What is the Local Average Precipitation in Portsmouth?

Feb 12, 2024

Whether it’s in the form of rain or snow, Portsmouth residents are no strangers to high amounts of precipitation every year. In Rescon Basement Solutions’ latest blog post, we’ll discuss the average annual precipitation of the area, how it can affect your home, and preventative solutions you can utilize to keep your home safe and secure.


Portsmouth, NH Average Precipitation

The Northeast has a reputation for being one of the wetter regions in the United States, and Portsmouth is no exception.

The Portsmouth, NH area receives roughly 50 inches of rain and 53 inches of snow each year. The precipitation throughout the year is distributed fairly evenly, with slightly higher levels during the summer months. 

The US, on the other hand, receives about 38 inches of rain and 28 inches of snow on average each year. The precipitation in Portsmouth, NH is higher than the national average, so local homeowners must take the proper precautions to keep their homes safe from potential water damage.


How the Local Precipitation Can Affect Your Home

Areas with higher amounts of precipitation can experience moisture-related issues. Here are some key considerations:

  • Foundation Integrity: Excessive rainfall and snowmelt can lead to soil saturation, posing a risk to the foundation of your home. Proper drainage systems, including gutters and downspouts, are essential to redirect water away from the foundation and prevent potential damage.
  • Basement Flooding: Heavy precipitation increases the risk of basement flooding. Waterproofing measures, such as sump pumps and well-maintained seals, are essential to protect against water intrusion. Regular inspections can help identify and address potential vulnerabilities.
  • Mold and Mildew Prevention: High humidity resulting from frequent precipitation can create an environment conducive to mold and mildew growth. Ventilation and utilizing moisture control measures, like dehumidifiers, are essential to prevent these issues.


Basement and Foundation Waterproofing Methods for Portsmouth Homes

Taking precautionary measures can prevent serious and expensive damage from ever occurring in the first place. At Rescon Basement Solutions, we recommend the following waterproofing methods for Portsmouth area homeowners:

  • Humidity Control Solutions: High humidity levels can create an environment conducive to mold and mildew growth. Installing humidity control solutions, such as dehumidifiers, helps maintain optimal indoor humidity levels, preventing potential damage and ensuring a healthier living environment.
  • Sump Pumps: Basements are particularly vulnerable to flooding, especially during periods of heavy rainfall or snowmelt. Sump pumps are installed in basements and are designed to remove excess water, preventing basement flooding. Properly installed sump pumps can provide an added layer of protection against water intrusion.
  • Vapor Barriers: Vapor barriers are instrumental in preventing moisture from infiltrating your home’s foundation. By installing vapor barriers in key areas, such as crawlspaces and basements, you create a barrier that inhibits the passage of water vapor. This helps protect against potential structural damage and the development of mold and mildew.
  • Crawlspace Encapsulation: Crawlspace encapsulation involves sealing the crawlspace area to prevent moisture from entering. This comprehensive approach not only helps control humidity levels but also safeguards against issues like wood rot and mold growth. By encapsulating your crawlspace, you create a controlled environment that contributes to the overall health of your home.
