Protect the crawl space and the foundation of your Dover home with a crawl space drainage system. Moisture accumulation in your crawl space can wreak havoc on the foundation of your home, and can lead to poor indoor air quality. To prevent this, we offer expert installation of crawl space drainage systems to Dover homeowners. Our systems effectively redirect water away from your crawl space, mitigating the risk of water damage and creating a healthier living environment.
With our comprehensive crawl space drainage solutions, we can:
- Install a vapor barrier to block ground moisture from entering your crawl space.
- Place a drainage mat around the perimeter to collect and direct water flow effectively.
- Install a reliable sump pump to remove collected water and prevent pooling.

Crawl space encapsulation, which is essentially wrapping or sealing the crawl space, effectively keeps away unwanted moisture from the foundation of your home. Many homes have their HVAC equipment positioned in the crawl space. And if your home in Portsmouth, Laconia, Dover, Barrington or Durham, NH is one of these, you probably have ventilation issues there. Originally, these vents were intended to boost airflow, mitigating the growth of mold. However, the vents inadvertently let in more moisture, which leads to challenges like water condensation forming on the cooling ducts. Such conditions not only decrease the energy efficiency of your HVAC unit, they also create a moist environment, which attracts insects, allows for mold growth, and can create poor indoor air quality.
The solution to excessive moisture and all the issues that come with it is crawl space encapsulation. The crawl space waterproofing experts at NH Dry Basement begin by discarding any old and worn-out plastic sheets on the ground, then carefully remove and dispose of old insulation. Our skilled team then installs vapor barriers, wall curtains, and ground liners, and ensures every crawl space vent is securely sealed from the inside. For added protection, we can even install a top-tier, energy-efficient crawl space dehumidifier.
Making your crawl space airtight and enhancing the circulation quality for your HVAC system ensures your home remains less vulnerable to pests, adds value, and increases the performance and efficiency of your HVAC unit. It can also prevent water damage, which can be detrimental to the structural integrity of your home near Dover.
