Stop Crawlspace Moisture Before It Becomes Damage.
A wet or humid crawlspace doesn’t just create unpleasant odors — it can damage your home’s foundation, worsen air quality, attract pests, and lead to costly repairs. Our complete crawlspace moisture control system is designed to eliminate moisture at the source, protect your home long-term, and keep your indoor environment healthy and dry.
Why Crawlspace Moisture Happens.
Moisture in a crawlspace can come from multiple sources — and if it sits longer than 24–48 hours, the moisture slowly evaporates into the wood, promoting wood destroying fungi and damaging the insulation in the crawlspace. Prolonged standing water or wet soil causes damage to joists, sills and subfloor and makes your crawlspace more attractive to termites and powderpost beetles. Common causes include:
- A damaged or missing vapor barrier
- Standing water that isn’t draining properly
- Groundwater or surface water penetrating from outside
- High humidity in the air
- Poor ventilation or dead air pockets
Many companies only cover the floor with plastic, and in some cases crawlspace encapulation and call it done. We address the actual water problem first.
Our Complete Crawlspace Moisture Control System.
Every home is different, which is why our approach combines multiple proven systems to eliminate moisture at its source—not just mask the symptoms. We tailor each solution to your property’s unique conditions, ensuring long-term protection you can count on.
1. Vapor Barrier Installation
A high-grade vapor barrier seals the crawlspace floor and walls to prevent moisture from entering from the ground. If your current barrier is torn, displaced, or incomplete, we replace it with a durable, long-lasting solution that meets industry standards.
2. Interior French Drain System
If water is entering the crawlspace, the first priority is to move it out.
We install an interior French drain that collects water and directs it outside your home — exactly where it belongs. This prevents standing water from accumulating and soaking into the soil.
3. Crawlspace Dehumidifier
Once moisture intrusion is controlled, we stabilize the environment with a high-efficiency dehumidifier designed for crawlspaces. This keeps humidity levels low, prevents mold growth, and helps your home breathe easier.
4. ATMOX Intelligent Moisture Management
For homeowners wanting the most advanced system available, we offer ATMOX, a smart alternative to traditional encapsulation alone.
ATMOX features include:
- Interior & exterior humidity sensors
- Automated control of fans and dehumidifier
- “Dead air” fans that move stagnant air toward the dehumidifier
- Energy-efficient moisture management
- Real-time response to changing outside conditions
ATMOX doesn’t just reduce humidity — it thinks, optimizing airflow and moisture control to keep your crawlspace healthy year-round.
What Sets Our Crawlspace Moisture Control Apart.
Most competitors skip the hardest part — fixing the actual water problem. They lay a vapor barrier and hope for the best.
We locate and remove the source of moisture first, whether that’s groundwater seepage, standing water, or outside penetration. Then we install a complete system designed for long-term performance.
