External French Drain in Princeton, NJ

While the crawl space may be the least used part of the home, it makes a huge difference in the home’s environment and quality of life. To name a few, the crawl space is a big factor in a home’s indoor air quality, temperature regulation, energy costs, and overall comfort in your home. As the Jersey Shore’s leading crawl space specialists for over 20 years, we have helped thousands of our neighbors here along the shore to achieve a healthy and protected home environment through crawl space services and encapsulation. It also means that we have seen the effects that take place when a crawl space is neglected.


Our goal with these weekly before and after transformations is to show you the difference that a properly maintained crawl space can make in a home. Remember, your crawl space can look like this too! These services make a difference that you can both see and feel throughout the home. If you’re interested in updating your crawl space, take a look at this recent crawl space transformation and external French drain installation in Princeton, New Jersey:

  • This Princeton, NJ homeowner reached out to us because their crawl space has been experiencing consistent flooding after having been flooded with 5” of water after a particularly bad storm. Since that initial flood, the crawl space has been flooding with water every time it rains. Following our 22-point comprehensive evaluation, we determined that this crawl space was a great candidate for a French drain system. In addition to installing the French drain system, we performed the following services:
    • Raised the grade of the crawl space using approximately 6 tons of ⅜” pea gravel.
    • Installed 25-mil drainage matting.
    • Installed a ½ HP Zoeller sump pump.
    • Installed a 12-mil string reinforced vapor barrier to the floors, walls, & pillars.
    • Installed foam pipe insulation.
    • Installed an interior perimeter French drain in the concrete floor.
    • Installed an exterior French drain system.
