I worked on sealing an above-ground duct system that had multiple leaks, impacting airflow. After inspecting the ducts, I used Duct Armor to line the interior, ensuring a durable seal. This not only improved the efficiency of the system but also helped reduce energy loss. The application process was completed in stages to ensure full coverage and lasting results.
Installed four gerber avalanche toilets used existing seats. Televised sewer from the floor cleanout in the utility closet and paper tested and flushed new toilets and paper is clearing in line.
Video inspected sewer. Using toilets, flushed toilet paper multiple times and saw it wasn't getting completely flushed to the main. Installed a new Gerber Avalanche toilet to see if a more complete flush would push toilet paper out. After multiple flushes, the pipe was cleared with each flush. Providing estimate to replace 4 toilets with Gerber Avalanche.
Lined 4” cast iron sewer line from floor cleanout in janitorial closet approximately 25’ downstream. Lined 4” cast iron sewer line from men’s bathroom floor cleanout approximately 8’ downstream.

Completed trenchless lateral lining to rehabilitate a leaking sewer branch connection. Excavated a small pit at the junction, cleaned the existing pipes, and installed a T-liner impregnated with epoxy resin. Once cured, the seamless repair sealed the connection point from further infiltration without digging.
