Crawl Space Ventilation Requirements in Portsmouth & Wenham

Crawl space is needed to have clearer indoor air at home. If there isn't any ventilation system or poor ventilation then mold might grow due to moisture and damp environment.

To ensure proper ventilation in the crawl space, you should have one square foot of screened venting for every 150 square feet of crawl space area. For instance, if your crawl space measures 30 feet by 30 feet, you'll require vents with a total square footage of 6 square feet, according to IRC.

Types of Crawl Space Vents

Standard Vents: The most basic vents are standard vents. They have simple grilles that allow air to pass easily.
Automatic Vents: These vents have humidity sensitivity that effectively maintains the optimal condition of the crawl space.
Powered Vents: These vents use electric fans to effectively maintain the airflow in the crawl space.

Vent Location and Placement

Vents should be placed in a way that should allow air to flow freely throughout the crawl space and encourage cross ventilation. The location better be near the perimeter. This will help prevent dead air zones.

Keeping Your Basement In Good Condition

Vent Covers or Sealing: Covering and sealing the crawl space is a necessary step for preventing moisture, pests, and cold air during certain seasons.
Dehumidification: Dehumidifiers are used for controlling mold humidity levels in crawl space. This can prevent mold from growing inside the crawl space.

Eric Turer

The sump pump installation was done as a first step of a larger basement remodel project. The job was done quickly, done right, and the team made sure to explain what they were doing and why at every step, including a run through of how the system worked and what to expect once it was in. I have since hired Northeast Basement Solutions to do the full project and am having the same good experience thus far. Highest recommendation

Mark and Miguel are A+ professionals! We used Northeast Basement Solutions for a foundation issue in our new home. They not only came in with a very reasonable quote, they started on the project quickly and took the time to educate us on several things we asked about. They were very responsive and communicated every step of the way. We will definitely be calling them for future waterproofing work. Thanks Northeast!

...We had a dark and moldy basement that is now a bright and clean home gym. They removed all the carpeting, moldy drywall, broken doors, old and broken ceiling lights and old and broken ceiling tiles and replaced everything with new and updated materials. They corrected some old, improperly wired electric stuff and insulated spots that were previously lacking insulation...We'll be enjoying this space as we never have before and are really thankful we were able to work with N.E. Basement!
