Serving Sandy and nearby communities.

Older subdivisions across Sandy and White City, many built in the 1970s and 80s, commonly sit on crawl space foundations rather than full basements. Those crawl spaces are reaching the age where support jacks sag and moisture barriers wear thin.

A bouncy floor or a musty smell under the house usually traces back to one of two things: joists losing support, or ground moisture with nowhere to go. Sandy Foundation Pros checks both before recommending a fix, since replacing a jack post won't help if the real issue is standing moisture underneath.

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 Sandy-area crawl spaces often have original support posts that were never load-rated for today's structure weight or decades of soil movement.

  • Adjustable Steel Jacks photo

    Adjustable Steel Jacks

    Support sagging floor joists and beams from beneath with engineered, load-rated capacity.

  • Vapor Barrier Liner photo

    Vapor Barrier Liner

    Covers the ground to block moisture from rising into the crawl space, a common issue in older builds.

  • Dehumidifier Unit photo

    Dehumidifier Unit

    Maintains safe humidity levels within the crawl space year-round.

  • Insulation Panels photo

    Insulation Panels

    Help regulate temperature and reduce energy loss through the crawl space floor.

  • Support Beams photo

    Support Beams

    Replace or reinforce weakened structural beams found in older subdivisions.

  • Sealant Tape photo

FAQs

Crawl Space Repair FAQs

Do sticking doors and sloped floors always mean foundation settlement?

Not always. In homes with crawl space foundations, a bouncy or sloped floor is often a joist support issue rather than foundation settlement. An inspection tells you which one you're dealing with.

How much does crawl space repair cost?

Vapor barrier alone runs a few thousand dollars. A full package with support jacks and encapsulation costs more, scaled to square footage and the number of support points needed.

How long does crawl space repair take?

Most jobs finish in one to two days depending on crawl space size and how many support points need correction.

Is DIY crawl space repair a good idea?

A basic moisture sheet is fine as a stopgap. Structural support work isn't a DIY project since store-bought jack posts aren't engineered for the load.

What causes a musty smell in older crawl spaces?

Ground moisture with no vapor barrier is the usual cause, especially in homes built before encapsulation was standard practice.
