Trenchless methods are Stronghold’s first choice whenever the pipe condition supports them. They are faster, less disruptive, and cost-effective for the right situations. But they are not the right answer for every situation. A pipe that has collapsed, a section that has been crushed by root or soil pressure, a line that has failed at the point where it connects to the foundation, or a run of deteriorated pipe that simply has no structural integrity remaining are all situations where trenchless patching is not a solution. Putting a liner inside a pipe that cannot support it is not a repair.
In those cases, the honest recommendation is excavation and replacement. Dig and replace is not a failure of the trenchless approach. It is the right call when the pipe condition genuinely requires it, and doing it correctly matters just as much as any other repair decision you will make about your home’s sewer system.
Stronghold Pipe Repair handles residential sewer dig and replace for homeowners across Lakeville, Apple Valley, Burnsville, Farmington, Rosemount, Prior Lake, Savage, Eagan, and the surrounding Twin Cities south metro. We excavate precisely, replace with the right pipe and fittings, restore the surface, and leave you with a sewer line that is built to perform reliably for decades.
One of the biggest benefits of drain pipe descaling is restoring the pipe’s interior diameter. When buildup is removed, wastewater can travel through the system more efficiently.
Once scale is removed, materials like grease, soap residue, and waste are less likely to accumulate inside the pipe.
Drains often empty faster, backups become less frequent, and the plumbing system works more reliably.
Removing buildup from pipes helps maintain pipe condition and may delay the need for major sewer repairs.
A pipe section that has collapsed inward has no structural integrity to support a trenchless liner. Camera inspection showing a collapsed pipe is one of the clearest indicators that excavation is the appropriate response. The collapsed section needs to come out and be replaced with new pipe bedded and backfilled correctly.
Tree roots exert pressure on pipe walls from the outside as they grow against and around the pipe. Significant soil settlement, construction activity, or heavy equipment over a shallow pipe run can all cause crushing damage that deforms the pipe cross-section beyond what a liner can bridge.
Root intrusion that has progressed to the point of structural pipe failure is beyond the reach of a point repair or a spot liner. When the pipe wall itself has been breached and the surrounding soil has begun to migrate into the pipe, the section needs to be replaced.
The point where the sewer lateral leaves the house through the foundation is a common failure location, particularly in older homes. Access for trenchless repair at this connection point is often not practical, and the consequences of a failed seal at the foundation are significant enough that excavation and a proper connection repair are the appropriate response.
When camera inspection reveals deterioration that is consistent across the full length of the run rather than isolated at specific points, full replacement is more cost-effective than addressing individual defects that will be followed by more defects as the remaining pipe continues to age.
Before any digging begins, Stronghold locates the sewer lateral and identifies every other underground utility in the excavation zone. The excavation footprint is planned to access the failed section with the smallest practical disturbance to the surrounding surface and landscaping.
We excavate to the depth and length required to access and remove the failed pipe section. Excavation is controlled to protect the surrounding soil structure and to minimize the trench width needed to work safely and complete the pipe installation correctly.
The failed pipe section is removed and the trench is inspected to confirm the pipe bed condition, identify any contributing factors like root intrusion into the trench, and verify the condition of the pipe sections on either side of the replacement zone.
Replacement pipe is installed in appropriate bedding material, connected to the existing pipe on each end with fittings appropriate to the pipe materials being joined, and sloped correctly to maintain the flow grade of the sewer lateral.
The trench is backfilled in lifts and compacted to the density required to prevent settlement over the pipe run. Improper backfill and compaction is one of the most common causes of post-replacement problems. Stronghold completes this step correctly rather than rushing through it.
The surface above the excavation is restored after backfill is complete. Depending on what was above the trench, this may include sod replacement, gravel restoration for driveway surfaces, or concrete patching. Stronghold discusses surface restoration scope during the estimate process so there are no surprises.
A successful sewer dig and replace project depends on more than excavation alone. Stronghold begins every project with camera inspection and utility locating to ensure the repair scope is based on the actual pipe condition and to protect surrounding underground infrastructure during excavation. Replacement materials are selected specifically for the pipe system, soil conditions, and burial depth rather than using generic materials that may not fit the application long term. After installation, the surface is fully restored and the completed replacement is verified with post-installation camera inspection to confirm proper alignment, flow, and connection integrity before the project is finalized.
Stronghold Pipe Repair handles residential sewer dig and replace across Lakeville and the Twin Cities south metro with honest scoping, precise excavation, correct installation, and a finished project that holds up for the long term.

Camera inspection determines this. Trenchless methods work well for cracked, root-intruded, or deteriorated pipe that still has structural integrity. Collapsed sections, crushed pipe, and severe structural failure require excavation. Stronghold reviews the inspection footage with you and explains which approach is appropriate for the condition of your specific pipe.
The excavation footprint is limited to what is necessary to safely access and replace the failed section. A typical residential sewer repair involves a trench that is roughly two feet wide and as long as the failed section requires. Stronghold keeps the footprint as small as possible while maintaining the safe working conditions and access needed to do the installation correctly.
Most residential sewer dig and replace projects are completed in one to two days depending on the length of the replacement section, the depth of the pipe, and the surface restoration required. Longer replacement runs or difficult access conditions may extend the timeline. Stronghold provides a realistic timeline during the estimate process.
PVC is the standard replacement material for residential sewer laterals in most south metro applications because of its durability, smooth interior surface, and long service life. Pipe diameter is matched to the existing system. Stronghold specifies the replacement material appropriate for your specific application during the scoping process.
Surface restoration depends on what was above the trench before excavation. Sod, gravel, and concrete surfaces are all restored as part of the project scope. Stronghold discusses surface restoration during the estimate so you know exactly what the finished project will include before any work begins.
