Gas Line Questions — Answered

No. In Oregon, natural gas line work must be performed by a licensed contractor and permitted by the local jurisdiction. Even small mistakes — an over-tightened fitting, the wrong sealant, undersized pipe — can cause leaks, fires, or carbon monoxide poisoning. This is not a DIY job.
We start with a diagnostic visit. If the existing line is the right size, in good condition, and just has a localized leak or damaged section, we repair it. If the line is undersized for your new appliance, corroded throughout, or doesn't meet current code, replacement is the safer call. We'll walk you through the options before any work begins.
Yes. The materials and code requirements are similar, though pressure ratings and fittings differ. We handle both — just let us know which fuel you're on when you call.
Most single-appliance installations are completed in a few hours to a full day, depending on the run length and how accessible the route is. Larger jobs — extending lines through finished walls or adding multiple appliances — may take longer. We give you a clear time estimate during the quote.
Yes — Oregon requires a permit for nearly all natural gas line work, including new installations, extensions, and most repairs. We pull the permit, coordinate inspection, and make sure the work passes the first time. That paperwork is on us.
