Televised ducts under slab floor. Ducts are spiral wound metal ducts and showing heavy signs of rust and deterioration. The two downspouts in the back of the house are feeding into the ground. Suggest they be moved above ground especially in winter time to avoid excess water accumulating next to the house. There is a storm sewer in front of the property that the downspouts could be run to instead of above ground or below ground. After the water issue is resolved the ducts should be spray lined with Duct Armor duct lining material.
