Crawl Space Support Jacks in Oklahoma City

Crawl space jacks deliver permanent structural support for sagging, bouncy or unlevel floors in Oklahoma City.

What Are Crawl Space Jacks?

Crawl space jacks are adjustable steel support posts placed beneath beams, girders and floor framing to steady sagging, bouncy or uneven floors. These crawl space jack posts transfer structural loads into stable footings below as part of an engineered crawl space repair system.

Some floors may rely on wood posts, masonry columns or other supports that can deteriorate, settle or shift over time. Adjustable crawl space jacks replace or supplement inadequate supports to restore reliable structural support in the crawl space.

Symptoms

Signs Crawl Space Support Is Needed

Trouble with the beams, floor joists or supports in a crawl space often appears in the floors and finishes above. Signs that the floor system may need additional structural support include:

  • Sagging or pitched floors
  • Bouncy or unlevel floors
  • Gaps between floors and walls
  • Cracks in drywall and interior finishes
  • Doors or windows that bind
  • Deteriorated support posts or framing: Rot, corrosion or other damage can reduce the ability of existing components to support the floor system.
  • Settled or shifting piers and posts: Existing supports may settle or shift, leaving beams and floor joists inadequately supported.
  • Changes to building loads: Remodels, equipment or other added loads may require more support than the existing floor system provides.

These signs don’t necessarily mean more jack posts are needed. A structural evaluation can identify the cause of the movement and show whether crawl space support jacks, framing repairs or another solution is appropriate.

SmartJack® Capacity & Performance

  • Engineered to Support Significant Structural Loads

    Engineered Load Ratings

    The SmartJack® system relies on engineered steel components designed to move loads from the beam or girder above to the supporting soils below. The assembled steel components are rated for an allowable system capacity of 30 kips (30,000 pounds). Actual allowable loads for an installed system depend on the supporting soils, footing design and other site conditions.

    • 30-kip allowable capacity for the assembled steel components
    • Engineered to handle axial compression loads
    • Provides support for beams, girders and floor framing
    • Engineered steel components designated for structural support

  • System Capacity Depends on More Than the Jack Post

    Support from the Framing to the Soil

    A crawl space support system is only as effective as the ground supporting it. While SmartJack steel components are rated to a 30-kip allowable capacity, actual allowable loads can be limited by the bearing capacity of the underlying soil. Proper footing design helps distribute structural loads and reduce the potential for settlement.

    • Carries loads through the post and footing into supporting soils
    • Footing requirements can be engineered for site conditions
    • Factors in soil bearing capacity when determining allowable loads
    • Creates a complete load path rather than relying on the post alone

  • Stabilization with the Ability to Make Controlled Adjustments

    Adjustable Steel Support Posts

    SmartJack support posts have an adjustable connection that allows the system to be tightened during installation. When conditions allow, controlled adjustments may also help improve sagging or uneven floor areas. The system can be adjusted later if additional correction is appropriate.

    • Adjustable at the time of installation
    • Helps stabilize sagging beams and floor joists
    • May allow floors to be raised toward a more level position
    • Can be readjusted if conditions call for it
How it works

How Crawl Space Jack Installation Works

1.

Assess the Floor System

Inspect the beams, floor joists, existing supports and areas of sagging or movement to understand the structural picture.

2.

Map Out Support Locations

Determine where SmartJack® support posts are needed based on the floor framing, existing supports and load requirements.

3.

Build the Base

Excavate each support location and install the specified aggregate base and footing to distribute loads to the supporting soil.

4.

Install the SmartJack® System

Position and secure the adjustable steel support posts beneath the beam or girder to establish a load path from the floor system down to the footing below.

5.

Adjust & Verify Support

Make controlled adjustments to steady the floor system and, when conditions allow, help raise sagging areas toward a more level position.

Why Choose SmartJack® Over Other Crawl Space Support Posts?

Not every post installed beneath a floor system provides the same level of support. Wood posts, masonry piers and temporary jack posts may deteriorate, settle or lack the footing and load capacity required for long-term structural support.

The SmartJack® system combines engineered steel support posts, adjustable connections and properly designed footings to create a complete load path from the floor framing to the supporting soil.

Engineered Steel Construction
SmartJack® is built as a structural support system rather than an improvised or temporary floor support.

Adjustable Support
The system can be adjusted at installation to stabilize the floor framing and, when conditions allow, help lift sagging areas toward a more level position.

Designed for the Load Below
SmartJack® footings distribute structural loads into the supporting soil, which helps address one of the common causes of settled or inadequate crawl space supports.

This is for logan and rolo who showed up at the appointed time and did a great job. they had a breakdown of equipment and had to come back the day after but were prompt to finish the job. During the repair, a car became stuck in a neighbors driveway and they were the first to help the person- to help someone else in need. I was really impressed with that. I give a 5 star review and rating. I plan to do additional work because they would be doing it. I enjoyed their friendliness and workmanship.

Brent M. | Coweta, OK

Everything went as expected, maybe a little better! Very nice crew, enjoyed the installation all around!

Bob H. | Tulsa, OK

Gino H. from Shawnee, OK purchased a charming old home built in 1939 with a full basement. Expanding soils that are so prevalent in many areas of OK exert an enormous pressure on foundations. As a result, most homes with full basements will eventually develop some sort of structural issue over time. When Gino learned about the problems, he decided to call Vesta Foundation Solutions for help. In this video, he speaks about his experience with the company. He is so happy with the service that he is hiring the company again, to repair another one of his properties. “I would absolutely recommend Vesta Foundation Solutions to any friends or family,” says Gino.

