Crawl Space Support Jacks in the Texas Panhandle and Northwest Texas

Permanently stabilize sagging, bouncy floors with engineered steel support jacks that shore up weakened beams and floor joists.

What Are Structural Support Jacks?

Crawl space support jacks are engineered, adjustable steel posts set beneath a home to stabilize weakened beams and floor joists. They carry loads down to stable footings below, creating a reliable support system for sagging or bouncy floors.

Unlike the hardware-store jack posts intended for temporary or limited applications, Legacy Supportworks installs structural support jacks designed for permanent crawl space repair.

Symptoms

Warning Signs Your Home Needs Crawl Space Support Jacks

Problems with the beams, joists or columns in your crawl space often show up throughout the rooms above. You may first notice changes in how your floors feel or how your doors and windows operate.

Signs that your home may need additional crawl space support include:

These symptoms don’t always mean support jacks are the correct repair. An inspection can determine what’s behind the movement and whether the existing support system needs to be reinforced.

Crawl Space Support Solutions We Offer in the Texas Panhandle and Northwest Texas

  • Adjustable steel support jacks for sagging, sloping or bouncy floors

    SmartJack® Crawl Space Support Jacks

    The SmartJack® system offers permanent support for under-supported or weakened crawl space beams and floor joists. Each adjustable steel post is installed on a footing built to provide a stable base and properly transfer load.

    After installation, SmartJack posts stabilize the floor system and, when conditions allow, can help raise sagging areas toward a more level position.

    • Permanent support beneath weakened beams and floor joists
    • Adjustable to keep up with changing conditions
    • Can help lift floors toward a more level position
    • Zinc-plated, galvanized steel components resist rust
    • Engineered to carry substantial residential loads
    • Fast, year-round installation with minimal disruption
    • Backed by a written warranty from Legacy Supportworks

  • Repairs Weakened or Damaged Beams and Joists

    Wood Repair and Replacement

    When rot, mold or other deterioration has damaged crawl space beams or floor joists, adding support alone may not solve the problem. Damaged structural wood may need to be reinforced or replaced to restore its strength.

    Wood repair can work alongside SmartJack® support and moisture-control solutions when multiple issues are affecting the floor system.

    • Strengthens or replaces damaged beams and floor joists
    • Restores strength to weakened structural wood
    • Can include sistering new wood alongside existing framing
    • Works with SmartJack support when additional stabilization is needed
    • Pairs with encapsulation when moisture plays a role in the damage
How It Works

How Legacy Supportworks Handles Structural Support Jack Installation

Step 1

Assess the Floor System

We start with a free home inspection, evaluating the beams, joists and existing supports to determine where additional support is needed.

Step 2

Prepare the Footing

At each support location, we excavate the crawl space floor and install an engineered footing to provide a stable base for the system.

Step 3

Install the Steel Support

The steel base, adjustable column and top assembly are positioned under the beam to deliver support where it’s needed. 

Step 4

Stabilize the Floor

Every jack is carefully adjusted to stabilize the floor system and, when conditions allow, help lift sagging areas toward a more level position.

Step 5

Confirm the Repair

The completed system is reviewed to confirm every support is properly positioned and adjusted. 

Consider Supplemental Solutions

When moisture is contributing to structural damage, Legacy Supportworks may also recommend crawl space encapsulation or other moisture-control solutions to help protect the repaired area.

How Much Does Crawl Space Support Jack Installation Cost?

The cost of crawl space support jacks depends on your home and how extensive the structural problem is. Factors include the number of jacks needed, crawl space access, the condition of the floor system and whether additional repairs are required.

A professional inspection is the best way to pin down the right repair and get an accurate estimate. Legacy Supportworks offers financing options and a written warranty for extra peace of mind.

Customer Information

Don't just take our word for it

See what our customers have to say about our work.

Legacy SupportWorks was referred to me by Bernie Sanders with Sir Speedy. When doors began to not close properly and there were noticeable gaps between the floor and molding, we knew it was time to get some foundation work done on our home. We shopped around and were pleased with the value and responsiveness of Legacy Support Works. I felt comfortable with them in my home, they delivered what they promised when they promised and left my home clean. From Tessa who made the initial contact, to the gentleman putting my carpet back in place, customer service was outstanding.

