Spray foam insulation is a premium product that prevents air leakage in homes and commercial buildings, increasing energy efficiency and helping to lower heating and cooling costs. It’s an excellent choice for new construction and retrofits because it creates a tight seal in attics, crawl spaces, basements, rim joists and walls. It is sprayed in place and expands to fill nooks and crannies that would be difficult to insulate with fiberglass batts or cellulose.
Homeowners and builders often ask whether spray foam can be installed in existing walls. The answer depends on a number of factors. First, the condition of the walls must be good. If the walls are cracked, peeling or crumbling, a professional will need to take down and replace drywall before applying spray foam. This can be time-consuming and expensive, and it’s important to have the work done correctly to ensure that spray foam adheres to the wall and is not blown away by infiltration.

Second, the structure must have enough ventilation to ensure adequate indoor air quality. This is important because a tightly sealed home can experience a buildup of moisture inside the walls, which can lead to mold and mildew growth and increase humidity levels in the living space. This can be mitigated by installing an energy recovery ventilation or heat recovery ventilator (ERV / HRV) system.
If you have a home with sufficient ventilation, then spray foam can be installed in the walls of an existing house or commercial building during the rough-in stage. The process is similar to drywall installation and can be completed quickly by a qualified installer. It’s best to hire a professional, though, because the chemicals in spray foam are hazardous and should be handled by trained professionals using appropriate safety equipment.
