Bob was knowledgeable and thorough. No sales hype, rather Bob gave me a thoughtful explanation of my duct system and his recommendations.

Underground air ducts video inspection service visit. Televised ducts under slab floor. Ducts are a combination of concrete and also spiral wound galvanized. Will provide proposal for spray lining ducts.
Applied epoxy coating to interior of residential water pipes in Northbrook. System comprised of aging copper pipes showing signs of corrosion. Thoroughly cleaned all pipes using air scouring technique. Dried system completely before application. Applied two-part food-grade epoxy coating throughout entire system (approximately 210 linear feet). Performed pressure test post-curing - holding at 85 PSI with no drops. Water quality testing shows significant improvement. 5-year warranty provided on coating integrity.
Performed trenchless sewer line rehabilitation for residential property in Northbrook. Initial video inspection had identified multiple fractures and joint separations in original clay pipe installed circa 1965. Rehabilitation utilized CIPP (Cured-In-Place-Pipe) technology with epoxy-saturated felt liner designed for 75+ year service life. Project preparation included establishing proper bypass pumping system to maintain sewer service during installation. Thoroughly cleaned existing 4-inch pipe using combination high-pressure water jetting and mechanical cutting to remove all roots and debris. Installed 82 feet of liner from basement cleanout to municipal connection point. Utilized controlled steam curing process maintaining precise temperature gradient to ensure optimal resin curing. Post-installation video inspection confirmed successful liner deployment with particular attention to reinstatement of lateral connections. Final results show uniform liner with no anomalies and proper fl
Televised air ducts under slab portion of house. Ducts are concrete ducts with metal fittings and connections. All metal looks good at this time. Will provide a proposal for spray lining to encapsulate the concrete pipes.
Cleaned all underground duct work. Rebuilt all registers with hydraulic cement. Cut access in supply and return ducts in basement to gain access to spray. Encapsulated all underground duct work with duct armor. Installed a metal plate over the access points where we cut metal. 1/22/25 Applied second application of duct armor to all underground ductwork and register vents.
Televised ducts under slab portion of house. Ducts are concrete possibly Transite with metal connections. Metal looks good. Will provide a quote for spray lining ducts with Duct Armor duct lining material for radon and asbestos issues.
Cleaned sewer line downstream and upstream in preparation for sewer lining. Installed a 6” patch liner downstream over void in clay tile pipe. 11-14-24 Inserted a 6” liner through the existing outside clean-out extending approximately 64 feet downstream to just before the tee connection to the private main coming from the neighbors house to the west. Inserted a 4-6” liner upstream extending approximately 34' to the house just before elbow at base of stack.
Televised sewer from outside clean out in driveway 39 ft to cast to clay and then 70ft downstream. It appears that the sewer connects to the Metropolitan sewer via a drop connection into the manhole near the street. It looks like when the manhole was repaired and epoxy coated that they sealed off the tee portion that is for cleaning purposes that connects into the side of the manhole. Light is visible when the camera is pushed out and we can see that the water is flowing towards the tee that would drop down outside the manhole. Will revise quote for lining and then resend it back to customer.
Client asked for an estimate for a sewer lining project in Northbrook, IL. Sewer lining is a no-dig solution to repair and reinforce old pipes by creating a new, durable pipe inside the existing one. This method involves inserting a resin-coated liner into the pipe, which hardens to seal cracks, prevent root growth, and smooth out rough surfaces, improving flow and extending the pipe's lifespan. To line approximately 115 feet of sewer, the ballpark estimate was delivered to the client this morning.
Televised ducts under slab floor. Ducts are concrete ducts with metal fittings that are rusted and deteriorated. Some of the system has been abandoned and blocked off from the plenum, but the area in the dining room and kitchen are still active on this system below ground. Suggest spin cast mortaring metal fittings on the section that is still active, then spray lining the system with Duct Armor duct lining material to encapsulate the concrete pipes..
Cut access openings in the supply ducts in the basement. Cleaned all duct runs then applied first coat of Duct Armor to all duct runs and registers.
Televised duct to see if rocks were removed, but rock are still in the area where the kitchen elbows down to the living room. Spoke to homeowner who had not received the latest proposal from the contractor. She talked to contractor and he forwarded the proposal so she is able to see what it entails and what the cost is. She will be deciding next step. Informed her that if we are unable to clear rock that we would need to open floor under hardwood.
Televised ducts under slab floor. Ducts are pvc ducts with metal fittings that are very rusted. There is one location near kitchen and living room where there is a double turn making an elevation change where the stone is coming in from outside the pipe. Will attempt to clean and repair but that area may need to be excavated if it cannot be cleared and patched. After that the metal should be spin cast then the entire system spray lined with Duct Atmor duct lining material.
Applied trenchless sectional point repair to restore a leaking section of a cast iron drain line. Accessed the compromised area, prepped the interior surface, then pulled a polyester resin-saturated sleeve into the pipe which formed a new seamless pipe segment once cured in place.
