Code-Compliant Repairs
Every repair meets current local and state gas piping codes, not just a quick patch.
Rapid Emergency Dispatch
Suspected gas leaks are treated as urgent calls, with technicians dispatched as fast as safely possible.
Quality Materials
We use approved black iron, CSST, or copper piping matched to your system's existing setup.
Pressure Testing Included
After every repair, we pressure test the line to confirm the fix holds before we leave.

Minimal Disruption
We access lines efficiently, keeping excavation and wall openings to the smallest footprint possible.
Permit Handling
MT Dunn Plumbing manages required permits and inspections so you don't have to navigate red tape.
Established Local Trust
Hillsboro homeowners have relied on our team for safe, dependable gas line service for years.
Put together, these strengths make MT Dunn Plumbing the team Hillsboro calls when gas safety is on the line.
We follow a careful, methodical process designed to keep everyone safe while resolving the issue quickly.
Every call starts with quick safety questions. If there’s an active odor or hissing sound, we walk you through immediate safety steps, such as shutting off the gas supply and ventilating the area, before a technician even arrives.
A licensed gas technician is sent to your property right away, equipped with detection tools and repair materials suited to common Hillsboro plumbing and piping configurations.
Before any diagnostic work begins, technicians confirm the gas supply is safely controlled and check that the area is ventilated and free of ignition sources.
Using calibrated gas detectors, technicians sweep fittings, joints, valves, and exposed piping to isolate the exact source of the leak, rather than guessing based on smell alone.
Where needed, we apply pressure testing or soap-bubble testing to confirm the leak location and rule out additional weak points elsewhere in the line.
Technicians examine the surrounding pipe for corrosion, age-related brittleness, or improper past repairs that could point to a larger underlying problem.
The damaged section is cut out or sealed using approved fittings, welds, or couplings appropriate to the pipe material, whether black iron, copper, or CSST.
If a section of line is too degraded to repair safely, technicians replace it entirely with new, code-approved piping rather than patching over a failing system.
Once repairs are complete, the line undergoes a final pressure test to confirm there are no remaining leaks anywhere along the system.
Technicians safely restore gas flow, relight pilot lights where applicable, and walk you through what was found and fixed in plain language.
Most standard gas leak repairs in Hillsboro are completed within one to three hours, though larger line replacements may take longer depending on access and scope.
Contact us immediately if you notice any of the following:
If you smell gas strongly, leave the property immediately, avoid switches or flames, and call from outside before contacting us.
Beyond the obvious leak, a full inspection often reveals:
From what we’ve seen, it depends on the pipe’s condition, but we’ll always tell you honestly rather than push the bigger job. At MT Dunn Plumbing, we’ve seen how a straightforward answer to this question saves Hillsboro homeowners from either overspending or underinvesting in their gas system.
A single, isolated leak on an otherwise sound gas line usually doesn’t require a full replacement, a targeted repair at the affected fitting or section is often all that’s needed to fix the problem safely and permanently. A homeowner might assume any gas leak means the whole system is compromised, but that’s not always the case, and jumping straight to full replacement can mean spending money that wasn’t actually necessary. That’s an important distinction, and time and again, it’s exactly why we inspect the full line before recommending anything.
We’ve found leaks on newer, well-maintained systems where a single fitting repair solved the issue completely, and we’ve also found leaks on older galvanized lines where the leak was really just the first visible sign of pipe-wide corrosion. In almost every case, the condition of the rest of the line, not just the leak itself, is what actually determines the right call.
The cost difference between a repair and a replacement is significant, so we take it seriously before ever pointing a homeowner toward the bigger, more expensive option. We think of the inspection as the deciding factor, you’re not just paying for a fix, you’re paying for the right fix based on what your gas line can actually handle going forward.
Older Hillsboro homes, in particular, are where this judgment call matters most. Original galvanized piping paired with a single leak is often a sign that replacement makes more sense than repair, while a leak on newer piping usually doesn’t warrant that same conclusion.
The right answer here isn’t the same for every home, and it shouldn’t be. Our team inspects the full line before recommending anything, because the goal is always the right fix, not the most expensive one.
