Don't Let A Clogged Sewer Ruin Your Day. Call In & Out Plumbing and Construction Now!

If you’re dealing with sewer backups, slow drains, foul odors, or recurring clogs, your sewer line may be damaged or failing. Our licensed plumbing team provides professional sewer line repair and full replacement services for residential and commercial properties throughout San Francisco and San Mateo County.

We specialize in diagnosing underground sewer problems quickly and delivering long-term, code-compliant solutions—not temporary fixes.

Ignoring sewer line issues can lead to property damage, health risks, and costly repairs. Call us immediately if you notice:

• Frequent drain backups or slow drains throughout the property
   
• Sewage odors inside or around your home
   
• Gurgling sounds from toilets or drains
   
• Sewage backing up into tubs, showers, or floor drains
   
• Patches of unusually green grass or soft soil in the yard
   
• Foundation moisture or unexplained water damage
   

These symptoms often indicate cracked pipes, root intrusion, collapsed lines, or deteriorated clay or cast-iron sewer piping, which are common in older Bay Area homes.

When replacement isn’t necessary, we focus on targeted sewer line repairs to restore proper flow and prevent future issues. Our repair solutions may include:

• Sewer pipe crack and joint repairs
   
• Root intrusion removal and pipe sealing
   
• Sectional pipe replacement
   
• Corrosion and deterioration repair
   
• Offset or bellied pipe correction
   

We use advanced diagnostics, including sewer camera inspections, to pinpoint the exact problem—so you only pay for what actually needs to be fixed.

If your sewer line is severely damaged or beyond repair, we offer complete sewer line replacement using modern materials designed to last decades.

• Collapsed or severely offset pipes
   
• Extensive root damage
   
• Old clay, Orangeburg, or cast-iron piping
   
• Repeated sewer backups despite prior repairs
   

We handle the entire process—from permits and inspections to excavation and final restoration—while ensuring full compliance with local San Francisco and San Mateo County codes

Whenever possible, we offer trenchless sewer replacement, which minimizes digging and disruption to your property.

• Minimal damage to landscaping, driveways, and sidewalks
   
• Faster completion times
   
• Durable, long-lasting pipe materials
   
• Cost-effective compared to traditional excavation
   

Our team will evaluate your property and determine whether trenchless technology is the right solution for your sewer system.

Every sewer repair or replacement starts with a high-resolution sewer camera inspection. This allows us to:

• Identify cracks, blockages, and root intrusion
   
• Locate collapsed or misaligned sections
   
• Determine repair vs. replacement accurately
   
• Provide transparent recommendations with no guesswork
   

You’ll see exactly what’s happening underground—no surprises, no upsells.
