Thompson Trenchless provides expert sewer line repair services throughout Wyandotte, Monroe, and Downriver Michigan using advanced trenchless technologies that fix damaged pipes without destroying your property. When your sewer line develops cracks, breaks, or root damage, traditional repair required excavating your entire yard—destroying landscaping, driveways, and costing $15,000-$40,000. Our trenchless repair methods fix pipes from inside, preserving your property while providing permanent solutions.
We specialize in repairing all types of sewer line damage including cracked pipes, broken sections, root intrusion, corroded cast iron, and offset joints. Using video camera inspection, we diagnose problems precisely, then repair using CIPP lining, pipe bursting, or spot repair methods—all without excavation.
Serving Wayne County and Monroe County with 30+ years experience, same-day inspections, and lifetime workmanship warranties, we’re your trusted choice for permanent sewer line repairs that last 50-100 years. Return to our drain cleaning hub to explore all our services.
Your sewer line is the pipe carrying all wastewater from your home to the municipal connection. Buried underground, it faces constant stress from soil movement, tree roots, age, and corrosion. Over time, damage develops: cracks form, sections break, roots penetrate, cast iron corrodes, and joints separate.
Sewer line damage worsens progressively. A small crack allows root entry; roots expand the crack; more roots enter; the crack becomes a break; sewage leaks into soil; eventually the line fails completely. Early repair prevents escalation and catastrophic failures requiring emergency sewer line replacement.
Traditional Sewer Repair: Excavate a continuous trench along the entire damaged section (often 50-100+ feet). Dig 4-6 feet deep through grass, landscaping, trees, driveways, sidewalks. Remove old pipe. Install new pipe. Backfill trench. Restore everything destroyed. Timeline: 1-2 weeks. Cost: $15,000-$40,000 including restoration.
Trenchless Sewer Repair: Access through small entry points (existing cleanouts or 3×3 foot pits). Insert repair liner or new pipe from inside existing line. No excavation along pipe length. Property stays intact. Timeline: 1-2 days. Cost: $5,000-$15,000. Savings: $10,000-$25,000 with equal or superior longevity.
Repair Works When: Pipe maintains basic structure (not completely collapsed), damage is isolated or limited (cracks, breaks, root damage in specific areas), pipe diameter is adequate for flow needs, pipe material can accept lining (most can).
Replacement Needed When: Pipe completely collapsed with no remaining structure, extensive damage throughout entire length (60%+ deteriorated), pipe bellied or sagging severely, diameter too small for current needs, orangeburg pipe delaminated, code compliance requires replacement.
Our video inspection determines which approach your situation requires. We always recommend repair when viable—it’s less invasive and costs less while providing comparable longevity.
Cracks develop from ground movement, settling, freeze-thaw cycles, or age. Small cracks allow root entry and sewage leakage. CIPP lining seals cracks from inside, creating seamless pipe that prevents future cracking.
Complete breaks occur from severe settling, tree root pressure, or extreme age. Broken sections lose structural integrity. We repair using CIPP lining (if structure remains) or pipe bursting (if collapsed) to restore function.
Tree roots infiltrate through joints and cracks seeking moisture. Roots create blockages and structural damage. We remove roots via rooter service, then line pipes to prevent future intrusion.
Cast iron corrosion creates channeling, holes, and wall deterioration. Hydrogen sulfide from sewage forms sulfuric acid that eats pipe walls. CIPP lining stops corrosion and adds 50-100 years life.
Pipe sections separate at joints from settling or poor installation. Offsets create snag points collecting debris and roots. Lining bridges separated joints, creating continuous seamless interior.
Severe corrosion creates channels (grooves) in cast iron bottoms where sewage concentrates. Channeling eventually perforates pipe. CIPP lining fills channels and restores smooth flow surface.
How It Works: Insert resin-saturated liner through cleanout or small pit. Position liner throughout damaged section. Inflate liner against existing pipe walls. Cure resin with hot water or steam (2-4 hours). Result: new seamless pipe inside old pipe.
Best For: Cracks, breaks, root damage, corrosion, separated joints—any damage where existing pipe maintains some structure. Most common repair method.
