Excellent job
Ben - Glenview, IL 60025
We had a neglected duct that was set to structurally fail when we purchased our house last year. Bob and his team were the only ones who had a suggestion that didn't involve demo of the foundation to get to the duct. The team was able to build a support structure for the duct then apply duct armor to prevent future issues. The entire team was great with communication about the scheduling, explanation of the process, and results. I couldn't be happier. My family and I will sleep better knowing this is no longer an issue with the home.

Televised ducts under slab floor. Ducts are clay tile ducts and are being used as return ducts for the system. There are area on each duct run. Where crack in the pipe are visible and the area where the pipe meets the slab floor has large gaps. Suggest spin cast mortaring the system for structure then spray lining ducts with Duct Armor duct lining material.

Televised sewer from outside clean out oout to main and then back towards house. Pipe is scaled. Suggest changing toilets to Gerber Avalanche. Also will provide proposal for descaling cast iron.

Televised ducts under slab floor. Duct are concrete with metal fittings and connections. Will provide proposal for spray lining to encapsulate the ducts.

10-11-2024: cleaned and measured sewer in preparation for lining from 6” pvc clean out in front yard (7’5”)deep, x2 LR3 (10’X6”) x1(5’x6”) elbow at bottom of clean out can not use scope to direct liner. 10-15-2024: lined sewer from 6” pvc clean out in front yard 18’ downstream to city main starting liner just downstream of clean out and ending liner just before city main.

Tvd sewer from flood control in front yard 90’ to tee from line out house and 45’ to city main heavy root both ways.

A televised duct inspection of the ducts under the slab floor revealed that the concrete rectangular chases are separated from the floor. This gap could allow radon to enter the home, making it unsafe to use spray lining for sealing. Since the spray lining can't effectively fill the gap, we suggest rerouting the ductwork overhead to ensure proper sealing and prevent potential radon exposure.

Met inspector who approved and passed the work. Backfilled then replaced concrete. Customer paid balance of job $6,521 on invoice from yesterday. Gave waiver of lien to cleaning lady as directed by customer.

Excavated area in garage to expose 4” cast pipe that was shifted. Repiped with 4” pvc. Descaled 4” cast iron pipe and got measurements for lining. Inserted a 4-6” liner through the open pipe extending approximately 80 feet downstream ending just before the city main and starting in the 4” cast iron. 8/8/24 Inspection & backfill on different job.

Televised sewer from overhead clean out. Located broken cast in garage and see another spot before main that is very badly cracked. Provide quote for lining.

televised sewer from outside clean out. See one area downstream that has a crack in the pipe at a joint. Suggest installing a 4ft spot repair liner in the area of the crack.
Bob S.
Provided estimates for spot repair or replacing 18 feet of sewer line. Conducted a detailed inspection using a sewer camera to pinpoint the damaged areas. For spot repairs, recommended trenchless techniques using epoxy resin for targeted fixes. For a full 18-foot replacement, suggested traditional excavation or trenchless pipe bursting, depending on site conditions. Outlined the process for each option, including preparation, repair or replacement, and testing. Explained the benefits and potential challenges of each approach to ensure a thorough understanding of the solutions.

Televised ducts under slab portion of house. Ducts are concrete transite with metal fitting. Suggest spray lining ducts with Duct Armor duct lining material to encapsulate the concrete ducts.

I conducted a thorough duct inspection under the slab floor at a residence in Glenview, IL today. The ducts are concrete transite with metal fittings, which appear to be in good condition. Based on the findings, I will provide the homeowner with a proposal to spray-line the ducts as a long-term rehabilitation solution.

I performed a second application of Duct Armor to reinforce the protective coating on the interior surfaces of the ductwork. This additional coating layer enhances the durability and longevity of the ducts, providing further protection against corrosion, leaks, and contaminants for optimal HVAC system performance.

I conducted a detailed inspection of the ductwork located under the slab floor using a specialized duct camera. The ducts were identified as galvanized corrugated metal, which is prone to degradation over time. Given the concerns about Radon gas infiltration, I provided a proposal to the homeowner for spray lining the ducts with a high-grade sealant. This process involves applying a durable, airtight coating internally across all duct surfaces to encapsulate them, effectively blocking the entry of Radon gases and improving air quality. The proposal includes all material and labor costs for a comprehensive and preventive solution.

Televised ducts under slab floor. Ducts are galvanized and showing signs of rust and deterioration. May need to spin cast mortar a portion of the system then spray the entire system with Duct Armor

Televised ducts under slab floor. Ducts are clay tile ducts that have offset joints some cracks and water standing in the rear of the house where there is a dip in the pipe. Gutters need to be inspected during a rain. A swale should also be installed as well as an outside pit and pump.

Televised ducts under slab floor. Ducts are Transite ducts that appear to be in good condition. No signs of water damage or intrusion. Suggest downspouts around the hous be extended and in some areas reconfigured to lessen water accumulation next to the house. Ducts should be spray lined with Duct Armor duct lining material to encapsulate the asbestos pipe.

Televised ducts under slab floor. Ducts are cardboard ducts with metal connections and fittings. There are a couple areas where the pipe is collapsed and we cannot get through. Part of the house is already above ground ducts. Because the registers are so small we would have to open the floor in several areas. Suggest turning the remainder of the system overhead.

We are applying the second application of our rubberized duct lining material to all of the underground asbestos transite air ducts. The air ducts will be completely encapsulated and the air in the home will be safe for the customer to breathe.

Televised ducts under slab floor. Ducts are concrete ducts with metal connections and fittings. Ducts contain asbestos. Suggest spray lining the ducts with Duct Armor duct lining material in order to encapsulate the asbestos pipes.

Video inspection of underground air ducts. Ducts are clay tile ducts where the joints are allowing dirt debris and water to enter the pipes. Suggest extending downspouts and possible install an outdoor sump pit and pump to control the water. Once the water issue the ducts should be spray lined with Duct Armor duct lining material to provide a more clean and healthy breathing environment in the home.
