Common Sewer Line Replacement Scenarios
Full Sewer Line Replacement
When the entire sewer line from your home to the street needs replacing due to age, material failure, or extensive damage.
Trenchless Pipe Bursting
A new pipe is pulled through the old one, breaking it apart. Minimal yard disruption compared to traditional excavation.
Cured-in-Place Pipe Lining
An epoxy-coated liner is inserted and cured inside the existing pipe, creating a new pipe within the old one.
Conventional Excavation
The traditional method: dig a trench, remove the old pipe, lay a new one. Sometimes the only option for severely collapsed lines.
Frequently Asked Questions
How much does sewer line replacement cost in Boulder, CO?
Full sewer line replacement in Boulder typically costs $3,000-$25,000. Trenchless methods run $4,000-$10,000 on average. Traditional excavation with yard restoration can exceed $15,000. Length of the line, depth, and access all affect pricing.
How long does sewer line replacement take?
Trenchless sewer replacement typically takes 1-2 days. Traditional excavation takes 3-5 days plus yard restoration time. Most plumbers in Boulder County can start within a week of the initial inspection.
Is trenchless sewer replacement worth it in Boulder?
Trenchless is usually worth it if your yard has landscaping, driveways, or structures over the sewer line. It costs more than basic excavation but saves thousands in restoration. Ask the pros below for a comparison quote.
Do I need a permit for sewer line replacement in Boulder County?
Yes — sewer line replacement in Boulder County requires a plumbing permit and inspection. Your plumber should handle the permit. Unpermitted work can cause problems when selling and may void insurance claims.
