Plumbing Services
Our comprehensive plumbing services address both residential and commercial needs. Specialized technicians handle leak repairs, fixture installations, and emergency plumbing issues with guaranteed parts and labor. We utilize high-pressure water jetting for drain clearing and maintain strict licensing standards. Serving King, Pierce, and Snohomish counties with same-day appointments and upfront pricing for all repairs.
Sewer Repair
Advanced sewer repair solutions include trenchless pipe replacement and traditional excavation when necessary. Our patented UV-curing technology enables same-day repairs without landscaping destruction. Every project begins with a free video inspection to identify root intrusion, cracks, or collapsed sections. Certified technicians guarantee workmanship and comply with Seattle Public Utilities regulations for side sewer permits and replacements.
Drain Cleaning
Professional drain cleaning services employ 4000 psi hydro jetting for complete pipe restoration. We remove tree root blockages and grease buildup without chemical damage to pipes. Spartan cable machines handle 2-12 inch lines while video inspections verify clearance. Maintenance recommendations follow each service to prevent recurring clogs in kitchen, bathroom, and main sewer lines.
Trenchless Sewer Repair
Our trenchless sewer repair specialists perform cured-in-place pipe (CIPP) relining with 50-year epoxy solutions. UV-cured liners create root-resistant replacement pipes through existing access points. This method preserves landscaping and requires only 4-6 hours for most repairs. Backed by industry-leading warranties, this technology reduces costs by eliminating excavation and restoration requirements for residential and commercial properties.
Water Main Repair
Emergency water main repair services identify and fix leaks causing high bills or foundation damage. Our licensed plumbers handle galvanized steel, copper, and polyethylene pipes with trenchless options when possible. Service includes pressure testing, leak detection, and full line replacement when necessary. We coordinate with Seattle Public Utilities for meter-side repairs and provide same-day service for burst lines.

Questions
What are common signs I need sewer repair?
Frequent backups, gurgling sounds, sewage odors, wet spots in yards, and slow drains across multiple fixtures typically indicate sewer line problems requiring professional inspection.
Which Seattle-specific factors damage sewer pipes?
Tree root intrusion, aging clay/concrete pipes, and ground movement particularly affect Seattle properties. Hydro jetting and video inspections help identify these common issues in Pacific Northwest soil conditions.
Do Seattle sewer repairs require permits?
Yes, Seattle side sewer permits are mandatory for repairs and replacements. Our team handles all permit applications and ensures compliance with local codes and Seattle Public Utilities requirements.
How long does trenchless sewer repair take?
Most trenchless repairs complete in one day using UV-cured pipe lining technology. Complex cases requiring excavation or multi-access point work may extend to 2-3 days depending on property conditions.
Will landscaping be damaged during repairs?
Trenchless methods preserve 90%+ of landscaping through minimal access points. Traditional excavation projects include detailed restoration plans discussed before work begins to minimize property impact.
