Spray Foaming Rim Joists in Queenstown, MD

A rim joist is a board that caps off the floor joist and forms the outer box of the floor assembly. Without the proper insulation or air sealing of the rim joist could result in condensation and higher fuel and electric bills. More than 30% of air 

This is what one homeowner in Queenstown, MD were experiencing. Living with cold floors and a increase in cost of home ownership, they went online and found Dr. Energy Saver. 

Our In Home Comfort Specialist then came out and inspected their crawl space and noticed that not only were the rim joist not insulated, but had noticed microbial growth had started forming. The rim joist were sweating from the hot/humid temperatures inside the crawl space causing this growth.

Immediately, the homeowners were very concerned about the microbial growth and also their cold floors and scheduled the project. Our production team then came in and spray foamed each rim joist. This reduces heat loss and infiltration of cold air by sealing and insulating the joist and also getting rid of the microbial growth!
