The co-owner of North Haven-based business has been sentenced to one year and one day in prison for his participation in bid-rigging and fraud schemes that targeted both private and public entities, according to a press release issued by the U.S. Department of Justice (DOJ).

Thomas F. Langan, co-owner of North Haven insulation contracting firm Langan Insulation, LLC, was sentenced in front of a federal judge in Bridgeport on Sept. 28. Langan Insulation was ordered to pay a $150,000 criminal fine for its role in the schemes. According to the DOJ, both defendants were also ordered to pay restitution to the victims.

According to guilty pleas entered in 2020, Langan and Langan Insulation conspired with other insulation contractors to rig bids and engage in fraud on contracts for installing insulation around pies and ducts on various construction projects including those at hospitals and universities, as well as additional private and public entities. A press release from the DOJ indicated that the conspiracy ran began as early as October 2011 and continued until May 2018, nearly seven years.

Five other individuals and companies have also pleaded guilty to criminal conduct in relation to the investigation. They await sentencing, according to a press release.

“Today’s sentences reflect the seriousness of offenses that subvert the competitive process and target public and private institutions,” said Assistant Attorney General Jonathan Kanter of the DOJ’s Antitrust Division in a written statement. “We will pursue and hold accountable executives and companies who undermine the competitive process for personal gain and corporate greed.”

Previously, Langan and Langan Insulation pleaded guilty to one count of bid rigging under Section 1 of the Sherman Antitrust Act and one count of conspiracy to commit wire fraud. Langan had been ordered to pay a $20,000 criminal fine, restitution in the amount of $480,900, and a special assessment of $200. In addition to its criminal fine, Langan Insulation was ordered to pay restitution in the amount of $480,900 and a special assessment of $800.

The case continues to be under investigation by the Antitrust Division’s New York office, the. U.S. Attorney’s Office for the District of Connecticut, the FBI’s New Haven bureau, and the Defense Criminal Investigative Service’s New Haven Resident Agency.
