Pay attention to a plumbing problem. Plumbing problems only get worse over time. Minor water leaks and other issues can escalate to costly disasters without immediate attention.

Most homeowners in Pomona are shocked when they learn the costs of plumbing repairs. Plumbing repairs can vary widely in cost depending on the nature and severity of the issue. The most expensive types of plumbing repairs are those that involve extensive labor, specialized equipment, or significant property damage. Here are some of the most costly plumbing repairs homeowners might encounter:

Sewer Line Repair or Replacement

$3,000 to $25,000+

Sewer line problems can include blockages, breaks, or root intrusions. Because a sewer line is located underground, repair or replacement can be a massive project.

Major Water Heater Repair or Replacement

$1,000 to $3,000+

Repairing or replacing a water heater, especially if it involves upgrading to a tankless system or correcting significant issues with the existing setup, can be expensive. Costs include the unit itself and labor for installation.

Burst Water Pipe Repair

$500 to $3,000+

Burst pipes can cause extensive water damage, requiring not only the repair of the pipe but also the remediation of water damage to walls, floors, and personal property. Costs can rise significantly if the burst occurs behind a wall or other inaccessible area.

Water Main Repair or Replacement

$1,000 to $5,000+

The water main is the primary pipe that supplies water to your home. Like the sewer line, the water main is located underground, making repairs and replacement a challenge.

Slab Leak Repair

$1,500 to $6,000+

Slab leaks occur when pipes beneath the concrete slab foundation of a home develop leaks. Repairing these leaks can involve substantial labor and materials.

Extensive Fixture Replacements

$500 to $2,500+ per fixture

Replacing fixtures like bathtubs, showers, or multiple faucets can be costly, especially if the work involves reconfiguring plumbing lines, removing old fixtures, and repairing surrounding areas.

Replacing Galvanized Pipes

$2,000 to $15,000+

Homes with older galvanized pipes may need a complete re-piping to upgrade to modern materials like copper or PEX. This process can be labor-intensive, involving the removal of old pipes and the installation of new ones throughout the home.

Extensive Mold Remediation Due to Plumbing Leaks

$500 to $6,000+

Hidden home water leaks can lead to mold growth. The more extensive the mold growth, the more difficult it is to remove. Getting rid of mold and cleaning contaminated surfaces requires professional remediation. The process can be extensive, involving the removal of mold, repairing the source of the leak, and replacing affected materials like drywall and insulation.


Regular maintenance and inspection can help you avoid costly plumbing repairs. Promptly addressing minor leaks, drips, and other problems in their earliest stages can prevent them from becoming major issues. Preventative measures include regular drain cleaning, insulating pipes, installing root barriers to prevent tree root intrusions, replacing corroded pipes, flushing your water heater’s tank, replacing the anode rod, and more.