Advantages: No excavation, repairs entire section in one installation (up to 600+ feet), seamless design prevents future roots, 50-100 year lifespan, works for all pipe materials, costs 50-70% less than traditional.
Timeline: 1-2 days including curing. Operational same day after final connections.
How It Works: Insert bursting head through damaged pipe. Pull bursting head from one access point to another, fracturing old pipe and displacing it into surrounding soil. New HDPE pipe follows behind bursting head. Result: completely new pipe along same path.
Best For: Completely collapsed pipes, severe breaks where no structure remains, situations requiring diameter increase, pipes that cannot accept lining.
Advantages: Works when pipe completely collapsed, can upsize diameter 2-4 inches, HDPE pipe lasts 100+ years, no excavation along pipe length.
Timeline: 1-3 days depending on length and soil conditions.
How It Works: Target isolated damage with short liner section (2-4 feet). Install repair patch specifically at damaged location. Cure in place. Result: localized repair without lining entire line.
Best For: Isolated cracks or breaks in otherwise healthy pipe, connection point damage, single problem area, budget-conscious repairs when full lining unnecessary.
Advantages: Most cost-effective option, quick installation (2-3 hours), minimal materials, repairs only what needs repair.
Timeline: Same day completion typical.
The right repair method depends on damage type, extent, and pipe condition. Our video inspection shows exactly what’s wrong, then we recommend the most effective solution. Factors we consider:
We never upsell unnecessary services. We recommend what actually solves your problem permanently.
We insert HD camera through your sewer cleanout, recording complete footage of pipe interior from your home to street. Inspection reveals: damage type and severity, exact locations, pipe material and diameter, root intrusion extent, overall condition. You receive footage showing why repair is necessary and what method we recommend. Inspection typically takes 30-60 minutes.
After inspection, we review findings with you, showing exactly what’s wrong on video. We explain repair options, provide pricing for each approach, answer all questions, and help you choose the best solution. We present honest recommendations—if repair isn’t viable, we’ll say so and explain why replacement is necessary.
Before repair, we thoroughly clean your sewer line using hydro jetting or mechanical cleaning. Root cutting removes intrusive roots. Scale removal clears built-up deposits. Clean pipe walls ensure proper liner adhesion or clear path for bursting equipment. This critical step ensures repair success.
We execute the selected repair method:
For CIPP Lining: Insert liner, position throughout damaged section, inflate, cure 2-4 hours, reinstate connections. Total: 4-8 hours.
For Pipe Bursting: Set up equipment at access points, burst old pipe while pulling new pipe, make connections. Total: 6-12 hours depending on length.
For Point Repair: Position repair patch at damaged location, cure in place. Total: 2-3 hours.
After installation, we perform final camera inspection verifying perfect repair, test system with water flow, check all connections, restore access points, clean work area. Your sewer line is operational immediately with 50-100 year repair lifespan. We provide before/after video documentation.
Worried about sewer line damage? Get expert diagnosis and repair options.
When multiple fixtures backup simultaneously—toilets won’t flush, sinks drain slowly, tubs backup—your main sewer line has problems. Multiple backups indicate issues beyond simple clogs, suggesting structural damage requiring professional repair. Our emergency backup service provides 24/7 response.
All drains running slowly indicates main line restriction from damage, roots, or severe buildup. Unlike isolated slow drains (single fixture problems), house-wide slow drainage means your main line needs attention. Professional cleaning may resolve minor issues, but persistent problems indicate damage requiring repair.
Sewage smells in your yard indicate leaking sewer lines. Cracks or breaks allow sewage to escape into surrounding soil, creating noticeable odors especially in warm weather. Sewage leaks contaminate soil and groundwater—immediate professional assessment is critical.
Wet areas in your yard unrelated to rain, or developing sinkholes, indicate sewer line leaks. Escaping sewage saturates soil creating soft spots. Sinkholes form when leaking sewage erodes soil beneath surface. These signs indicate active leaks requiring immediate repair.
