Where Did the Water Come From? A Homeowner’s Damage Source Guide
The source shapes the cost, proof, contractor, and coverage questions.
Identify the likely water source before using the wrong calculator, calling the wrong trade, or assuming the wrong insurance path.
Water inside a home can look similar even when the decision path is different. A pipe leak, roof leak, HVAC drain overflow, sewer backup, floodwater, storm-created opening, and unknown source can point to different contractors, documents, costs, and coverage questions.

What should I do next?
Use the page to slow down the decision, save proof, check cost, and ask better questions.
Start here: Start with the first button or checklist, then use the decision packet if the answer affects money or paperwork.
Safety and claim boundary
Do not enter unsafe spaces to identify a source. Sewage, floodwater, electrical risk, sagging ceilings, gas smell, structural movement, or unsafe air are stop conditions.
Kefiw does not adjust claims, interpret your specific policy, receive private claim documents, or decide coverage. Do not send private insurance paperwork, claim photos, financial details, or personal information through Kefiw unless a page explicitly explains how that information is handled.
Proof disappears fast
Take wide photos, close-up photos, videos, source photos, room-by-room notes, and contents photos before cleanup changes the scene. Save receipts, contractor notes, moisture readings, disposal notes, and communication with the insurer or property manager.
Open damage document checklistPipe or appliance leak
A supply line, drain line, water heater, dishwasher, washer, refrigerator, or fixture can create sudden water damage. Save plumber or appliance notes that identify the source and whether it was repaired.
Roof leak, HVAC drain leak, or storm opening
Top-down water often has two scopes: the exterior or mechanical source and the interior water damage below it. Photograph the opening, ceiling, insulation, flooring, contents, and repair receipts.
Overflow, sewer, drain, floodwater, or surface water
A toilet/tub overflow, sewer backup, floor drain backup, stormwater, and rising floodwater can require different cleanup and coverage questions. Source and direction of water matter.
Unknown source
Unknown source is a documentation problem. Before demolition hides the path, ask which trade should diagnose it and save photos, moisture readings, and notes about where the water appeared.

Next: estimate, collect proof, compare the bid, then decide
Damage pages should end in a visible next action: calculator, checklist, decision packet, bid checker, or qualified professional question. Do not turn an unsafe room, vague contract, or policy-specific coverage question into a simple number.
Printable packet hook
The checklist content is visible on Kefiw. Use the printable packet only if you want a page to bring to the restoration company, adjuster, spouse, realtor, or rebuild contractor conversation.
Need a line-item estimate?
Use the questions above before building an estimate or talking with a restoration, rebuild, plumbing, roof, HVAC, mold, sewer, or fire/smoke provider. A cleaner quote separates emergency mitigation, cleanup, contents, and reconstruction instead of bundling everything into one vague number.
Kefiw does not adjust claims, interpret your specific policy, receive private claim documents, guarantee coverage, or tell you to delay emergency safety work.
