These homeowners in North Potomac, Maryland called our office to find ways to make their mud room more comfortable. They also asked for advice on how to make their home more energy efficient. We recommended solutions to help them achieve their goals. We made significant improvements to their basement and crawl space. This made an immediate improvement to their comfort, health and helped make the temperatures in the home more consistent. Our production crews removed damaged insulation in the crawl space to prepare for air sealing and insulation. We removed old duct wrap from the crawl space and installed a new vapor barrier. We air sealed the crawl space walls and rim and band joists with closed cell spray foam insulation. Now that the crawl space has been improved, these homeowners are finding their mud room to be more comforting and reaping benefits of improved energy efficiency.
