Local notes
Leak Detection in Bellevue: what's different here
Homes from the 1960s through 1980s in Lake Hills and Crossroads are reaching the age when original supply lines and water heater connections start to fail, while downtown condo towers bring shared-riser and HOA rules into the job. In older Bellevue 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 Bellevue go through the City of Bellevue Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities
Most Bellevue homes are on city water and sewer, so the main shutoff and sewer cleanout are usually easy to find.
