Crawl Space Support Posts

Sagging floors, weakened beams, and unstable support systems can be signs of structural issues beneath your home. DBS Repair provides professional Crawl Space Support Posts using the SmartJack® system to permanently stabilize and lift sagging crawl space beams and girders. Installed on a foundation-grade steel base and adjustable for future leveling, these support posts help restore structural integrity and improve the long-term stability of your home.

SmartJack® Crawl Space Support Posts:

Permanent, Adjustable Floor Support

The SmartJack® system is a patented adjustable steel support post engineered specifically for crawl space floor beam support. It replaces failing wood posts, deteriorating block stacks, and inadequate shimmed supports with a permanent, galvanized steel solution that will not rot, rust, or shift.

Each SmartJack® post is installed on a steel base plate that is set in poured concrete, creating a stable, engineered footing directly under the sagging beam. The post is then adjusted to lift the beam back toward its original position.

Because SmartJack® posts are adjustable, our crews can return in the future to make additional incremental lifts if needed without reinstalling or replacing the system.

Manufactured from high-strength galvanized steel
Corrosion-resistant coating for long-term performance
Compatible with poured concrete, block, and brick walls
Wall plate installed inside; earth anchor installed in yard
Connected by a steel rod tensioned for immediate stability
Can be retightened over time to straighten walls gradually

What to Expect

1.

Free on-site inspection and estimate

A DBS foundation specialist visits your home to assess wall movement, measure deflection, and determine the correct anchor type and placement.

2.

Base plate footing preparation

At each post location, a hole is excavated and a concrete footing is poured to engineered specifications to serve as the base of the SmartJack® post.

3.

Post installation and beam engagement

The galvanized steel post is set on the base plate and the top bracket is positioned under the sagging beam or girder.

4.

Incremental lift

The post is adjusted to begin lifting the beam. Lift is applied incrementally to avoid cracking drywall or finishes above.

5.

Cleanup and documentation

Crawl space is cleaned, warranty documentation is issued, and adjustment instructions are provided for future maintenance lifts.

Why SmartJack® Outperforms Traditional Crawl Space Posts

Will Not Rot or Corrode

Will Not Rot or Corrode

Unlike wood posts that are prone to moisture damage, mold, and rot in crawl space environments, SmartJack® galvanized steel holds up indefinitely in crawl space conditions.

Adjustable for Future Leveling

Total Foundation Replacement

The adjustable top plate allows DBS crews to return and apply additional lift over time without removing or replacing any part of the installed system.

Engineered Concrete Footing

Total Foundation Replacement

Each post sits on a poured concrete footing designed to the load requirements of that post location, not a simple pad or block.

One-Day Installation

Total Foundation Replacement

Most SmartJack® installations are completed in a single day with no major disruption to the home above the crawl space.

25-Year Warranty

Total Foundation Replacement

Backed by a 25-year manufacturer’s warranty plus DBS’s own in-house performance warranty on all labor and installation.

Everyone was great! We got exactly what we needed with no guesswork. The crew communicated often and well and were all very friendly. We came across some pretty bad foundation issues which the crew was able to immediately address at a reasonable cost. And they were happy to come back for a couple of touch-ups the next week. Overall, we’re very happy with the whole process and result.

We were stumped about how to address our aging cabin's foundation issues. DBS clearly understood what was causing the problem and how to fix it. At a follow up visit one year later, the foundation is right where they moved it.

Trevor and Corbin worked non stop on both sides of our duplex. Eventho mold removal was not on my original work order, they got that taken cars of too. Kept me up to date on everything. And then the final walk through was so educational. I didn’t know how much DBS can do with a basement to make the foundation so much more stable. I am so satisfied with their work, and I’m a nick picker. Thank you guys for all your hard work and making our place a safer place to live.

June 24, 2026 Trevor, with DBS foundation, base and insulation, just completed work on my Madeline Island Cottage on Lake Superior. The work, included Excavation, shoring and replacement supports in the Crawl Space of this 1940 Lake home. I was pleased with the technology at DBS uses, and the knowledge and technical proficiency that Trevor had in doing the work. He was thorough, and listen ed carefully to my concerns. I was absolutely 100% satisfied with his work and that of his assistant Corbin. If you are in need of foundation repair in Minnesota and Wisconsin, I highly recommend DBS. Donald W Laukka, architect.

I recently had DBS perform warranty work on foundation piers for a cabin boathouse. The crew was incredible. Their work was top notch. The foreman, Trevor, was particularly impressive. Highly skilled, outstanding attention to detail, and very customer focused. He also took the time to communicate and teach his younger crew. A true leader in every sense. DBS... be sure to reward employees like Trevor; people like him are difficult to find!

We can NOT thank DBS enough for all their hard work. Lawson and Bryce started our home foundation project. Both were kind, courteous, and professional. The next part of the job was lead by Trevor and Wayne. Both of these guys were excellent too. My husband and I are amazed at how much work they got done in the time they were under my home.Trevor was great at letting us know where they were at and what they were doing just to keep us updated. We are so thankful for their hard work and now feel more secure in our home. Our entire process with DBS from start to finish was excellent and we are so glad we chose them to help fix our home. Shoutout Beverly for aslo assiting me during this process. THANK YOU DBS.

DBS did a great job. James was great figuring out my problem, dip in the floor. I have an old house and the beam had begun to rot. Trevor and a couple other gentlemen were out to do the work. They were all real polite and explained the process. Trevor also pointed out some fun facts about my house. If I need anything else done I would for sure trust them to do the work. Didn't leave a mess which was also appreciated.

Myke Connelly was great to work with and I truly know that we will be in great hands with DBS moving forward. He was thorough and patient with the many questions we had about what was happening with our foundation project and would certainly suggest everyone in need of reinforcement solutions for your foundation meet with and work with their company. Thank you Myke and thank you DBS!
