Replace failing sewer lines without tearing up your yard. Trenchless pipe bursting means one small hole at the house, one at the street.
We leave your lawn, landscaping, and driveway as good as we found them. Often better. It's part of the job, not an upsell.
Trusted by hundreds of Portland-area real estate agents. We scope the line, show you the footage, and give you real options
Sewer repairs don’t have to mean chaos, guesswork, or high-pressure sales tactics. For over 13 years, Black Rock Underground has handled residential, real estate, and municipal sewer work across the Portland metro and SW Washington — with fixed-price bids, clear communication, and properties left better than we found them.
Sewer problems are stressful — especially when you don’t know what’s causing the issue or how disruptive the fix will be. We handle residential sewer repair and replacement across the greater Portland metro and Southwest Washington, specializing in trenchless pipe bursting that protects your yard, driveway, and foundation.
From Hillsboro, Beaverton, and Aloha to Tigard, Lake Oswego, Oregon City, Milwaukie, Salem, and across the river into Vancouver and SW Washington — we’ve been the local trenchless specialists for over 13 years. Clear answers, fixed-price bids, and properties left better than we found them.
Most residential pipe bursting jobs are completed in a single day — often in 6 to 8 hours from arrival to cleanup. Larger or more complex lines may take two days. Compared to traditional trench-and-replace projects that can run a week or more (plus weeks of yard recovery), trenchless is dramatically faster and less disruptive.
Black Rock Underground specializes in trenchless sewer repair and replacement, including pipe bursting. These methods allow sewer lines to be repaired or replaced with less disruption to homes, landscaping, and hardscapes when conditions allow.
Trenchless solutions aren’t treated as a one-size-fits-all answer. Each property is different, and every recommendation is based on site conditions, pipe integrity, and long-term performance.
Yes. We offer personal financing for sewer repairs to make unexpected work more manageable. Financing doesn’t change the evaluation, the scope of work, or the price — it’s simply there if paying over time makes more sense for your situation.
We run a high-definition camera through your sewer line from an accessible cleanout and record the full inspection. You get detailed explanation of what we found, and written estimate with fixed pricing. Inspections are commonly used during real estate transactions, before major landscaping projects, or anytime you’ve had repeat drain issues.
Yes. We’re fully licensed, bonded, and insured in both states — Oregon CCB #196119 and Washington CCB #BLACKRU812NF. That matters if your property is in Vancouver, Battle Ground, Camas, or anywhere in SW Washington where plenty of Portland-area contractors aren’t licensed to work.
That’s exactly where trenchless pipe bursting shines. Because the process only needs one small access point at the house and one at the street, we can replace a full sewer line without tearing out concrete driveways, paver patios, mature landscaping, or established trees. In most cases, the surface above the line is untouched.
If you’ve been told you may need sewer work, it’s normal to have questions. We’re here to walk through your situation, explain your options clearly, and help you decide what makes sense for your home.
No pressure. No unnecessary work. Just honest answers from a team that puts care and craftsmanship first.
