Crawl Space Mold Treatment & Wood Sealing in the Texas Panhandle and Northwest Texas

Treat existing mold while helping protect crawl space wood from future growth with MoldEx and LumberKote from Legacy Supportworks.

Why Mold Gets Started in the Texas Panhandle and Northwest Texas Crawl Spaces

Crawl space mold takes hold when moisture lingers around wood framing. Humid air, damp soil, leaks or water intrusion can drive up moisture levels, creating conditions where mold can develop on joists and subfloors. You might see white or gray growth, musty odors or changes in the floors above.

Left alone, ongoing moisture can contribute to dry rot damage, weakened framing and sagging floors.

Symptoms

Signs You May Need Crawl Space Mold Treatment

Mold in a crawl space isn’t always obvious from inside your home. Some signs appear on the wood below, while others surface as odors or changes to the floors above. It’s worth scheduling a professional inspection if you notice:

  • White, gray or dark growth on the floor joists or subflooring
  • Lingering musty odors in the crawl space or living areas
  • Damp, stained or discolored wood
  • Condensation or high humidity beneath your home
  • Cupping or other shifts in the floors above
  • Mold that reappears after cleaning

Our MoldEx & LumberKote Crawl Space Treatments

  • Treats Existing Mold on Crawl Space Wood

    MoldEx Mold Treatment

    MoldEx is applied directly to the affected floor joists, subflooring and other wood surfaces to treat existing mold growth and staining. The treatment gets into areas where growth is present, helping clean and restore the appearance of the wood. Once treated, the crawl space framing looks cleaner and is ready for whatever additional moisture-control or protective measures the home may need.

    • Treats the existing mold growth on crawl space wood
    • Goes directly on affected joists, beams and subflooring
    • Addresses mold before protective sealing or other crawl space improvements
    • Reaches difficult-to-access wood surfaces throughout the crawl space
    • Helps eliminate visible mold as part of a broader moisture-control strategy

  • Protects Crawl Space Wood Once Treatment Is Done

    LumberKote Framing & Subfloor Sealer

    LumberKote is a protective coating for crawl space floor joists, beams and subflooring. It puts a durable barrier over the wood to help protect treated or vulnerable surfaces from future moisture-related damage and mold growth. Once applied, the framing takes on a clean, uniform finish that adds a visible layer of protection throughout the treated area.

    • Helps protect wood from moisture, moisture-related damage and wood-destroying mold
    • Built on advanced polymer technology
    • Certified FEMA Flood Grade rated
    • Helps dry out and stabilize the lumber’s moisture content, even when moisture-related damage has already begun
    • Comes with a transferable, 30-year warranty
How It Works

What Treatment Day Looks Like

1

Treating the Wood and Protecting It

Before the treatment begins, your crew prepares the crawl space based on what was identified during your inspection and moisture readings. MoldEx is applied to the affected wood surfaces and given time to work. When LumberKote is part of the recommended system, it’s then applied to the appropriate framing and subfloor surfaces to create a protective coating over the wood.

2

What Treatment Day Is Like for You

Nearly all of the work happens below your home through the crawl space access, so disruption to your daily routine is usually minimal. Many treatments can be completed in about a day, although larger crawl spaces, heavier mold growth or additional repairs may require more time. In most cases, homeowners can remain in the home while the work is completed.

How to Help Keep Crawl Space Mold from Returning

Treating existing mold is just part of the solution. If excess moisture remains in the crawl space, the conditions can again become favorable for new growth. That’s why Legacy Supportworks also looks for the source of the moisture instead of focusing only on what’s visible on the wood.

Depending on your crawl space, the solution may include controlling humidity, addressing water intrusion or sealing the space from outside air and ground moisture. Encapsulation and other crawl space repair solutions can help produce a drier environment and limit the conditions mold needs to grow.

Benefits

Crawl Space Mold Treatment You Can Count On in the Texas Panhandle and Northwest Texas

Mold in your crawl space can have more than one cause, so treatment can't be one-size-fits-all. Legacy Supportworks inspects your crawl space for mold growth, wood condition, humidity, water intrusion and other conditions that could be contributing to the problem.

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. from Amarillo, TX hired Legacy Supportworks to help lift and level a sinking kitchen floor with PolyLevel™.In this video he talks about the experience with the company. “We were really impressed that he (the owner) was willing to get in there and work just like a laborer!”

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.

Karen H. | Lubbock, TX

Before & after photos

  • 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

Can I just spray the mold on my floor joists myself? 2026-10-05T11:29:52-05:00

Spraying visible mold may clean the surface, but it may not address growth elsewhere or the moisture problem causing it. Some household cleaners can also discolor or damage wood without offering lasting protection. A crawl space professional can gauge how widespread the problem is, treat affected surfaces and pinpoint what needs to change to help keep the mold from coming back. 

How much does crawl space mold treatment cost in the Texas Panhandle and Northwest Texas?2026-10-05T11:29:06-05:00

Crawl space mold treatment costs vary depending on the size of the crawl space, how much wood is affected, the treatment required and whether moisture or structural problems must be addressed, too. Because no two crawl spaces are alike, an inspection is the best way to determine the scope of work. Legacy Supportworks provides free inspections and estimates for homeowners in the Texas Panhandle and Northwest Texas.

Does LumberKote prevent mold from coming back?2026-10-05T11:28:18-05:00

LumberKote helps shield crawl space wood, but lasting protection also depends on controlling the moisture that contributed to mold or wood damage in the first place. If the crawl space has high humidity, water intrusion or other moisture problems, Legacy Supportworks might recommend additional solutions to keep the space drier and help protect the framing long term. 

How long does MoldEx and LumberKote treatment take?2026-10-05T11:27:34-05:00

Treatment time depends on the size of the crawl space, the amount of affected wood and whether other repairs or moisture-control work is needed. MoldEx and LumberKote are often part of a larger crawl space repair project, so the total timeline varies by home. Legacy Supportworks will explain the recommended treatment and expected installation timeline after inspecting your crawl space. 

Do I need mold treatment before crawl space encapsulation?2026-10-05T11:26:40-05:00

If active mold is present, it should typically be addressed before the crawl space is encapsulated. Encapsulation helps control the moisture conditions mold needs to grow, but it doesn’t clear existing growth from joists or subflooring. Legacy Supportworks can evaluate both the mold and its moisture source to determine whether treatment, encapsulation or a combination of solutions is appropriate.

Is mold in a crawl space dangerous to my family?2026-10-05T11:25:38-05:00

Mold in a crawl space shouldn’t be ignored. Mold spores and musty odors can move with air from the crawl space into the living areas above, potentially impacting indoor air quality. The level of concern depends on the type and extent of the growth and individual sensitivities. A professional inspection can assess the extent of visible growth and, just as importantly, the moisture conditions allowing it to develop.
