Labor Cost

Labor cost is a major factor in repiping an existing home. The project requires experience and can take much longer than expected. Expect to pay labor costs of between $60 and $200 per hour for repiping projects.

Costs to Replumb a Home

Several factors affect the cost of removing and installing new pipes in an existing structure.

Part of the process of repiping consists of removing the existing pipes. This cost is often reflected in the bid as a labor and disposal cost and can range from $1,000 to $4,500.

Installing PEX Tubing

In addition to removing the old pipes, installing PEX tubing as the primary replacement material costs between $1.50 and $4 per linear foot or $1,500 to $4,000 for 1,000 linear feet of pipe.

Installing Copper Piping

Replacing old pipes with copper piping costs, on average, between $4 and $12 per linear foot or $4,000 and $12,000 for 1,000 linear feet of pipe and doesn’t include removal of the existing supply lines.

Installing Water Main (Meter to Home)

Installing or replacing a water main from the water meter to the home’s plumbing system costs between $30 and $60 per linear foot. However, the cost may exclude trip charges or other costs.

Install Water Main (Street to Home)

New construction projects require the water main to be connected to the municipal water supply. Expect to pay an average of $2,000 to $2,700 for the project.

Install Drain Lines (PVC)

Replacing the drain, waste and vent systems in an existing home costs an average of $4 to $8.50 per linear foot and can depend on access to the pipes and the pipe’s diameter.

Replace Galvanized Pipes

Replacing galvanized pipes requires removing and disposing of the old pipes and installing a completely new system. Expect to pay prices on the high side of the spectrum for this work.

Additional Costs to Consider

Other costs that affect the price of your plumbing installation or replacement.

Permit

A building permit is necessary for new plumbing or replacement projects. Your plumber will obtain the appropriate permits. The typical cost range is from $50 to $500 per project.

After Plumbing Repairs

Replacing a plumbing system often requires making holes in walls, ceilings or floors. Hiring a contractor or handyperson to perform drywall, plaster, wood or concrete repairs costs between $40 and $120 per hour.

Factors That Affect the Cost of Plumbing Installation or Replacement

Several factors affect the cost of all plumbing installations or replacement projects.

Scope of the Project

The scope of the plumbing project is the most significant factor affecting the project costs. The project scope includes the size of the home, materials used, access to the system, number of fixtures and rooms, labor hours and material quantities.

Fixture Quantity

Whether the project is for a single room or a whole house, the total number of plumbing fixtures being installed will require rough-in and finish plumbing.

Access to Plumbing

Pipes in existing homes may be buried under or behind walls and floors. Gaining sufficient access to the existing pipes, and creating enough space for new pipes, can increase the project’s cost.

Labor and Material Cost

Labor and material costs can fluctuate depending on market conditions and location. Securing a firm price quote for your project can offer protection from large price swings.

How to Know When You Need to Replumb Your Home

There are several ways to determine if your home requires new plumbing.

Water Color or Taste

Discolored water or a sudden change in the taste of your water indicates that corrosion has occurred inside the existing plumbing. Call a plumber to assess the situation and determine a solution.

Water Pressure

Prolonged or intermittent water pressure drops are a trouble indicator for plumbing supply lines.

Frequent Back-ups

Clogged drains or sinks and tubs that drain slowly are signs that your drain, waste and vent lines need replacement.

Water Leaks

Even a small water leak from a pipe or a pipe fitting could indicate more severe plumbing troubles. Have leaks repaired and inspected as soon as possible to avoid further water damage.

Age of Existing Plumbing

If your home’s plumbing is over 50 years old, it’s wise to have periodic professional inspections even if no signs of trouble have surfaced.
