Leak Detection in Alderwood Manor, WA

Aging Plumbing Meets Mature Landscaping

Alderwood Manor is one of Lynnwood's most established residential areas, with the bulk of its homes built between the 1970s and 1990s on larger lots shaded by mature evergreens and maples. Those big lots and big trees are part of the neighborhood's charm, but they are also the two main reasons we get called to Alderwood Manor homes. Original galvanized steel and early copper supply lines are now thirty to fifty years old, and underground service lines run long distances across root-filled yards.

Galvanized pipe corrodes from the inside out, so a line can look fine while its interior narrows and weakens until pinhole leaks appear behind walls or under floors. Copper from that era can suffer pitting corrosion that produces the same slow, hidden leaks. Outside, tree roots hunt for moisture along the water service line and sewer lateral, entering through tiny separations at joints and eventually cracking or blocking the pipe. The result is often a soggy strip of lawn, a water bill that creeps upward, or dampness that appears far from the actual break.

Because Alderwood Manor homes have longer pipe runs than newer compact lots, the leak can be many feet from where symptoms appear. Our acoustic leak detection equipment hears the exact point where pressurized water escapes, and electronic line tracing maps the pipe's path across the yard so we mark the dig site within inches. Inside the house, thermal imaging reveals moisture trapped in walls and under flooring before it becomes visible damage.
