Common Crawlspace Problems

An unhealthy crawlspace affects your entire home. Up to 50% of the air you breathe on the first floor comes directly from your crawlspace. If it is damp, rotting, or settling, your home's structural integrity is at risk.

Moisture & Rot

Open vents and exposed dirt floors allow humidity to rot wooden floor joists and subflooring.

Sagging Floors

As support columns settle into soft soil or joists weaken from moisture, floors above become uneven and bouncy.

Pest Infestations

Damp, dark crawlspaces are the perfect breeding ground for termites, rodents, and other destructive pests.

Our Proven Solutions

Structural Stabilization

We install heavy-duty steel support jacks that rest on solid bases, lifting and stabilizing sagging floor joists permanently.

Crawlspace Encapsulation

We seal off the crawlspace from the earth and outside air using a thick, durable vapor barrier, dramatically reducing moisture.

The Myth of Crawlspace Vents

For decades, building codes required crawlspaces to be vented to the outside, believing it would let the space "breathe." In reality, letting hot, humid summer air into a cool crawlspace causes massive condensation. The modern, scientifically proven solution is complete encapsulation to seal the moisture out.
