Support Sagging Floors with House Jacks in Oklahoma City

Sagging, uneven or bouncy floors often signal that the support system beneath your home needs attention. When crawl space support posts settle or floor framing weakens over time, the right solution goes beyond simply lifting the floor; it requires restoring long-term structural support.

House jacks, also called crawl space jacks or floor support jacks, are engineered to strengthen and stabilize your home's floor support system. At Vesta Foundation Solutions, every repair starts with a thorough structural inspection to identify what's causing the problem. From there, we'll recommend a customized floor stabilization solution designed to support weakened floor joists, reinforce your crawl space and help protect your home for years to come.

What Are House Jacks?

House jacks are adjustable steel support posts that stabilize sagging floors by reinforcing weakened floor joists and beams from below your home. Installed in a crawl space or basement, they transfer structural loads down to a stable foundation beneath your home.

Unlike temporary jack posts or wood supports, engineered house jacks are meant to be a long-term structural repair. They help limit floor movement, improve stability and, in many cases, lift sagging floors closer to their original position.

Every home is different, which is why the right repair starts with a thorough inspection. We'll assess your floor framing, crawl space conditions and structural supports to determine whether house jacks are the best solution for your home.

What Causes Crawl Space Structural Damage?

Crawl space structural damage often develops gradually as moisture, shifting soils and aging materials weaken the floor support system beneath your home. High humidity, poor drainage, freeze-thaw cycles and older vented crawl spaces can all contribute to wood deterioration, settling support posts and unstable soil. Eventually, these conditions may cause floor joists and beams to lose support, leading to sagging, uneven or bouncy floors.

Our Crawl Space Support Solution

There’s always an underlying cause behind a sagging floor, which is why every repair begins with a thorough structural inspection. If weakened floor supports are behind the problem, we’ll recommend a permanent solution designed to stabilize your home’s floor system for the long term.

How It Works

Our SmartJack® Installation Process

Here’s how we inspect, design and install a customized SmartJack® support system to stabilize sagging floors and strengthen your home’s crawl space.

Step 1

Inspect Your Crawl Space & Floor System

Every project opens with a comprehensive structural inspection. We’ll inspect your crawl space, floor framing, support beams and soil conditions to pinpoint what’s causing your floors to sag and determine whether SmartJack® is the right solution.

Step 2

Prepare a Stable Foundation

Our team prepares a solid, engineered base at each support location to provide long-term stability. This base is designed to help distribute the weight of your home and support the SmartJack® system for lasting performance.

Step 3

Set & Adjust the SmartJack® System

Each galvanized steel support post is sized to your crawl space and securely installed beneath weakened floor joists or beams. The system is then carefully adjusted to reinforce the floor structure and, in many cases, improve how level your floors sit.

Step 4

Enjoy Long-Term Floor Support

After installation is complete, your home benefits from a stronger, more stable floor system built to reduce movement and provide lasting structural support. SmartJack® is adjustable, so it can also be fine-tuned if needed in the future.

Symptoms

Warning Signs Your Home May Need a SmartJack® System

Sagging floors rarely get better on their own. If you’re noticing changes in how your floors feel or other signs of structural movement, your crawl space support system may need attention. A professional inspection identifies the underlying cause and determines whether SmartJack® is the right solution. Common Signs Include:

  • Floors that sag or slope
  • Bouncy or springy floors
  • Soft or unstable-feeling floors
  • Squeaky floors that are getting worse
  • Gaps between floors and baseboards
  • Crawl space support posts that are leaning, rotting or failing

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.

Frequently Asked Questions

How much do house jacks cost? 2026-10-02T09:45:48-05:00

The cost of installing house jacks varies based on your home’s size, the number of supports needed, crawl space accessibility and existing structural conditions. Because every repair is customized, there’s no one-size-fits-all price. A free professional inspection is how we provide an accurate recommendation and estimate for your home. 

How do I know if my home needs house jacks or another repair solution? 2026-10-02T09:45:21-05:00

The only way to know for sure is through a professional structural inspection. Sagging or uneven floors can stem from several issues, including weakened floor framing, failing support posts, foundation settlement or moisture damage. We’ll pinpoint the root cause and recommend the repair that’s best suited for your home, not simply install a product. 

Will house jacks continue to be adjusted over time? 2026-10-02T09:44:55-05:00

SmartJack® support posts are adjustable, allowing for precise installation and minor future adjustments if needed. Depending on your home’s condition and repair plan, we may recommend additional adjustments as the structure settles and responds to the new support system. 

How long does house jack installation take? 2026-10-02T09:44:27-05:00

Most house jack installations are completed in one to two days, though larger or more complex projects may take longer. The schedule depends on the size of the crawl space, accessibility, the number of supports required and whether additional structural repairs are needed. Your inspector will go over what to expect before work begins. 

Can house jacks level uneven floors? 2026-10-02T09:43:59-05:00

In many cases, yes. House jacks help lift and stabilize sagging floors, improving floor levelness and reducing bounce. Every home is different, though, and the amount of correction depends on the condition of the framing, how long the floors have been sagging and the home’s overall structural condition. 

Are house jacks a permanent solution? 2026-10-02T09:43:26-05:00

Yes, when installed correctly. Professionally installed house jacks are meant to be a long-term structural repair, not a temporary fix. Installed on a properly prepared base and paired with the appropriate repair plan, they provide lasting support for weakened floor systems while addressing the underlying cause of the problem. 

How do house jacks fix sagging floors? 2026-10-02T09:42:40-05:00

House jacks stabilize sagging floors by carrying the weight of your home’s floor system down to a stable, engineered base beneath the crawl space. This added support reinforces weakened joists and beams, helping cut down on floor movement and, in many cases, improving floor levelness. The system is tailored to your home’s specific structural needs. 

What are house jacks? 2026-10-02T09:41:53-05:00

House jacks are adjustable steel support posts designed to strengthen weakened floor joists and beams from beneath your home. Installed in a crawl space or basement, they provide permanent structural support where existing supports have settled or deteriorated. Professionally engineered house jacks help stabilize sagging floors and strengthen your home’s floor system for long-term performance.
