These jacks provide the extra reinforcement needed to keep beams and joists from shifting or settling unevenly.
I also found that crawl space support jacks help prevent costly repairs down the line. By addressing potential problems early—like sagging floors or uneven foundations—I saved myself from major damage that could have compromised my entire home.

My Buying Guides on Crawl Space Support Jacks
When I first needed to stabilize my crawl space, I quickly realized that choosing the right support jacks was crucial. These jacks help lift and support sagging beams and floors, preventing further structural damage. Here’s what I learned through my search and experience to help you pick the best crawl space support jacks for your project.
Understanding Crawl Space Support Jacks
Crawl space support jacks, sometimes called adjustable steel posts or jack posts, are designed to provide temporary or permanent support to beams and floor joists. They come in various sizes and load capacities, and their main job is to bear weight and prevent sagging.
Types of Support Jacks I Considered
- Steel Telescoping Jacks: These are my go-to for heavy-duty support because they adjust in height and can hold a lot of weight.
- Screw Jack Posts: I liked these for their easy height adjustment via a screw mechanism, giving me fine control over the support level.
- Hydraulic Jacks: While not typically permanent, I used one temporarily when lifting beams before inserting permanent jacks.
Key Factors I Looked at Before Buying
- Load Capacity: It was essential to choose a jack that could handle the weight of my beams and any additional load. I always checked the maximum load rating and chose a higher capacity than what I estimated.
- Adjustability: Since crawl spaces vary in height, I needed jacks with a good range of adjustability to fit snugly between the floor and the beam.
- Material and Durability: I preferred heavy-gauge steel jacks with rust-resistant coatings to ensure long-term durability, especially in damp crawl spaces.
- Ease of Installation: I looked for jacks that were straightforward to install without requiring specialized tools. Some came with easy-to-use screw adjustments or pin locks.
- Base Design: A sturdy base plate helped distribute the load evenly on the ground, preventing sinking into soil or gravel.
Additional Tips From My Experience
- Always measure your crawl space height accurately before buying to avoid ordering jacks that are too short or too tall.
- Consider buying a few extra jacks as spares or for future projects.
- If possible, consult a structural engineer to assess how many jacks you’ll need and where to place them for optimal support.
- Don’t forget safety gear when working in crawl spaces—protective gloves, goggles, and a good flashlight go a long way.
Where I Found the Best Crawl Space Support Jacks
I found reliable jacks at home improvement stores and online marketplaces. Reading customer reviews and product Q&A helped me understand real-world performance before making a purchase. Brands with solid warranties gave me extra confidence.
