Crawlspace Encapsulation in Strafford, Vermont, with Matt Clark's Northern Basement Systems

Challenge

In the picturesque town of Strafford, Vermont, a homeowner faced persistent crawlspace issues affecting their home’s overall comfort and energy efficiency. The space was damp, with evidence of water intrusion and high humidity levels. In addition, cold drafts were seeping up through the floors, making the living spaces less comfortable during the harsh Vermont winters. The homeowner was concerned about potential structural damage and high energy bills due to poor insulation. The primary challenge was to eliminate moisture and improve insulation within the crawlspace. With Strafford’s cold climate, moisture in the crawlspace could lead to many problems, including mold growth, wood rot, and an increased risk of foundation issues. The homeowner needed a solution that would address the immediate moisture problem and enhance energy efficiency and comfort in the home.

Solution

Matt Clark's Northern Basement Systems was created to design and implement a comprehensive encapsulation system. The plan involved installing a CleanSpace vapor barrier and closed-cell spray foam insulation to create a sealed, energy-efficient environment. This dual approach would protect the crawlspace from moisture intrusion and improve the home’s insulation, resulting in better temperature regulation and reduced energy costs.

Scope of Work:

1. Clearing and Preparing the Crawlspace:

   • The team began by clearing debris and old, ineffective insulation, creating a clean workspace. This step was crucial for inspecting the foundation for potential issues and preparing the crawlspace for the new installation.

2. Installing the CleanSpace Vapor Barrier:

   • A CleanSpace vapor barrier was laid over the crawlspace floor and extended up the walls. This high-quality, heavy-duty liner created a watertight seal that prevented moisture from entering the crawlspace. The barrier’s puncture-resistant and antimicrobial properties helped protect the space from mold growth and ensured long-lasting performance.

3. Applying Closed-Cell Spray Foam Insulation:

   • Closed-cell spray foam insulation was applied to the crawlspace walls and any exposed pipes and beams. This type of insulation is highly effective at creating an airtight seal and is moisture-resistant, making it ideal for a Vermont crawlspace. The insulation helped to stabilize temperatures within the crawlspace, preventing cold air from seeping into the home and reducing the energy required to heat the living spaces above.

4. Sealing Gaps and Improving Ventilation:

   • The installation team sealed any gaps and cracks in the crawlspace to ensure that the CleanSpace barrier and spray foam insulation would be as effective as possible. Proper ventilation was also added to enhance airflow, further controlling humidity and reducing the chances of condensation.

The completed encapsulation system transformed the Strafford home’s crawlspace into a clean, dry, and energy-efficient space. Combining the CleanSpace vapor barrier and closed-cell spray foam insulation successfully eliminated moisture intrusion, maintaining consistent temperatures and minimizing energy loss. The homeowner noticed an immediate improvement in the comfort of their living areas, with fewer cold drafts and reduced heating costs. The encapsulated crawlspace also protected the home's foundation against potential water damage and structural issues. The homeowner was thrilled with the outcome. They reported a marked difference in the temperature and comfort of their home and lower utility bills. Ensuring their crawlspace was protected from moisture and mold growth brought them peace of mind. The Northern Basement Systems team's professionalism and attention to detail were also highly praised.
