Moisture Barrier

The CleanSpace® Crawl Space Vapor Barrier System for Greater Washington D.C. homes

crawl space vapor barrier in Sterling installed by our contractors

A moisture barrier is the most crucial component of crawl space waterproofing.

The CleanSpace® Crawl Space Vapor Barrier is the heart and soul of the CleanSpace® system.

This durable, bright white crawl space liner installs on the walls and floors, preventing water vapor and humidity from passing through. By keeping your crawl space dry, you protect your structure and insulation from mold and rot.

With a 25-year warranty against rips and tears, this durable 20-mil poly-reinforced crawl space liner converts your crawl space into a usable storage area. And with its mold-resistant additive "UltraFresh", CleanSpace® will never support mildew or mold growth on its surface.

We make it easy to repair your wet crawl space by providing a free inspection and estimate. As Greater Washington D.C.'s trusted waterproofing contractor, we serve Arlington, Washington D.C., Alexandria and the surrounding area.

Installing your vapor barrier

The CleanSpace® Crawl Space Vapor Barrier installs quickly in your home, attaching to the walls with plastic pegs. Typical jobs take less than a day.

Benefits of crawl space encapsulation

Installing a crawl space vapor barrier is one of the most cost-effective ways to improve your home and prevent the need for future crawl space repairs.

Sealing Your Crawl Space...

  • Controls Mold & Rot
  • Save Money On Utilities
  • Keeps Away Pest/Insects
  • Passive Radon Mitigation
  • Seals Away Odors
  • Increased Comfort - No Drafty Floors
  • Increases Home Value
  • Additional Storage Space

Along with protection from mold and rot, a dry crawl space will also be inhospitable to termites, cockroaches, ants, crickets, and many other pests that need excess moisture to survive. Mice and rats are deterred by the plastic vapor barrier, and flooding waters will be kept at bay.

By sealing a crawl space, you also keep away odors and allergenic mold spores that would otherwise rise up through the floor and into your home due to the stack effect. Furthermore, this process will prevent the summer heat from entering your home and will keep the winter cold away from your furnace, water heater, and other utilities.

As an additional benefit, the CleanSpace® crawl space vapor barrier acts as a passive radon mitigation system. It is also compatible with your active radon mitigation system as well as products such as crawl space sump pumps and the SaniDry™ CX dehumidifier.

Before and After Installing Moisture Barrier
