We had an issue with our heating vents which had rusted due to water issues, they came explained the process to which needed to done to resolve the issue. They were professional, efficient and clean after every process.
Customer is getting water in their air ducts and plenum box (area under furnace). We are installing a perforated sump pump pit in the garage next to the furnace. We are going to tunnel under the bottom of the furnace and install a section of perforated pipe to capture the ground water. The water will get discharged out the side of the house.
Televised underground duct work found the metal was heavily rusted and weak, the ducts have had ground water enter the system many times in the past, since then the customer has had drainage work done to divert water around the house instead of entering the duct work. With the water issue resolved we were able to trenchless cast the system giving the weak metal good structure again! Now with good structure we applied our duct armor product to completely seal the system leaving a clean air flow.
