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 our Crawl Space Repair process works
Step 1Crawl Space Inspection
The area is assessed for moisture, sagging, and structural issues.
Step 2Support Evaluation
Existing support posts and beams are checked for damage or deflection.
Step 3Moisture Control Planning
A plan is created to address humidity and water intrusion sources.
Step 4Support Installation
Adjustable jacks or piers are installed to correct sagging areas.
Step 5Encapsulation
A vapor barrier is installed to seal the crawl space from moisture.
Step 6Ventilation 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
Support sagging floor joists and beams from beneath with engineered, load-rated capacity.

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

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

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

Support Beams
Replace or reinforce weakened structural beams found in older subdivisions.

Sealant Tape
Secures vapor barrier seams for a continuous moisture seal.

DIY vs hiring a pro for Crawl Space Repair
| DIY | Hire a pro |
|---|---|
| A homeowner can lay a basic plastic sheet for minor moisture reduction | Store-bought jack posts aren't load-rated for structural support the way engineered steel jacks are |
| Spot-checking for visible sagging or moisture is reasonable before calling anyone | Sizing a jack to the actual load above it requires measurement a DIY post doesn't account for |
| — | Vapor barrier installed without sealed seams often fails within a season |

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.
