Propane, Compressed Gas & Dry Ice Supplier in Durham, CT

Durham is a rural community with deep agricultural roots, scenic farmland, and roughly 60 miles of public roads threading through a 23.8-square-mile landscape that has held onto its open character despite decades of suburban development pressure. The annual Durham Fair, one of Connecticut’s largest agricultural fairs, reflects just how central that farming identity is to the community. Owner-occupied housing runs at over 90 percent, a figure that speaks to the stability and investment of a population that has chosen to plant itself here. Durham’s Historic District ties the town center to its colonial past, and quiet neighborhoods along wooded roads make up the bulk of its residential fabric.
As a fourth-generation family business serving Connecticut since 1941, ALL-GAS is proud to support Durham’s homeowners and businesses. In a town this rural, with scattered residential properties, working farms, and a landscape well beyond the reach of municipal gas lines, propane isn’t a supplement to anything. It’s the primary energy source that keeps homes heated, water hot, and farms running through every Connecticut season.
