Standard leak detection + minor repair $280-$580; section repair $580-$1,200; major scope (re-pipe section) $1,200-$3,500.

What Makes a Dedham Gas Line Repair Specific
Gas line repair in Dedham requires licensed-professional response — three reasons:
- Massachusetts licensing requirement. All gas work in MA requires a Plumbing/Gas Fitting license. Unlicensed gas repair is illegal + uninsurable + life-safety risk.
- Leak detection requires equipment. Electronic sniffer + manometer + soap test all needed for accurate detection. DIY soap-only test misses 50%+ of leaks.
- Pressure test before re-activation. After any gas line repair, line must be pressure-tested at 1.5x operating pressure + leak-checked at all joints before utility re-activation. Pro Build documents pressure test for utility records.
