Signs You May Need Sewer Repair or Replacement

Recurring Sewer Backups

Slow Drains Throughout the Property

Slow Drains Throughout the Property

If multiple drains frequently back up or sewage returns into your home or business, it may indicate a damaged or blocked sewer line that requires professional repair.

When several sinks, tubs, or toilets drain slowly at the same time, the problem may be deeper within your main sewer line rather than an individual drain.

Tree Root Intrusion

Slow Drains Throughout the Property

Tree Root Intrusion

Tree roots naturally seek moisture and can invade sewer pipes through small cracks or loose joints. Left untreated, roots can cause serious blockages and pipe damage.

Sewage Odors

Soggy Areas in the Yard

Tree Root Intrusion

Persistent sewer odors inside or outside your property may indicate a cracked sewer pipe, broken sewer connection, or damaged plumbing vent that should be inspected promptly.

Sewer Repair & Camera Locating

Traditional Sewer Repair

Professional Sewer Camera Inspection

Professional Sewer Camera Inspection

Traditional sewer repair involves excavating the affected section of the sewer line to repair or replace damaged pipe. This method is often the best solution when sewer lines have collapsed, significant sections are severely damaged, or trenchless methods are not appropriate. While excavation may require restoring landscaping, driveways, or concrete, it provides full access to the damaged pipe and can be the most effective long-term solution in certain situations.

Every sewer repair begins with a professional sewer camera inspection. By locating the exact cause and location of the problem, we can recommend the most effective repair method—whether that's a spot repair, trenchless solution, or complete sewer line replacement. Accurate diagnosis helps prevent unnecessary work and ensures you receive the right solution for your plumbing system.

Frequently Asked Questions About Sewer Repair & Replacement

How do I know if I need sewer repair or replacement?

Recurring sewer backups, multiple slow drains, sewage odors, wet areas in your yard, or frequent drain clogs can all indicate a damaged sewer line. A professional sewer camera inspection is the best way to determine the condition of your sewer system and whether repair or replacement is the right solution.

Can tree roots damage my sewer line?

Yes. Tree roots naturally seek moisture and often enter sewer pipes through small cracks or loose joints. Over time, root intrusion can restrict flow, cause recurring backups, and even break the pipe. Early detection and repair can help prevent more extensive damage.

What causes a sewer line to need repair or replacement?

 Sewer lines can be damaged by tree roots, aging pipes, shifting soil, corrosion, cracks, or collapsed sections. A sewer camera inspection can help determine the condition of the line. 

How do you determine if a sewer line needs repair or replacement?

 We inspect the sewer line and evaluate the location and extent of the damage. Our plumbers can then explain the findings and recommend the appropriate repair or replacement. 

How long does sewer line replacement take?

Every project is different depending on the length of the sewer line, soil conditions, access, and repair method. After inspecting your sewer system, we'll provide a clear explanation of the recommended work and an estimated project timeline.

Do you perform sewer camera inspections?

Yes. Thomas Plumbing Inc. uses professional sewer camera inspection equipment to accurately locate blockages, root intrusion, broken pipes, offsets, corrosion, and other underground sewer problems. Camera inspections help us recommend the most effective repair solution while avoiding unnecessary excavation.
