Humid Crawl Space Encapsulated in Silver Spring, MD
Challenge
A homeowner in Silver Spring, MD contacted NV Waterproofing and Foundation Repair after noticing cold floors throughout their home and persistent musty odors coming from the crawl space. These issues are common in Montgomery County homes, often caused by excess moisture, failing insulation, and poor ventilation. Upon inspection, the homeowner also discovered that the existing insulation was falling down and there were visible water stains on the foundation walls—clear signs of moisture intrusion.
After scheduling a free crawl space inspection in Silver Spring, MD, our team confirmed that the crawl space had elevated humidity levels, water intrusion, and ineffective insulation. Without proper repair, these conditions could lead to mold growth, structural damage, and ongoing comfort issues inside the home.
Solution
To permanently resolve the problem, we installed a complete crawl space encapsulation system in Silver Spring, MD. Our team began by cleaning out the crawl space and preparing the area for installation. We then installed drainage matting to improve water flow beneath the space, followed by the CleanSpace® vapor barrier to seal out ground moisture and humidity.
To enhance insulation and energy efficiency, we installed SilverGlo™ insulation panels along the crawl space walls, helping regulate temperature and eliminate cold floors above. We also wrapped the piers, blocked off vents to prevent outside air and moisture from entering, and installed an EverLast™ crawl space door for a secure, airtight seal.
To control humidity and eliminate odors, we installed a SaniDry™ dehumidifier with a SmartDrain system, ensuring the crawl space remains dry and healthy year-round without the need for manual maintenance.
The result is a clean, dry, and energy-efficient crawl space that improves indoor air quality and comfort throughout the home. The homeowner was extremely happy with the outcome and now has a long-lasting crawl space encapsulation solution in Silver Spring, MD that protects their home for years to come.
