Televised ducts under slab floor. Ducts are galvanized metal and look in good condition at this time. There are sewer flies in the system but the depths of the sewer and the ducts means there is no water getting into the ducts. Televised sewer from outside clean out and see holes in bottom of pipe. Wil provide proposal for lining sewer.

I applied a second coat of Duct Armor to all underground ductwork and register vents. This reinforced the internal lining of the ducts, sealing any small leaks and preventing further corrosion. The Duct Armor coating helps improve air quality and ensures the longevity of the duct system by providing a protective barrier against moisture and debris buildup. The system is now better equipped for efficient airflow and improved indoor air quality.

Cleaned all duct runs then appplied first coat of Duct Armor to all duct runs and registers.

Descaled and flushed 2”&4” cast line from 6” outside clean out and 2” clean out under kitchen sink. 2” pipe channeled bottom missing for 15’, 4” cast about 60’ to new pvc. Giving estimate to open floor in kitchen where new pvc was installed for access to clean 4” & 2” cast and line/ epoxy coat from 2” kitchen sink 75’ to 4” cast to 6” pvc near outside clean out.

Televised ducts under slab floor. Ducts are pvc and are getting eater in the plenum area. The water is from the kitchen sink line that is channeled and missing pipe on the bottom. Provide quote for lining kitchen sink line out to main clean out outside.

Televised ducts under slab floor. Ducts are concrete possibly asbestos ducts. Metal fittings are in good condition. Will provide a proposal for spray lining ducts to encapsulate the concrete pipes.

We are applying the first application of our rubberized duct lining material to all of the heavily rusted underground duct work.
Bob S.
Customer was experiencing no or little air flow in the upstairs master bedroom and bathroom. Used our video camera to inspect the ducts. Found and identified a piece of wood in one of the registers in the bedroom. Located the ducts in the basement and found that two of the ducts had closed bumpers that were hidden behind the drop ceiling. Opened dampers and all airflow was retired to the rooms.

We are applying the second application of our rubberized duct lining material to all of the deteriorated underground duct work. The air ducts will be completely sealed and dust and debris will no longer blow out of the air vents.

Customer was experiencing sand a debris blowing out of their air vents. We are going to apply two applications of our rubberized duct lining material to completely encapsulate the air ducts. Sand and debris will no longer blow out of the air vents.

We are cleaning the underground duct work and applying our duct lining product to the entire underground duct work.

Televised ducts under slab floor. Ducts are spiral wound metal. There are ants coming in through the joints in the ducts and also in the plenum that is extremely rusted and deteriorated. Suggest rebuilding the plenum and registers and then spray lining g the ducts with Duct Armor duct lining material in order to seal the joints.
Kevin W.
Cleaned and spray lined all underground air ducts. Air ducts contained mold from the groundwater inside the ducts.

Video inspection of under slab air ducts. Ducts are spiral wound ducts and are extremely rusted and deteriorated. Suggest restoring structure back to ducts by Trenchless Casting a new concrete duct inside the old ducts. Once the structure is restored then the ducts can be spray lined with Duct Armor to provide a clean healthy breathing environment.

Video inspection of underground air ducts. Ducts are rusting and deteriorated. Sump pump does not appear to be operating. Need to replace sump pit then spray line ducts with Duct Armor Duct lining material.

We televised a third property with underground duct work for the same customer only to find the duct work was just as bad as the others, this entire system was all metal piping underground that had rusted out completely so we applied our spin cast mortar through the entire system to restructure the metal pipe and applied two applications of the duct armor product to seal the system leaving a clean air flow with no dust or odor from underground ducts!

We televised some underground duct work for a customer finding that the pipe was all PVC but the pipe connectors, register boots, and plenum box were all metal and heavily rusted out, so we applied spin cast mortar to restructure the weak rusted metal, rebuilt the register boots and plenum box, finally we applied two applications of the duct armor product to leave an nice clean and sealed HVAC system underground for the fresh air to flow through.
