Common Sewer Repair Scenarios

Sewer Line Clog

Tree roots, grease buildup, or collapsed sections can block your main sewer line. Multiple drains backing up at once is the telltale sign.

Sewer Line Break

A broken sewer line causes sewage to leak into your yard or foundation. Foul odors, soggy patches, or unusually green grass over the line are warnings.

Bellied Sewer Pipe

A section of pipe that has sunk creates a low spot where waste collects. Camera inspection identifies the location and severity.

Root Intrusion

Tree roots seek out sewer line moisture and can crack or infiltrate pipes. Regular root cutting or pipe lining prevents full blockages.

Frequently Asked Questions

How much does sewer repair cost in Boulder, CO?
Sewer repair in Boulder ranges from $1,000-$4,000 for spot repairs to $3,000-$25,000 for full sewer line replacement. Trenchless methods (pipe lining, pipe bursting) often cost $4,000-$10,000 and avoid digging up your yard. Get a camera inspection quote first.
How do I know if my sewer line needs repair?
Warning signs include: multiple drains backing up simultaneously, gurgling sounds from toilets, sewage odors in your yard, soggy patches or sinkholes near the sewer line, and unexplained increases in your water bill.
What is trenchless sewer repair?
Trenchless methods repair or replace your sewer line without digging a trench through your yard. Pipe lining inserts a resin-coated liner inside the existing pipe; pipe bursting pulls a new pipe through while breaking the old one apart. Both minimize landscaping damage.
Does homeowners insurance cover sewer repair in CO?
Standard homeowners insurance in CO typically does NOT cover sewer line repair or replacement. Some insurers offer separate sewer line coverage as a rider for $5-15/month. Check with your agent — it's worth adding if your home has older sewer lines.
