At Trenchless Innovations, we pride ourselves on offering expert air duct & sewer repair services, as well as air duct and sewer video inspections to the residents and businesses of Hanover Park, IL and the surrounding areas.

There are several clues that can tell you that your underground ducts need lining. Symptoms such as hearing a swishing sound in your heating vents, seeing increased dust or sand floating in your home or noticing reduced airflow in rooms of your home are only a few issues that can point to a problem with your underground air ducts.

Sealing underground ductwork seals ducts directly through the heating registers with a liquid, rubberized liner. Once the liner is cured, cracks in the broken duct pipes are covered, preventing dirt, debris and other contaminants from entering the air inside your home.

For more information on what is involved in the process, contact us online now to talk with one of our professional staff members.

There are many benefits of trenchless sewer repair, the main ones being complete restoration of your deteriorated ducts to a brand new condition, elimination of restoration work commonly found with traditional repair methods and a more efficient HVAC system and cleaner air in your home.

Our reviews speak for themselves! Read our customer reviews to see why our customers in Hanover Park, IL are continually satisfied with our services.

Ductwork video inspection service call. Televised ducts under slab floor. Ducts are concrete ducts possibly transite with metal fittings. Duct run in living room ion front of house is lower than all others in the house and gets water during times of rain. Suggest extending downspouts first but if that does not solve the problem a sump pit and pump should be installed in the garage and discharge out front or side of garage. Once water is resolved the ducts should be spray lied with Duct Armor duct lining material.

Televised ducts under slab floor. Ducts are concrete possibly Transite with asbestos with metal fittings and connections that are heavily rusted. There was standing water in the line in the back of the house. All downspouts need to be extended away from the house to help reduce water level. The back patio is also cracked and pitching towards the house. There is also room wher the ground against the house could be raised and pitched away from the house. After water issue is resolved the ducts should be spin cast mortared and spray lined with Duct Armor duct lining material.
