The cost-effectiveness of sewer line replacement methods is a critical factor in your decision-making process. Trenchless methods, including pipe lining and pipe bursting, are known for being less invasive and subsequently can be more cost-effective than traditional excavation.

According to This Old House, costs for trenchless methods range from $60 to $250 per linear foot. While the initial cost may seem high, it’s important to consider the potential savings in terms of reduced labor and minimal landscape restoration required.

Method Cost (per linear foot)
Trenchless $60 – $250
Traditional Varies, often higher due to excavation

However, in some places like New York City, trenchless technologies such as pipelining are not recommended by licensed plumbers and are considered illegal. This is due to the potential for these methods to serve only as a temporary fix and possibly lead to more significant issues and costs in the future (Harris Water Main & Sewers).
