Cedar Park Plumbers
4.8Reviewed for sewer line replacement
“I scheduled an appointment with this company almost a week prior to the date they were suppose to arrive. The service was to fix a leaky toilet. This was for a rental property. My tenant agreed to take off from work to meet the plumbers there. On the scheduled date and time, no one arrived.”
#2Caution

4.6Reviewed for sewer line replacement
“These guys came, drilled holes and tried to recreate the leaks but concluded that the leaks were just a result of excess water going through the grout and not faulty pipes. They spent ages with us and never charged us since there was no leak to fix.”
#3Strong Hire

4.9Reviewed for sewer line replacement
“They installed a new bathtub and toilet and re-piped my vanity from a single sink to a double. I am confident they can handle all my plumbing needs.”

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 Round Rock, TX?
Full sewer line replacement in Round Rock 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 Williamson County can start within a week of the initial inspection.
Is trenchless sewer replacement worth it in Round Rock?
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 Williamson County?
Yes — sewer line replacement in Williamson 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.
