Is your crawl space encapsulation worth the cost, or will a quick support fix do the job? It depends on what's actually happening underneath the house. American Fork Foundation Pros checks support posts, beam condition, and moisture levels before recommending either one, since older core American Fork homes often have crawl spaces that have taken on decades of seasonal moisture swings.

Sagging floors and a musty smell underneath usually mean the support structure or the moisture barrier, or both, has failed. We fix the support first, then decide if full encapsulation makes sense for the space.

What's included

What's included

Typically included: crawl space inspection, support post evaluation, adjustable jack installation, vapor barrier install. Optional: full encapsulation with sealed seams, dehumidifier unit, insulation panels. Customer prep: clear crawl space access point, remove stored items from the crawl space if present.

How it works

How our Crawl Space Repair process works

  1. Crawl Space Inspection photo
    Step 1

    Crawl Space Inspection

    The area is assessed for moisture, sagging, and structural issues.

  2. Support Evaluation photo
    Step 2

    Support Evaluation

    Existing support posts and beams are checked for damage or deflection.

  3. Moisture Control Planning photo
    Step 3

    Moisture Control Planning

    A plan is created to address humidity and water intrusion sources.

  4. Support Installation photo
    Step 4

    Support Installation

    Adjustable jacks or piers are installed to correct sagging areas.

  5. Encapsulation photo
    Step 5

    Encapsulation

    A vapor barrier is installed to seal the crawl space from moisture.

  6. Ventilation Check photo
    Step 6

    Ventilation Check

    Airflow and humidity levels are verified after completion of work.

Materials

Materials and methods for Crawl Space Repair

Older crawl spaces here see more moisture swing than newer builds, so materials are picked for durability, not just a quick seal.

  • Adjustable Steel Jacks photo

    Adjustable Steel Jacks

    support sagging floor joists and beams from beneath, built to carry load long-term.

  • Vapor Barrier Liner photo

    Vapor Barrier Liner

    blocks ground moisture from rising, sized at 6-20 mil for Utah's humidity swings.

  • Dehumidifier Unit photo

    Dehumidifier Unit

    maintains safe humidity in enclosed crawl spaces where airflow alone isn't enough.

  • Insulation Panels photo

    Insulation Panels

    help regulate temperature swings common in older crawl space construction.

  • Support Beams photo

    Support Beams

    replace or reinforce beams weakened by years of moisture exposure.

  • Sealant Tape photo

    Sealant Tape

    secures vapor barrier seams for a continuous, durable moisture seal.

FAQs

Crawl Space Repair FAQs

Is crawl space encapsulation worth it in Utah?

For older homes with persistent moisture or musty smell, yes. It controls humidity, protects wood framing from rot, and can improve indoor air quality above the crawl space.

How do I know if I need support jacks or just a vapor barrier?

If floors sag or feel bouncy, that's a support issue needing jacks or beam work. If the problem is just moisture smell without structural sagging, a vapor barrier alone may be enough.

How much does crawl space support cost?

Support jack installation typically runs $2,000 to $6,000 depending on the number of points needed. A free estimate narrows that down for your crawl space.

Can I install a vapor barrier myself?

A basic barrier is a possible DIY project, but proper sealing at seams and perimeter is what makes it effective long-term, which is where most DIY attempts fall short.

Do I need a permit for crawl space support work?

Structural beam or jack installation typically needs a Utah County permit. Vapor barrier work alone usually doesn't.
