Crawl Space Repair & Encapsulation in Roswell, GA
Homes throughout Roswell — from established neighborhoods near Historic Roswell to properties tucked along wooded lots and creek beds — often experience crawl space moisture problems. Between Georgia’s rainfall patterns and long stretches of high humidity, unprotected crawl spaces can quickly become damp, mold-prone environments.
At Schmitt Waterproofing, we provide crawl space repair, drainage correction, encapsulation systems, and dehumidifier installation for homeowners across Roswell. Our approach focuses on long-term moisture control — not temporary fixes.
If you’re noticing standing water, musty odors, sagging floors, or rising humidity inside your home, your crawl space may be the source.

Common Crawl Space Problems in Roswell Homes
Many Roswell homes were constructed with vented crawl spaces. While once considered standard practice, vents in Georgia’s climate often allow humid air and moisture to accumulate under the home.
Over time, this can result in:
- Persistent musty odors
- Condensation on floor joists and ductwork
- Mold or mildew growth
- Wet, compressed, or fallen insulation
- Wood rot in structural framing
- Increased indoor humidity levels
- Uneven or bouncy flooring
If your crawl space feels damp or smells earthy, it’s worth having it inspected before minor moisture becomes structural damage.
Crawl Space Drainage Systems in Roswell
If water intrusion is present, proper drainage is critical before sealing the space.
We install interior crawl space drainage systems that collect groundwater and direct it into a sealed sump basin. A sump pump then safely discharges the water away from the foundation.
Drainage systems typically include:
- Interior perimeter collection piping
- Washed gravel or drainage channels
- Airtight sump basin with sealed lid
- 1/3 HP primary sump pump
- Check valve assembly
- Underground discharge line
- Freeze guard and pop-up emitter termination
Each Roswell installation is designed based on grading, soil composition, and how water moves around the property.
Crawl Space Encapsulation in Roswell, GA
After drainage is addressed, encapsulation creates a controlled environment beneath your home.
Our encapsulation systems are professionally installed and mechanically fastened — not loosely placed plastic sheets.
Encapsulation may include:
- 12-mil, 20-mil, or reinforced vapor barrier options
- Full floor coverage with sealed seams
- Wall liner installation
- Vent sealing
- Proper termination and fastening
- Optional insulation upgrades
Encapsulation benefits include:
- Reduced mold risk
- Improved indoor air quality
- Protect framing and subfloor
- Lower crawl space humidity
- Eliminate musty odors
- Improve overall energy performance
For many Roswell homeowners, encapsulation significantly improves comfort and peace of mind.
Crawl Space Dehumidifier Installation in Roswell
North Georgia humidity often requires active moisture control, even after encapsulation.
We install crawl space-specific dehumidifiers, such as the Aprilaire E070, designed to operate efficiently in sealed environments.
These systems provide:
- Automatic humidity regulation
- High-efficiency moisture removal
- Integrated condensate discharge
- Suspension (hang kit) installation
- Proper airflow configuration
Maintaining humidity between 50–55% helps protect structural wood and prevent future mold growth.
Signs You May Need Crawl Space Repair in Roswell, GA
You may need crawl space services if you notice:
- Musty odors inside the home
- Hardwood floor cupping or warping
- High humidity levels indoors
- Sagging or soft spots in floors
- Visible mold
- Damp insulation
- Water pooling beneath the house
- Increasing energy bills
Because crawl space air often circulates upward, moisture below can directly affect the air quality above.