Gino H. | Shawnee, OK

“We knew something wasn’t right when the doors stopped closing properly and cracks started showing up. The Vesta team walked us through everything with total transparency. The crew was professional, fast, and left our place cleaner than they found it. Now our home feels solid again, and we finally have peace of mind.”

David R. | Luther, OK

“I’ll give the guys (Cory and Jose) a great 5+ rating. Great, efficient installation. They were very pleasant and professional.”

Nancy S. | Guthrie, OK

“We had no idea how bad things had gotten under our house until the Vesta team showed us the damage. They were honest, thorough, and explained everything clearly. The crew worked efficiently, replaced the damaged wood, and gave our floors the support they needed. It’s such a relief to walk through the house and not feel everything shifting. We’re incredibly thankful for the work they did.”

Sally B. | Nicoma Park, OK

Bryan and Cornileus were amazing. Our project was huge and required a lot of heavy lifting. Every day, they came to work with smiles on their faces and were hardworking the entire time. Bryan was great at communicating the process and what to expect. He would call me every morning to let me know where he was and at what time to expect him. Very reliable. They both are great around kids and were a joy to have in our home! Thanks guys!!

Shelby D. | Crescent, OK

I had a sinking concrete apron around my pool. I was considering replacing the concrete, which is very expensive, or “mudjacking” the concrete back in position. For about the same price as mudjacking, I hired Vesta Foundation Solutions to inject a polymer in the ground and bring the concrete back in position. I was very pleased with the results, and I feel I saved a considerable amount of money from other solutions available to me. William Blake, the hands-on owner, did an excellent presentation of his product. The work was completed in a timely manner by Adam and Daniel, who took extra time to explain the process as they were doing the work. The work site was cleaned up when the fellows were finished, and Mr. Blake reviewed the finished work to ensure I was satisfied. I am very satisfied with this type of concrete lifting process, and I can certainly recommend the workforce at Vesta Foundation Solutions for their professionalism, thoroughness, and friendliness in getting the work done.

David O. | Edmond, OK

Ricardo and his team did an excellent job installing my 10 piers. He was very informative, polite, and took good care of my yard and my house. Definitely would use them again.

Crawl Space Jacks FAQs

How much do crawl space jacks cost?2026-10-06T13:42:28-05:00

Cost depends on the number of SmartJack® supports required, their placement and height, footing requirements, crawl space access and whether beams, joists or other structural components also need repair. Vesta Foundation Solutions can assess the floor-support system and provide pricing based on the recommended repair design. 

Can a building remain occupied during crawl space jack installation?2026-10-06T13:41:43-05:00

Usually, yes. Since SmartJack® installation is typically performed from within the crawl space, major demolition of the occupied space above may not be necessary. Access requirements, structural conditions and the repair scope determine whether any areas of the building need to be temporarily restricted. 

How long does crawl space jack installation take?2026-10-06T13:41:10-05:00

Installation time depends on how many supports are needed, crawl space access, existing framing, footing requirements and whether other structural repairs are needed. Many projects can be completed with relatively limited disruption because the work takes place primarily within the crawl space. 

Can crawl space jacks replace rotted wood posts?2026-10-06T13:40:36-05:00

Yes, crawl space support jacks may be used in place of deteriorated wood posts when they are part of the building’s support system. Any rot or deterioration in the beams or joists being supported should also be evaluated, since setting a new post does not repair damaged framing.

Do crawl space jacks need concrete footings?2026-10-06T13:39:55-05:00

Crawl space jacks need a properly designed base to distribute loads into the soil, but that does not necessarily mean a traditional poured concrete footing. SmartJack® installations can use engineered footing configurations chosen according to the loads and site conditions. 

How many crawl space jacks are needed?2026-10-06T13:39:14-05:00

There’s no fixed number. The quantity and spacing come down to framing, beam spans, loads, existing supports and the capacity of the soil and footings below. An evaluation is needed to determine the right number and placement of support posts for the project. 

Can SmartJack® supports be adjusted later?2026-10-06T13:38:36-05:00

Yes. SmartJack® support posts have an adjustable connection that allows controlled adjustments during installation and, when appropriate, at a later date. This can help when additional correction of the supported floor system is needed. 

Are crawl space jacks permanent?2026-10-06T13:37:57-05:00

Yes. SmartJack® is engineered as a permanent structural support system. Unlike temporary jack posts and improvised supports, it combines engineered steel components with a footing designed to transfer loads from the floor framing to the supporting soil. 

Can crawl space jacks level a sagging floor?2026-10-06T13:37:15-05:00

Yes, in many cases. SmartJack® supports can be adjusted to help lift sagging beams and floor framing toward a more level position while stabilizing the floor system. How much correction makes sense depends on the condition of the framing, the amount of movement and other structural considerations. 

How do crawl space jacks work?2026-10-06T13:36:33-05:00

Crawl space jacks are installed under beams or girders to provide additional support for the floor system above. The post carries structural loads down through a footing and into the supporting soil. SmartJack® posts are adjustable, which allows the system to be tightened and the floor framing stabilized during installation. 

How much weight can a SmartJack® support?2026-10-06T13:35:47-05:00

The assembled steel components of the SmartJack® system have an allowable capacity of up to 30 kips, or 30,000 pounds. That said, the allowable load for an installed system also depends on factors such as soil bearing capacity, footing design, post height and project conditions. Each application should be evaluated based on the structure and loads being supported.
