5 Fall Maintenance Tips to Protect Your Home

By Bob Oates | October 5, 2025

As the seasons change in the Pacific Northwest, vibrant leaves and cooler weather signal more than just cozy sweaters — they’re also a reminder to get your home ready for the colder, stormier months ahead.

The 5 Most Famous Plumbers (and What We Can Learn From Them)

By Bob Oates | September 29, 2025

There’s something quietly heroic about plumbers. We tend to admire folks who do a job most of us never could—or would. Plumbers (alongside electricians) are the unsung gatekeepers of modern civilization. Without them, we might still rely on outhouses, city streets could flood with waste after every storm, and hot showers would remain a luxury.…

By Bob Oates | September 21, 2025

But here’s the problem: chemical drain cleaners rarely solve the real issue, and…

What Is Tree Root Invasion and How Is It Affecting Your Pipes?

By Bob Oates | August 24, 2025

Seattle’s tree-lined neighborhoods and steady rainfall are part of what makes living in the Pacific Northwest special. But those same elements also create the perfect storm for a hidden problem: tree root invasion in sewer lines. Roots naturally seek out moisture underground. If your home has older pipes made of clay or concrete, they’re especially…

Seattle Water Main Repair: What Homeowners Need to Know

By Bob Oates | August 18, 2025

Every Seattle home relies on a main water line to deliver fresh water from the city meter, a well, or a neighborhood water system. If your water main was installed before 1965, it’s likely made from galvanized steel. After 1978, newer materials like copper, PVC, or polyethylene became common. But no matter the material, water…
