Crawl Space Repair & Encapsulation in Duluth, GA
If your home in Duluth has a crawl space, managing moisture beneath your house is essential to protecting its structure and indoor air quality. Gwinnett County’s dense clay soil, frequent rainstorms, and long humid seasons create ideal conditions for crawl space dampness and water intrusion.
At Schmitt Waterproofing, we provide crawl space repair, moisture management systems, encapsulation, interior drainage solutions, and professional dehumidifier installation for homeowners throughout Duluth. Every system we install is customized for the specific layout and soil conditions of your property — not a one-size-fits-all approach.
Whether you’re seeing standing water, musty odors, sagging floors, mold concerns, or elevated humidity inside your home, we identify the root cause and implement a long-term solution backed by a lifetime warranty on qualifying systems.

Common Crawl Space Issues in Duluth Homes
Many homes in Duluth — particularly those built in the 1980s through early 2000s — were constructed with traditional vented crawl spaces. While once considered standard practice, vented crawl spaces in Georgia’s climate often allow moisture to accumulate rather than escape.
Open crawl spaces can allow:
- Humid outside air to enter and condense
- Rainwater runoff to collect beneath the home
- Moisture to form on floor joists and ductwork
- Mold and mildew growth
- Insulation to become damp or fall
- Structural wood deterioration
- Increased humidity inside living areas
If your crawl space smells musty, feels damp, or shows visible signs of moisture, it’s time for a professional inspection.
Crawl Space Drainage Solutions in Duluth
When water intrusion is present, proper drainage is the first priority before sealing the space.
We install interior crawl space drainage systems that capture groundwater and direct it into a sealed sump basin. A high-performance sump pump then discharges the water safely away from the foundation.
Our drainage systems may include:
- Interior perimeter collection piping
- Gravel or drainage mat channels
- Sealed sump basin with airtight lid
- 1/3 HP primary sump pump
- Check valve and discharge assembly
- Underground discharge outlet with freeze protection
Each system is engineered around your home’s grading, water patterns, and soil conditions in Duluth.
Crawl Space Encapsulation in Duluth, GA
Once water is properly managed, encapsulation creates a controlled environment beneath your home and helps prevent ongoing moisture damage.
Our crawl space encapsulation systems include:
- Heavy-duty 12-mil, 20-mil, or reinforced vapor barrier options
- Complete ground coverage with sealed seams
- Wall vapor barrier installation
- Vent sealing to limit outside air intrusion
- Mechanical fastening and proper terminations
- Optional insulation enhancements
Unlike thin plastic sheeting loosely placed under homes, our encapsulation systems are professionally installed and sealed to create a durable moisture barrier.
Encapsulation helps:
- Improve indoor air quality
- Reduce mold risk
- Lower crawl space humidity
- Protect framing and subfloor
- Improve energy efficiency
- Eliminate musty odors
For many Duluth homeowners, encapsulation transforms a damp crawl space into a dry, protected foundation system.
Professional Crawl Space Dehumidifiers
Because humidity levels in Duluth often exceed 70% during much of the year, encapsulation alone may not fully control moisture.
We install professional-grade crawl space dehumidifiers such as the Aprilaire E070 system. These systems are designed specifically for below-grade environments and integrate directly into sealed crawl spaces.
Features may include:
- Automatic humidity monitoring
- High-capacity moisture removal
- Integrated condensate discharge
- Suspension (hang kit) installation
- Sealed system integration
A properly sized dehumidifier typically maintains humidity between 50–55%, helping protect wood framing and reduce the likelihood of mold growth long-term.
Signs You May Need Crawl Space Repair in Duluth
You may benefit from crawl space services if you notice:
- Persistent musty odors indoors
- Hardwood floors that cup or buckle
- Elevated indoor humidity
- Soft or uneven floors
- Visible mold
- Wet or sagging insulation
- Standing water beneath the home
- Rising utility costs
Many homeowners are unaware that air from the crawl space can circulate into the living space above. Moisture below your home can directly impact the air your family breathes.
