Jan 14, 2014 · Lifting Up a Sagging Floor – DIY. This job took two people one afternoon. We got muddy because we were in a dirt crawlspace doing just that, crawling. We used 18,000-pound screw jacks, 4×4 lumber, a circular saw, power drill/driver, and cement blocks. Total cost was less than $200, while a pro would charge $500-$1000.
Common materials for replacing a load-bearing wall with a beam & column system are joist hangers, joist hanger nails, LVL’s (engineered beams), 8d framing nails, header material (2×4’s), 16d framing nails, and construction adhesive.

When the beam is in place, the crew sets up shoring posts to hold it in place during the repair. (Hydraulic jacks lift the beam the last few inches and hold it until the posts are in.) Secure the bases. Double-headed nails secure the post bases to the timbers that distribute the loads. Shoring becomes scaffolding.
- Remove the Drywall. Shut off the circuit at the main panel. Remove the baseboards on both sides of the wall and any electrical cover plates. Slice through the tape at inside corners at the ceiling, and at any adjoining walls.
- Cut a Slot in the Ceiling. Snap a chalk line about 12 inches out from the wall and cut a slot. Strip 1 foot of ceiling drywall from one side of the wall.
- Remove Cables from the Stud Wall. Examine the ceiling framing to determine the beam design. Turn off the electrical power and remove electrical cables, outlets and switches and pull the cable free of the studs.
- Build a Temporary Wall. Tack a single top 2×4 plate under the floor joists and another directly below it to the floor. Add a second top plate. Tap in and toenail temporary studs every 2 feet.
A single top plate can be used in load-bearing walls, provided roof rafters or trusses and floor joists stack directly over the studs in the wall. Bottom plates are almost exclusively single. Each wall stud is fastened in place between the plates with two or three nails driven through the plates and 1-1/2 in. or deeper into the ends of the stud.

Typically, the beam will be manufactured 150mm (6″) longer than the span to allow for a minimum bearing surface of 75mm on each end. The beams are made (and priced) on 600mm (2 ...
