The framing was replaced due to rot. The ducts serve bathroom and kitchen fans.
The job entailed a bathroom exhaust fan. Previously the fan duct terminated at the attic vent. The correction stated that the duct can't terminate within the attic. The contractor said that he would cut a hole in the attic vent and stick the end of the duct through the hole. I told him no and said to go through the roof or the wall. He stuck a foundation vent next to the attic vent and the duct terminates behind the vent.
The lid was insulated prior to any inspection. I asked that the insulation be removed. I found this abandoned fan duct. The lady that lives there was present. I wonder what she thought of the contractor after seeing this.
