Seattle’s Trusted Sewer & Drain Experts

Don’t let debris build‑up ruin your day. Regular drain cleaning keeps your plumbing functional and prevents backups. We remove obstructions, restore water flow and protect your pipes. Our technicians arrive promptly, evaluate your system and perform a professional cleaning using high‑pressure water and specialized tools. We’re here for scheduled maintenance and for emergency drain cleaning 24/7.

Older cast‑iron and galvanized pipes often suffer from hardened mineral deposits and corrosion, which can cause low water pressure and frequent clogs. Pipe descaling removes these deposits and restores smooth water flow. This service is ideal when hydro‑jetting isn’t enough and is especially common in older Seattle homes. By hiring our team, you ensure the job is done safely and professionally.

Know exactly what’s happening underground. Our sewer camera inspections involve inserting a high‑resolution camera through a cleanout. This live feed shows clogs, cracks, breaks and other imperfections so we can diagnose problems and recommend the right fix. If you’re experiencing gurgling toilets, slow drains, foul odors or backyard flooding, a camera inspection is the first step toward a permanent solution.

Repair or replace your pipes without digging up your yard. Our trenchless pipe repair uses camera inspections and hydro‑jetting to clean lines, then relines or replaces them through a single access point. This method avoids costly excavation, preserves your landscaping, and delivers durable, long‑lasting results. For severely damaged or old pipes, trenchless pipe replacement with pipe bursting creates a brand‑new line and eliminates the old one.

If your water line is leaking, corroded or outdated, NW Sewer & Drain can help. We replace old water lines using trenchless technology, avoiding major disruptions to your property. Our team understands the effects of wear, shifting ground and erosion, and installs durable water lines that will serve you for decades.

Foul smells, damp spots, rising water bills or lush patches in your yard may all signal a hidden leak. Leak detection is essential to prevent costly damage. Our technicians use gas detectors, video inspections and non‑destructive methods to pinpoint both sewer gas and water leaks. We find the smallest pinhole leaks and provide a lasting fix.

When pipes are severely broken or collapsed, excavation may be necessary. Our experts carefully locate the damage with a sewer camera and remove the broken sections. We minimize digging, repair the line and restore your property to better‑than‑new condition. Excavation is a last resort, and we offer trenchless alternatives whenever possible.
