LEAK DETECTION SERVICE IN SNOHOMISH COUNTY

Snohomish County spans from Puget Sound coast at Edmonds and Mukilteo east through Everett, Marysville, Lynnwood, and Bothell into the Cascade foothills near Sultan and Index. Action Leak Detection serves homeowners and businesses across the county — from dense urban Everett to rural acreage outside Granite Falls. Snohomish's housing stock is dominated by mid-century construction. Boeing's expansion through the 1950s and 60s brought thousands of new homes to Everett, Marysville, and Lynnwood — many still standing, and many still relying on the original copper or galvanized water lines installed when they were built. Copper pinhole leaks are especially common in homes from this era. The pinholes are tiny — sometimes the size of a pencil tip — but they release water continuously, and over weeks or months the cumulative damage can require slab opening or wall replacement. Polybutylene plumbing — the gray plastic pipe used widely in the 1980s and early 90s — appears in many Snohomish homes built during that era. Polybutylene fails reliably as it ages, often at fittings and elbows. If your home is roughly 30 to 40 years old and has plastic supply lines, this is worth a non-invasive pressure test to identify weak points before failure. Newer subdivisions across Mill Creek, Bothell, and Lake Stevens have mostly switched to PEX, which performs well — but irrigation systems installed alongside new construction are a different story. Sprinkler line breaks under landscaped yards are one of the most common calls we get from newer developments. Coastal homes in Edmonds and Mukilteo deal with the same salt-air corrosion concerns seen in Anacortes — copper and brass connections fail faster within a mile or two of saltwater than they do inland.
