Propane, Compressed Gas & Dry Ice Supplier in Deep River, CT

Nestled in the Lower Connecticut River Valley between Chester and Essex, Deep River is a small Middlesex County town with a great sense of place. Known as part of the Tri-Town Area, the colloquial term reflects how tightly these three communities share character, commerce, and geography. The town’s 19th-century history as a center of ivory manufacturing earned it the nickname “queen of the valley,” and the Pratt, Read and Company Factory Complex on Main Street is on the National Register of Historic Places. Each third Saturday of July, Deep River hosts the Ancient Muster, the largest single-day gathering of fife and drum corps in the United States.
As a fourth-generation family business serving Connecticut since 1941, ALL-GAS is proud to support Deep River’s homeowners and businesses. With a population of about 4,400 spread across 14 square miles and a landscape shaped by river valleys, wooded hillsides, and the village of Winthrop to the west, many residential properties here sit well beyond the reach of natural gas lines. For those households and businesses, propane is the dependable, on-site energy solution they count on year-round.

Residential Propane in Deep River, CT
Deep River’s homes range from the denser housing near the town center and Deep River Center to the more spread-out properties in the western Winthrop section and along the wooded roads that run toward the Chester border. Much of the town’s residential fabric is single-family housing away from any natural gas infrastructure, where propane provides reliable heat, hot water, cooking fuel, and standby generator power that protects households when storms affect the grid along the river valley.
