FAQ

Got Questions About Drain Repairs? We’ve Got Answers

When something’s wrong below the surface, we’re here to help you get clarity—and a clean solution. Here’s what San Jose homeowners often ask when facing drain issues:

How do I know if I need a drain repair or full replacement?

Our team performs a thorough inspection using a sewer camera to determine the condition of your pipes. If the damage is localized (like a cracked section), we can repair it. If the entire line is compromised, a replacement may be recommended.

Recurring clogs may be caused by pipe sagging (bellies), tree root intrusion, grease buildup, or improper slope. Our inspections and hydro jetting services help identify and remove the source so clogs don’t keep coming back.

Hydro jetting uses high-pressure water to blast through blockages and clean pipe interiors. It’s ideal for tough clogs, sewer backups, or preventive maintenance before problems escalate.

Yes—we offer complete sewer line replacement services using traditional and trenchless methods. We’ll evaluate your specific situation and recommend the best solution for performance and budget.

Absolutely. Sometimes the problem isn’t the toilet—it’s the drain line behind it. We’ll determine if your toilet needs repair, replacement, or if the underlying drain requires service.
