Leak Detection in Seattle: what's different here

Older Seattle housing stock means galvanized supply lines and clay or cast-iron sewer laterals are still common. In older Seattle homes, leaks hide in walls, slab joints and crawlspaces. We use acoustic and thermal tools to find them without opening more walls than necessary.

Permits and inspections

Finding a leak needs no permit; repairing or rerouting the pipe sometimes does. Mechanical and plumbing permits in Seattle go through Seattle Department of Construction and Inspections (SDCI). When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.

Utilities

Most Seattle homes are on city water and sewer, so the main shutoff and sewer cleanout are usually easy to find.
