Crawl Space Structural Repair
Fix sagging floors, damaged joists, and structural issues before they compromise your home's integrity.
What is Crawl Space Structural Repair?
Crawl space structural problems — sagging floors, damaged floor joists, deteriorating beams, and compromised support columns — are often the result of long-term moisture exposure. Moisture weakens wood framing through rot, fungal decay, and insect damage, eventually causing visible symptoms like uneven floors, bouncy spots, and cracking above doorways. Professional structural repair addresses both the damage and its cause, restoring your home's stability.

Our Process
Structural Assessment
A certified professional evaluates floor joists, beams, columns, and subfloor for damage, measuring deflection and identifying compromised members.
Support Installation
Adjustable steel crawl space jacks or supplemental columns are installed to support sagging areas and level floors.
Joist Repair
Damaged joists are repaired through sistering (attaching new lumber alongside damaged joists) or full replacement.
Beam Replacement
Deteriorated main beams or girders are replaced or reinforced with steel or engineered lumber.
Moisture Prevention
The moisture source that caused the structural damage is addressed to prevent recurrence — typically through encapsulation and/or waterproofing.
Typical Cost
$2,000–$10,000+

Crawl Space Structural Repair FAQ
The most common cause is moisture damage to floor joists and beams. Over time, moisture causes wood rot, fungal decay, and attracts wood-destroying insects. Joists lose structural capacity and begin to deflect under the weight of your home. Inadequate original support (too few columns, undersized beams) can also contribute.
