Common Sewer & Drain Problems in Seattle
Seattle’s unique combination of older infrastructure, abundant trees, and heavy rainfall creates a perfect storm for sewer issues. Here’s what we see most often:
- Sewer line breaks and clogs (especially in older clay or cast iron pipes)
- Tree root intrusion – roots seek out moisture and can crack or clog pipes
- Slow drains, foul odors, and gurgling sounds – classic warning signs
- Sewage backups and wet spots in yards
- Unusually lush patches of grass – often a symptom of underground leaks
Seattle Success Stories
“A Queen Anne homeowner called us after repeated sewer backups. Our video inspection revealed a collapsed clay pipe. With trenchless repair, we fixed the problem in a single day—no trench, no mess. The homeowner couldn’t believe how fast and clean the process was.”
“In Ballard, we helped a family whose drains were constantly slow. Our team found tree roots had invaded their main sewer line. Hydro jetting cleared the roots, and a follow-up inspection gave them peace of mind.”
