Spray foam crumbling and blocking airflow
Why it happens here
Most spray foam in Maplewood homes was installed more than 15 years ago. Over time, heat cycles and humidity cause the foam to become brittle. It cracks, crumbles, and falls into the duct, where it blocks airflow and gets blown into your living space.
Our approach
We remove the foam by hand and with air whips, then scrub the duct walls with a rotary brush system. We use a negative air machine to capture everything we loosen. After cleaning, we inspect with a camera to make sure no foam remains.
