Why Homeowners Choose Langlois

Three credentials separate us from most Chittenden County contractors:

1. Vermont Master Plumber — Jamie holds the state’s highest plumbing license. Every plumbing job is done under that license.

2. Mitsubishi Diamond Elite + Daikin Certified Dealer — both certifications require factory training and customer satisfaction performance. The dual cert means we can spec the right brand for YOUR home, not the brand we’re stuck with.

3. EPA 608 Certified Technician — federal certification required for refrigerant handling. We carry it because it’s legally required for heat pump work.

We are not the cheapest option in Chittenden County. We are the most qualified.
