become difficult to operate. It can even cause the area over a window or door to crack. By repairing a floor that is not level, homeowners find it easier to navigate the area and use the doors and windows.
You will need:
• Downspout diverters
• Floor jack
• Wood block
• Wooden support posts
• Galvanized sheet metal connectors
• 8-penny nails
• Tape measure
• Circular saw
Step 1: Stabilize the moisture content in soil near the foundation of the home. Grade the soil so water sheds away from the foundation. Control the landscaping irrigation system to prevent excessive moisture. Install downspouts and gutters and keep these clean. Add an underground drainage system and downspout diverters to channel rainwater away from the foundation. It may between a few months and a year to achieve stabilization of moisture content.
Step 2: If this process does not level the floor or is not effective enough, new support posts must be installed under the floor. Begin by placing a floor jack directly under a support beam located at a high spot on the floor. Put the jack on top of the wood block and locate it a couple feet from the pier.
Step 3: Jack up the slanted floor until it is high enough to remove the support post. Use the sledgehammer to knock out the post.
Step 4: Put one end of the level on the high spot of the floor. Place the other end on a level area of the floor. Use the tape measure to calculate the distance between two spots. Then, measure the length of the old post. The new post should be the equivalent of the length of the old post minus the distance between the two ends of the level.
Step 5: Use the saw to cut the new support post to the correct length. Place the post between the support beam and the pier, where the previous post was located.
Step 6: Lower the jack slowly until the support rests on the support post. Use metal connectors and 8-penny nails to connect the support post to the support beam and the pier. These connectors are made to accommodate particular sizes of framing members.
Step 7: Follow the same post replacement process at each low spot on the floor, with one exception. The support posts should be longer by the measurement reflecting the distance between the two levels in Step 4.
