Every project follows the same clear, step-by-step approach, so nothing is left to chance.
We begin by talking with you about symptoms, past backups, property history, or your plans for new construction.
For repairs, we run a camera through the line to pinpoint the damage. For new installations, we evaluate the route, depth, slope, and connection points.
We explain our findings plainly and recommend the right approach, whether that’s a spot repair, lining, pipe bursting, a full replacement, or a new line.
We handle the required permits and make sure underground utilities are located before any digging begins.
Access points are planned carefully, and nearby landscaping, walkways, and structures are protected.
Depending on the method, we dig only what’s needed or use trenchless equipment to keep disruption low.
We place a new pipe, cure-in-place lining, or a fresh line at the correct depth and grade, with properly sealed joints.
We confirm watertight seals, correct slope, and smooth flow before anything is covered.
Soil, sod, and paving are returned as close to their original condition as possible.
We review the finished work with you and provide documentation covering the work performed, materials used, and warranty terms.
Most standard repairs wrap up in a single day, while full replacements and new installations may take longer depending on length, depth, and site conditions.
Speed matters, but never at the cost of quality or safety. Here’s how we keep both in balance.
Our aim is a sewer system that flows reliably and keeps your property safe.
Sewer trouble often starts quietly. Call us if you notice any of the following:
Most failures trace back to a handful of common causes:
From what we’ve seen, the answer is a firm yes in most cases, and it’s usually our first recommendation. At M T Dunn Plumbing, we’ve seen how trenchless repair protects the mature landscaping and finished hardscaping that make older Hillsboro properties so valuable in the first place.
Older Hillsboro neighborhoods often sit on established lots with mature trees, finished landscaping, and driveways or patios that homeowners don’t want disturbed. A traditional repair might assume the only path to a fixed pipe is digging straight through everything above it, but trenchless methods let us fix the pipe from the inside out, accessed through a small entry point, without tearing out everything built above the line. That’s a significant advantage, and time and again, it’s exactly why we lead with this option on older properties.
We’ve evaluated plenty of aging sewer lines where trenchless repair solved the problem completely while leaving the yard, driveway, and landscaping untouched. In almost every case, homeowners were relieved to learn they didn’t have to choose between a working sewer line and the property improvements they’d invested in over the years.
The value of an honest recommendation is significant, since trenchless isn’t the right fit for every situation. Severely collapsed sections, extreme bellies, or lines with major misalignment sometimes still require traditional excavation to get a lasting result, and we think of that honesty as the whole point, you’re not just getting a repair, you’re getting the method that actually fits your pipe’s condition.
Homes with established landscaping, mature trees, or hardscaping near the sewer line, in particular, benefit most from exploring trenchless first, since it’s precisely where the disruption of traditional excavation would be felt the most.
let the evidence guide the decision. We’d rather recommend a modest repair when that’s all you need, and tell you plainly when a new line is the smarter investment.
Knowing the differences helps you choose with confidence.
| Factor | Trenchless Method | Traditional Excavation |
|---|---|---|
| Yard Disruption | Small access pits only | Continuous trench along the pipe path |
| Timeline | Frequently finished in one day | May run several days |
| Landscaping Impact | Protects lawns, gardens, and hardscape | Often disturbs plants, pavers, and driveways |
| Total Cost | Competitive once restoration is counted | Labor and restoration can raise the total |
| Pipe Access | Uses existing entry points | Requires an open trench |
| Best Suited For | Cracks, root intrusion, minor misalignment | Collapsed lines, extensive damage, new installations |
| Mess and Noise | Quieter and more contained | Heavier equipment and more visible disruption |
| Longevity | Lining and bursting materials built to last for decades | Depends on pipe material and installation quality |
Each approach has its place, and we’ll recommend the one that suits your pipe, your property, and your budget.
