Professionally encapsulated and clean crawl space

What Does Crawl Space Encapsulation Do?

Crawl space encapsulation is an effective way to protect your home from moisture and other potential issues. One of the most important steps in this process is installing a vapor barrier, which is a thick sheet that covers the floor and walls of your crawl space to block moisture from the ground.

In addition, sealing the crawl space is crucial. This involves closing off any cracks, gaps, or openings to prevent outside air and water from entering. Together, these steps help keep your crawl space dry, reduce humidity, and protect your home from mold, wood rot, and other long-term damage. Don’t wait until moisture and mold become a bigger problem. Reach out to us at Northeast Basement Solutions to schedule your crawl space encapsulation today!

Eric Turer

Brentwood, NH

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

Jenn Miller

Lowell, MA

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!

Cheryl Edwards

Tewksbury, MA

...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!
