Houston insulation company, manager charged in illegal dumping case

A roadside pile of insulation material, pallets and packaging debris in north Houston has turned into felony charges for Therm-All Insulation LLC and branch manager Cierra Cano, a case that left nearby residents facing the blight, the cleanup burden and the environmental risk of illegal dumping along East 36th Street.

Investigators with the Harris County Precinct 1 Environmental Crimes Unit traced the case to a March 19, 2026 investigation in the 200 block of East 36th Street, where they said they found one of the area’s known dumping hotspots. Surveillance video allegedly showed multiple people unloading waste from a truck onto the side of the road, with a forklift moving debris off the vehicle and another person on an electric scooter appearing to keep watch.

By the time authorities documented the pile days later, they estimated it at about 1,512 cubic feet, well above the threshold for a state jail felony under Texas Health and Safety Code Section 365.012. That law makes illegal dumping a state jail felony when the waste weighs 1,000 pounds or more or has a volume of 200 cubic feet or more, and it also covers dumping at an unapproved site, including property on or within 300 feet of a public highway.

Investigators later linked the truck back to Therm-All and interviewed people at the company on April 1. Cano allegedly acknowledged that the workers were Therm-All employees and said the company was dealing with too much waste, not enough dumpster space and complaints from property management about trash buildup. FOX 26 reported the company later cleaned up the debris voluntarily and bought additional dumpsters, while Cano had not been arrested as of publication.

The case landed in a part of Harris County where illegal dumping has long been more than an eyesore. Independence Heights and nearby north Houston corridors have repeatedly dealt with complaints tied to roadside trash, vacant lots and chronic dumping sites, and county officials have warned that abandoned piles can attract rodents and mosquitoes, clog drainage and worsen flooding risks.

Harris County Precinct 1 says its Environmental Division is a county-wide investigative group that works with local officials to respond to crimes such as illegal dumping and pollution. The office’s hotline for reports is 832-927-1567. Precinct 1 said in early March that it had launched 110 illegal dumping investigations in 2026 and had led to 49 criminal charges, using a network of about 150 covert cameras to monitor chronic hotspots.

Therm-All lists its Houston location at 3556 Yale St. and says it has operated since 1981 as a national supplier of insulation solutions. The company’s footprint in Houston, and the alleged use of its workers and truck in the dumping, has made this case a test of how far county investigators can go in turning a neighborhood nuisance into a criminal enforcement action.
