Crawl Space Encapsulation & Waterproofing in Connecticut

Crawl Space Encapsulation & Waterproofing in Hartford, Middlesex, New Haven and throughout the rest of Connecticut

Let Value Dry provide the solution for your damp, musty crawl space.

Your home is made up of many parts all working together as one system effectively maintaining air quality, temperature, and structural integrity. Air moves by way of the convection process from the basement or crawl space up through the living areas and out through the attic.

Your HVAC system circulates some of that air through the living areas. A wet or damp crawl space with insufficient air circulation affects the air quality throughout the home. Look for some warning signs to determine whether you need encapsulation.

  • Presence of Insects or Rodents
  • Open Vents in Crawl Spaces
  • Water or Wet Spots on the Floor
  • Visible Mold or Strong Smell of Mold
  • Cold Floors or Rotted Wood Above Crawl Space
  • Humid Environment that Sags Crawl Spaces

crawl space waterproofing connecticutAs a coastal northeastern state, Connecticut gets its share of wet weather. This moisture, when it enters your crawl space begins to promote mold growth and decay of the structural members of your crawl space.

You may recognize the symptoms of a wet crawl space which begin as musty odors in the house, family members suffering from allergy or asthma symptoms, or higher than normal humidity in the rooms adjacent to the crawl space.

How Water Will Enter Your Home & Effect Your Indoor Air Quality

Water may be entering your crawl space through a failed plumbing line or fixture, cracks in the foundation wall or floor, up through a dirt floor or sometimes through an improperly flashed top plate. Foundation cracks should be corrected by a skilled Connecticut foundation repair contractor, and there are some things you can do to reduce water infiltration into you crawl space.

Immediate steps you can take to minimize the water entering and affecting your crawl space:

  • Correct any plumbing leaks
  • Ensure all grading slopes away from the foundation walls
  • Ensure all gutters carry water at least 5 feet away from the foundation walls
  • Ensure air vents are open and free from obstructions blocking air flow
  • A good dehumidifier is always recommended to manage moisture in a crawl space

Waterproofing a crawl space with a dirt floor often requires encapsulation or a drainage system and encapsulation combined to solve the moisture problem.

  • Crawl space encapsulation is the installation of a heavy puncture resistant vapor barrier membrane over the dirt floor and up the walls.

Waterproofing a crawl space with a concrete floor can be effectively managed through the installation of a sump pump or a combination of a sump pump and French drain.

  • When all or part of the foundation walls are underground, a vapor barrier tied to a French drain is always recommended as the foundation walls will seep water during the Connecticut rain or snow months.

Depending on how much of the foundation wall is underground, an exterior waterproofing system may be more effective. Regardless of the method used to waterproof your crawlspace you will see, feel and smell the improvement in air quality almost immediately.
