From video: How to Straighten Sagging Ceiling Joists with a "STRONGBACK"
Published: March 6, 2026

Video Description

If you’ve got sagging or uneven ceiling joists, installing a strongback is one of the most effective ways to straighten and stiffen them. In this video, I’ll show you how to straighten ceiling joists using a strongback to create a flatter, stronger ceiling frame. I'll cover: • What a strongback is and how it works • How to identify sagging or crowned joists • The tools and materials you’ll need • How to properly position and install the strongback • Tips for jacking joists safely and evenly • Common mistakes to avoid A strongback (typically a straight 2x6 or 2x8 installed perpendicular to the joists) helps distribute loads across multiple joists, reducing bounce and helping correct sag over time. Whether you’re finishing a basement, fixing a wavy ceiling, or reinforcing older framing, this method can make a big difference. 🛠 Tools & Materials Needed: Circular saw- https://amzn.to/4lzcAVv Hammer drill- https://amzn.to/4lDN9SA Construction screws- https://amzn.to/4cQ4Egb Ladder- https://amzn.to/3NdINF8 Level- https://amzn.to/4sYluOR Lumber Check out the other tools used on this and other projects here- http://bit.ly/FixerStore (Affiliate links) Check out my other ceiling joist video- https://youtu.be/iZI5YCVZGtc https://youtu.be/vPtG1weUwPI FULL OFFICE BUILD PLAYLIST https://www.youtube.com/playlist?list=PLKeoAfcTZa1GTcgHpXpda8qUbfXU-avZ6 ⚠️ Always follow local building codes and use proper safety precautions when working overhead.
