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

Televised ducts under slab floor. Ducts are concrete transite ducts with metal fittings. Will provide a proposal for spray lining ducts to encapsulate the concrete ducts.

I performed ductwork restoration services today at a residential property in Northbrook, Illinois. The scope of work included thoroughly cleaning all underground duct runs to remove built-up debris and contaminants. I also rebuilt and resealed the duct register boots where they penetrate through the floor to ensure a tight fit. After cleaning and preparation, I applied the initial coat of Duct Armor sealant to encapsulate and protect the interior duct surfaces. Duct Armor is an elastomeric coating that prevents moisture intrusion, inhibits mold growth, and improves airflow efficiency. Allowing proper curing time, a secondary coat will be applied to complete this duct sealing and rehabilitation project. Maintaining clean and properly sealed ductwork is critical for indoor air quality and HVAC system performance.

In Northbrook, IL, I successfully installed a 5-foot liner within the sewer line, terminating at the sewer main. This installation involved precise placement and curing of the liner to ensure a seamless integration with the existing infrastructure, enhancing pipe integrity and flow efficiency. The process included thorough preparation of the pipe interior and careful monitoring of the liner's adherence and function to guarantee long-term durability and effectiveness.

Televised ducts under slab floor. Ducts are concrete ducts that tested positive for asbestos. Suggest spray lining ducts with Duct Armor to encapsulate the concrete ducts.

I provided a detailed estimate for a trenchless sewer repair targeting a residential property's main sewer line. The estimate covered the costs of relining approximately 50 feet of damaged sewer pipe using a cured-in-place pipe (CIPP) method. This trenchless technique involves inserting a resin-saturated felt tube into the existing sewer line, which then hardens to form a new, seamless pipe within the old one, effectively repairing it without extensive excavation.

Precision cleaned area at connection to the city main in the 6” cast where there were heavy roots. Will provide a proposal for installing a spot repair liner in the clay and transitioning back to the cast.

Upon arrival at the customer's house, I inspected the air ducts due to uneven air distribution. Identified blocked ducts obstructed by debris, impeding airflow. Cleared the blockages and conducted tests to ensure uniform air distribution throughout the duct system.
