We are cleaning all the underground duct work, installing a 3’ spot repair liner in the main line where a breach in the pipe was allowing the gravel back fill to fall in and block air flow off for the bedrooms, and also sealing the entire underground duct work with our duct lining product.
Televised ducts under slab floor. Ducts are galvanized metal and showing slight signs of rust. No water was visible in the system at the time of inspection. Customer needs to extend downspouts away in the back of the house and also inspect gutters for proper flow. Suggest spray lining ducts with Duct Armor duct lining material.
