Find top rated sewer line repair pros in your area

In most cases, you’ll need to hire a plumber to construct and hook up your new sanitary sewer line. If the work also involves landscaping or excavation, the plumber may offer these services or recommend you hire an additional pro to handle those aspects.

To calculate the number of feet of sewer piping you’ll need to run from your house to the street and add the depth of the city main to the distance between the home and the main. This does not include the extra length needed to bypass obstacles such as tree roots or utility lines.

City sewer lines tend to run lower than other plumbing or utility lines to minimize the likelihood of backflow, so this number may be higher than you expect.

The estimated cost for a sewer hookup installation for an RV depends on the project’s complications. If you are connecting to an existing line on the property, you’ll pay less than if you must install a new line. The cost to hire a plumber runs from $45 to $200 per hour plus materials.

The average cost of an overhead sewer ranges from $8,000 to $10,000. This type uses pipes installed above ground to minimize backflow into a basement.

The cost to replace or repair a sewer line varies depending on the method used. On average, trenching costs $50 to $300 per foot, while trenchless line replacement costs between $60 and $200 per foot.

The total cost can be as little as $1,000 or as much as $25,000, with an average cost of about $3,500. This doesn’t include the cost of a sewer inspection, which may also be necessary before starting any work, depending on your situation.

Digging out old piping and replacing it can increase expenses. The existing sewer line might be below your gas line, which is often more expensive to redo. With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing. Many homeowners choose this method to avoid a full excavation, but it’s not appropriate for all homes. Ask a pro about your options.