Mike P. | Amarillo, TX

When Karen H. saw some cracks on her wall, she knew something was wrong. She first called a local contractor and they told her that the cracks were being caused by the trees in her backyard. Karen wasn’t convinced by their explanation so she decided to get a second opinion and called Legacy Supportworks. In this video she talks about the experience she had with the company and why she was confident to hire them as the right company for the job. “What we got from Legacy Supportworks was not just a company that will be there for us through the whole process, but be there for us through any other problems that we have in the future”, says Karen.

Before & after photos

Check out before and after photos from some of our completed projects.

  • Stabilizing a Crawlspace in Pampa, TX

    This home had crawlspace beams that were cracking and lacked stabilization. 

    Years of shimming had only been a “band-aid” fix and this customer was looking for a permanent solution.

    Our crew installed steel beams and steel smartjacks on engineered fill.

    The result was a permanently stabilized floor!

  • Concrete Repair in Spearman, TX

    A customer reached out after seeing a video of concrete lifting using injection methods and wondered if it could work for their front porch. Their home, built in 1968, features a large concrete porch with a section that originally had a planter between it and the house. At some point, the planter was covered with concrete, which has since sunk about 4 inches. Both sections measure approximately 8×12. While the porch itself was fine, they wanted a solution to lift the concrete over the old planter rather than starting from scratch. Legacy inspected the situation and provided a tailored solution to restore their home.

  • Foundation Repair in Guymon, Oklahoma

    Just four years after adding a first porch for relaxation, a homeowner in Guymon, OK found himself facing a disheartening problem – his beloved porch had settled a shocking 2 feet into the ground, taking his dreams of peaceful rocking chair afternoons with it. As depicted in our before photo, this alarming sinkage rendered the space unusable. To lift and stabilize the sinking structure, we deployed our trusted Push Pier system, meticulously engineered to provide strength and elevation from deep below the surface. The transformation is apparent in the after photo, where the porch now stands level and secure, promising many future years of comfort and stability. At Legacy Supportworks, reviving your home’s foundation to ensure lifelong enjoyment and safety is not just our mission—it’s our commitment to you.

Frequently Asked Questions

Are hardware-store jack posts the same as professionally installed support jacks?2026-10-02T15:22:56-05:00

No. Hardware-store jack posts aren’t necessarily built or rated as permanent structural repairs. Professional crawl space support systems use engineered components, appropriate footings and planned placement to support the loads above. A structural repair should be selected and installed around the home’s floor system rather than simply placing adjustable posts beneath areas that appear to sag.

How long do structural support jacks last?2026-10-02T15:22:09-05:00

Professionally installed structural support jacks are built as a long-term solution. How long they last depends on the system, materials, installation and crawl space conditions. Systems built with corrosion-resistant steel are specifically designed for the below-home environment. Ask Legacy Supportworks about the warranty provided with your support system and any recommended inspections or adjustments over time.

Do crawl space support jacks need a concrete footing?2026-10-02T15:21:08-05:00

Support jacks need a stable base that can transfer the load from the floor system to the ground below. Depending on the system and site conditions, that may involve concrete or another approved footing. Proper footing design and installation are important, since placing a support post directly on inadequate soil or an unsuitable surface may not provide reliable long-term support.

How much do crawl space support jacks cost in the Texas Panhandle and Northwest Texas?2026-10-02T15:19:44-05:00

Crawl space support jack costs vary with the number of jacks needed, crawl space access, installation requirements and the condition of the existing beams and floor joists. Additional wood repair or moisture-control work can also affect the total. Legacy Supportworks provides free inspections and written estimates, so you know the recommended repair and its cost before work begins. 

How many support jacks does my crawl space need?2026-10-02T15:17:30-05:00

There isn’t a standard number of support jacks for every crawl space. The number and placement come down to the size and layout of the floor system, beam spans, loads, existing supports and areas that need stabilization. A professional inspection can identify where additional support is required and how many jacks are appropriate for your home. 

Can support jacks lift a sagging floor back to level?2026-10-02T15:16:24-05:00

Yes. Adjustable support jacks help lift sagging floors toward a more level position while stabilizing the floor system. How much lift is possible depends on the condition of the framing, how long the floor has been sagging and other factors specific to the home. 

How do you support a floor joist in a crawl space? 2026-10-02T15:15:13-05:00

The right repair depends on why the floor joist is sagging or under-supported. A professional might reinforce damaged joists, add support beneath a beam or install adjustable steel support jacks to transfer loads to stable footings below. The floor system should be assessed first to determine whether the joists, beams, existing columns or a combination of components need repair.
