During our complimentary inspection at a homeowner's residence in Brielle, NJ, we discovered a significant issue with the exterior of the house. The cantilever leaks, resulting in condensation and allowing cold air to infiltrate the house and seep under the floor. Additionally, the insulation is insufficient and fails to block airflow.
Solution
Our crew can address this issue in various ways, tailored to the cantilever's composition and structure. One effective option is to remove the siding and drill holes for dense-packing with TruSoft cellulose insulation, thereby effectively insulating the cantilever. Alternatively, we may remove the bottom wood, replace old insulation, and use techniques like spray foaming or SilverGlo foam to block air infiltration. These methods enhance comfort and energy efficiency by preventing air infiltration.
An inadequately insulated exterior cantilever can lead to condensation and allow cold air to enter the house, potentially seeping under the floors.
Highlighted in orange is the cantilever or bump out. Below the cantilever lies the basement or crawl space. To properly insulate the cantilever, we can remove some of the siding and drill holes into the side of the house between the cantilever bays, then dense pack them with TruSoft insulation.
Displaying the area beneath the cantilever where air is infiltrating the house.
Highlighted in orange is a piece of wood that lacks proper air sealing and is experiencing dry rot, thus failing to protect the house from air infiltration.
Depending on the circumstances, we may opt to either retain or replace the wood. If the wood is in good condition, we can use ZypFoam sealant to seal its seams and then dense pack the cantilever through the drill holes in the siding.
Highlighted in orange is the piece of wood that we can replace. After removing the wood, we can then clear out all the old insulation within the cantilever and employ techniques such as spray foaming or applying SilverGlo foam to effectively block air infiltration. Once completed, we can secure a new piece of wood underneath the cantilever.