Sewage is fertilizer. Bright green, lush grass growing in specific lines or patches indicates underground sewer line leaks. The grass above leak points grows noticeably better than surrounding areas. This classic sign indicates slow leaks from cracked or separated joints.
Sewer line leaks beneath or near foundations cause soil erosion and settling that crack foundations. While not all foundation cracks result from sewer issues, cracks appearing with other signs (odors, slow drains, soggy areas) warrant sewer inspection.
Important: Don’t ignore these warning signs. Minor sewer line damage becomes major failures when left untreated. Early repair costs significantly less than emergency excavation and property restoration after catastrophic failures.
$3,000-$15,000
Complete trenchless repair, depending on method and extent
Sewer line repair costs vary based on damage extent, repair method, pipe length, depth, and accessibility:
Damage Extent: Isolated damage costs less than extensive deterioration throughout line length. Point repairs address single problem areas affordably. Multiple damage points require longer liner sections.
Pipe Length: Residential sewer lines typically run 50-150 feet from home to street. Longer lines require more materials and labor. Cost per foot decreases with length due to setup efficiency.
Pipe Depth: Standard burial depth (4-8 feet) is included in standard pricing. Deeper lines (8-12+ feet) increase excavation costs for access points. Depth affects equipment requirements and safety procedures.
Access Complexity: Existing cleanouts provide easy access keeping costs down. No cleanouts requires creating access points (additional $500-$1,500). Difficult access (under porches, through foundations) increases costs.
Root Removal Needs: Light root intrusion clears quickly. Severe root masses require extensive cutting, potentially needing specialized equipment. Root removal adds $500-$2,000 depending on severity.
Pipe Material: Most materials (cast iron, clay, PVC) repair similarly. Orangeburg pipe (fiber conduit) often cannot be lined if severely deteriorated, requiring bursting or replacement.

CIPP liners and HDPE pipes last 50-100+ years. Your repair likely outlasts your ownership. Permanent solution to sewer problems.
and all Wayne and Monroe County communities.
Most trenchless sewer line repairs complete in 1-2 days. Point repairs often finish in single day (4-6 hours). CIPP lining requires 1-2 days (includes curing time). Pipe bursting takes 1-3 days depending on length. Traditional repair requires 1-2 weeks plus additional time for property restoration.
No. Trenchless repair accesses through existing cleanouts or small access pits (typically 3×3 feet). We don’t excavate continuous trenches. Your landscaping, driveway, sidewalks, and trees remain intact. This is the primary advantage of trenchless technology.
We use HD video camera inspection to document your entire sewer line from inside. Camera reveals exact damage locations, type, and severity. We provide complete footage showing exactly what’s wrong and why repair is necessary. This precise diagnosis ensures we repair only what needs repair.
Most can. CIPP lining repairs any pipe maintaining basic structural shape—cracks, breaks, root damage, corrosion all repair successfully. Pipe bursting handles completely collapsed pipes. Exceptions include: pipes under certain structures without access, extremely shallow pipes, situations with severe physical barriers. We evaluate your specific situation and recommend best approach.
Thompson Trenchless provides lifetime workmanship warranty on all sewer line repairs. CIPP liner materials carry 50+ year manufacturer warranties. HDPE pipe used in bursting has 50-year to lifetime warranties. Our comprehensive warranty is transferable to future property owners.
Sewer line repair costs $3,000-$15,000 depending on method and extent. Point repairs ($3,000-$5,000) address isolated damage. Section lining ($5,000-$12,000) handles typical residential repairs. Full line lining or bursting ($8,000-$18,000) repairs extensive damage. This is 50-70% less than traditional repair when restoration costs are included.
Usually not. Most homeowners insurance excludes sewer line damage from coverage. However, if sewer line failure causes water damage to your home, that resulting damage may be covered. Check your specific policy. We provide detailed documentation if you need to file claims. Some home warranty programs cover sewer repairs—verify your coverage.
Trenchless sewer repairs last 50-100+ years. CIPP liners are essentially permanent with expected lifespan exceeding 100 years based on current data (technology invented 1970s, earliest installations still perfect). HDPE pipe lasts 100+ years. Your repair likely outlasts your ownership of the property. This is a permanent solution.
