Map before opening
Find the main shutoff, water heater, visible materials, fixture groups, cleanouts, and the path between the symptom and the stack or service.
Respect the building
Downtown rowhouses, Baker Park homes, older streets around Hood College, and newer communities along the city edges were built in different eras. Their plumbing can range from galvanized and aging copper to carefully updated PEX, often within the same house. Work around plaster, masonry, trim, and finished surfaces should include an access and restoration plan.
Prepare for winter
Identify exterior hose connections, pipes in unheated zones, crawlspaces, and vulnerable wall cavities before prolonged cold.
Compare scopes, not totals
Check whether quotes cover protection, access, disposal, permits, compatible materials, testing, finish repair, and warranty terms.
