Late Sunday night we had an emergency leak, where we were forced to shut off water to entire house. I reach out MT Dunn plumbing and in a short notice and within 35 mins Irich was able to come over and fixed our leak. Truly appreciate the quick response especially being late Sunday night around 9-10pm!!!

We inadvertently discovered our kitchen and washing machine drains were disconnected and dumping water underneath the house, in the crawlspace. We may never know why or for how long but Irich responded to my call personally and set a date within a single business day knowing we'd couldn't use the kitchen until it was fixed. He was here on time and had it repaired in a half day. Proper invoicing and estimates based on labor and parts always makes me happy. So glad to have a plumber now. I won't go anywhere else.

Irich is very easy to work with and always shows up on time. He’s honest, professional, and very efficient. His work is fast but never rushed. He does things the right way and never cuts corners. Over the past three years, he has helped us three times: installing a water heater, replacing some toilet parts, and installing a new toilet. Every job was done quickly and professionally. He’s also very respectful of our home and keeps things clean while working. On top of that, he’s a genuinely kind person—even great with our dog 🐶 His pricing is fair and he never overcharges. It’s hard to find someone this trustworthy. I highly recommend him. Thank you Irich!

I've had MT Dunn plumbing handle a couple of plumbing issues we've had over the last few years. Our most recent visit was due to a leaking valve going to our guest bathroom toilet. It was stripped and Irich was able to fix it in short order. Friendly, transparent, punctual, and knowledgeable. We highly recommend Dunn plumbing and Mikes son Irich.

This is the second time I’ve used M T Dunn Plumbing and both experiences have been great. I recently discovered I had a leaky pipe underneath my cement driveway. M T Dunn came out and assessed the situation and gave me multiple ways get it fixed with varying costs. I decided what I wanted to do and they came out a few days later and took care of it. They cut a hole in the cement, found the leak, fixed it and patched the driveway in a single day which will end up saving me a ton of money. They’re very fair and have gotten things done quickly and easily both times I’ve needed them.

What Is Our Sewer Line Repair Process at MT Dunn Plumbing?

We follow a structured, transparent process designed to fix the problem right the first time.

1

Listening to Your Concerns

Every job starts with a conversation. We ask about symptoms, timing, and any past sewer issues so we understand the full picture before touching a single pipe.

2

Camera Diagnosis of the Line

Before recommending any repair, our technicians run a camera through the line to confirm the exact location, cause, and severity of the damage.

3

Reviewing Repair Options With You

We walk you through the findings in plain language and explain which repair method fits your situation, whether that’s a spot repair, pipe lining, pipe bursting, or full replacement.

4

Preparing the Work Site

Our crew sets up access points carefully, protecting nearby landscaping, walkways, and structures before any excavation or trenchless work begins.

5

Removing or Bypassing the Damaged Section

Depending on the chosen method, we either excavate the damaged section or use trenchless equipment to bypass digging almost entirely.

6

Installing New or Lined Pipe

We install durable replacement pipe or cure-in-place lining, sealing off cracks, root intrusion points, and weak joints for good.

7

Pressure and Flow Testing

Once repairs are complete, we test the line to confirm proper flow, watertight seals, and correct slope throughout the repaired section.

8

Restoring the Work Area

Any disturbed soil, sod, or paving is restored as closely as possible to its original condition before we leave the property.

9

Final Walkthrough With the Homeowner

We review the completed repair with you, answer any remaining questions, and confirm you’re satisfied before closing out the job.

10

Providing Documentation for Your Records

You’ll receive a written summary of the repair performed, materials used, and warranty details for future reference.

Most standard sewer line repairs in Hillsboro are completed within a single day, though larger replacements may take longer depending on scope.

When Should You Schedule Sewer Line Repair in Hillsboro?

Sewer damage doesn’t always announce itself loudly. Watch for:

What Causes Sewer Line Damage in Hillsboro Homes?

Several factors commonly lead to sewer line failure, including:

Is It Better to Repair or Fully Replace a Sewer Line?

From what we’ve seen, the answer is: it depends on the extent of the damage. At MT Dunn Plumbing, we’ve learned that the right call almost always comes down to what our camera inspection actually reveals, not what’s easiest to sell.

Here's why we feel so strongly about this:

Not every damaged sewer line needs full replacement. A general homeowner assumes the worst the moment they hear “sewer problem,” but in reality, many issues are isolated, a single cracked joint, a short section affected by root intrusion, or a localized blockage. In cases like these, a targeted repair or pipe lining is often enough to solve the problem for years to come, and pushing for a full replacement would be an unnecessary expense.

We’ve walked into jobs where the pipe showed widespread deterioration, multiple collapsed sections, or damage running the entire length of the line. In cases like these, patch repairs are little more than a temporary fix, and new failures tend to surface nearby not long after. When a line is nearing the end of its lifespan, investing in a full replacement often makes far better financial sense than paying for repeated repairs down the road.

Our opinion is simple: the scope of the job should be dictated by evidence, not by what generates the biggest invoice.

The cost of an honest recommendation is minor compared to the frustration and expense of repairs that don’t hold. We think of our camera inspection as the deciding factor, you’re not just diagnosing a pipe, you’re protecting your budget, your property, and your peace of mind.

Severely aged or already-patched systems deserve this extra scrutiny. Older clay or cast iron pipes, a history of prior repairs, and mature tree roots nearby are common conditions that tip the scale toward replacement being the smarter long-term choice.

Bottom line from our team:

If you’re serious about solving the problem for good, let the camera footage decide, not the sales pitch. We’d rather recommend a smaller repair when that’s genuinely all you need, and be upfront with you when full replacement is truly the better investment.

How Do We Decide Between Trenchless and Traditional Sewer Line Repair?

Understanding your repair options helps you make a confident, informed decision.

FactorTrenchless RepairTraditional Excavation
Yard DisruptionMinimal digging, small access points onlyFull trench dug along the pipe's path
Project TimelineOften completed in a single dayCan extend several days depending on scope
Landscaping ImpactPreserves lawns, gardens, and hardscapingFrequently damages plants, pavers, and driveways
Overall CostCompetitive once restoration costs are factored inRestoration and labor often raise total cost
Pipe AccessWorks through existing entry pointsRequires open trenches for full pipe access
Best Suited ForLocalized cracks, root intrusion, minor misalignmentSevere collapse or extensive multi-section damage
Noise and MessComparatively quiet and containedHeavier equipment, more visible disruption
Long-Term DurabilityLining and bursting materials rated for decades of useDepends heavily on new pipe material and installation

Both methods have their place, and our team will recommend whichever approach best fits your pipe’s condition and your budget.
